CONCEPT

Compás

The compás is the biomechanical reference for the opening between the legs: the distance and angle at which the feet are placed on the floor to define the base of the stance. In the eagle gesture, the open compás sets the width from which the femur can rotate externally without the pelvis losing its neutrality. It is not a fixed position; it is the geometric variable the body modulates based on how much rotation is available at hip and ankle.

Why it matters

External rotation requires joint space, and the compás is what creates that space. When the opening between the legs is too narrow, the head of the femur finds no room and the rotation spills over to the knee or the foot. When it is too wide, the pelvis is dragged into anterior tilt and the torso compensates forward. Finding the correct compás for one's own body is a prerequisite for the eagle stance to be held by biomechanics rather than by effort.

How to feel it

The body perceives the correct compás as a wide but stable base, with the heels firm on the floor and no sense of pull on the inner thighs. The adductors are active but not shortened, the knees align above the feet and the pelvis is felt as suspended between the legs, not falling forward. When the compás is opened in Routine 1, the skater notices how external rotation gains range without changing the pelvic placement.

Common mistakes

  • Opening the compás by forcing the aperture and letting the pelvis fall into anterior tilt.
  • Closing the compás to feel more control and sacrificing the range of external rotation.
  • Seeking the opening only with the feet, without accompanying the movement from the hip.
  • Keeping the knees turned inward as the compás widens, losing knee-foot alignment.

CONCEPT

Psoas

The iliopsoas is the deep muscle that connects the lumbar spine and the pelvis to the inner part of the femur. It acts as the main hip flexor and as a stabilizer of pelvic placement: when it works in a coordinated way, it keeps the pelvis in its neutral position while the leg moves. Its tone and its length directly condition hip flexion range and the availability for deep rotations.

Why it matters

In the eagle gesture the psoas participates twice over: it holds the pelvis neutral during external rotation and it allows the knee to move toward the chest in the adduction and weight-transfer phases. If it is shortened or weak, it drags the pelvis into anterior tilt and the hip loses the axis on which the femur rotates. Re-educating the psoas is re-educating the very base from which the stance is organized.

How to feel it

The psoas feels deep, hard to isolate at first sight. In hip flexion with the leg crossed behind, the muscle activates as an inner band that stabilizes the pelvis. In the face-down stretch with the hands reaching for the feet, a long tension is felt from the groin toward the anterior thigh. When the psoas is integrated into the gesture, the leg lifts without the pelvis losing its placement.

Common mistakes

  • Confusing psoas activation with rectus femoris activation.
  • Stretching the psoas without activating it, leaving the pelvis in anterior tilt during the stretch.
  • Seeking hip flexion from the knee rather than from the depth of the femoral head.

CONCEPT

External rotation

External rotation is the turn of the head of the femur inside the acetabulum, with the pelvis held in a neutral position. It is a local movement of the hip — not of the foot or the knee — that opens the line of the thigh outward from the body. In parallel-skate skating, it is the gesture that allows the edge of the skate to align with the body's trajectory and that lets the eagle stance be held without compensations.

Why it matters

The eagle is essentially a stance of sustained external rotation. Everything else — the compás, ankle abduction, torso placement — exists to hold and enhance that rotation. If the turn arises from the foot or the knee, the gesture degrades the moment weight or speed is added. Only when the rotation is produced from the hip can it become resistant over time and be transferred cleanly onto skates.

How to feel it

Correct external rotation is felt as an activation of the outer part of the hip and of the glute, with the femur rotating under a still pelvis. The skater perceives the axis of the thigh moving outward without the knee collapsing inward or the foot lifting off the floor. The pelvis stays neutral: it doesn't go back and forth — it is the head of the femur that rotates.

Common mistakes

  • Confusing external hip rotation with turning the foot on the floor.
  • Letting the pelvis tilt into anterior tilt while seeking more range.
  • Letting the knee collapse inward instead of keeping it aligned above the foot.
  • Driving the rotation from the ankle, leaving the hip passive.

CONCEPT

Ankle abduction

Ankle abduction is the movement of the outer part of the foot outward, with the knee held stable. It is an isolated movement of the ankle — not of the femur or the knee — that makes the outer edge of the skate drop and releases the inner edge. In the eagle stance, abduction of the front foot is what indicates the direction of displacement.

Why it matters

The edge of the skate does not drop by wish, it drops because the ankle takes it there. Without active abduction the foot does not generate the straight line that characterizes the stance, and the skater ends up seeking the edge with the weight of the body instead of with the musculature of the foot. It is also the segment that isolates hip rotation from foot rotation: when the ankle works autonomously, the knee is free to stay aligned above the foot.

How to feel it

Isolated abduction is perceived as a precise pull on the outer part of the foot, with the sensation that the heel lifts slightly and the inner edge releases from the floor. The knee should feel still — it doesn't move a hair — while the foot turns. Inside the skate boot, abduction translates into a clear pressure on the outer edge without the body having to lean.

Common mistakes

  • Rotating the foot from the knee instead of from the ankle.
  • Involving the hip when the exercise asks for isolated foot movement.
  • Chasing passive range before having built the active strength that sustains the edge.

CONCEPT

Anterior pelvic tilt

Anterior pelvic tilt is the tipping of the pelvis forward: the iliac crests lean toward the front and the pubis falls back, arching the lumbar. It is a frequent misalignment in bodies that have not trained the deep abdominal girdle, and it appears automatically when the body tries to gain hip aperture by dropping the pelvis instead of rotating the femur.

Why it matters

External rotation demands a neutral pelvis: if the pelvis is tipped forward, the axis on which the femur rotates shifts and the available range shrinks. Correcting the tilt is not a cosmetic detail; it is the condition for the eagle stance to stop being sustained by compensations. The pelvis stays neutral, it doesn't go back and forth — it is the head of the femur that rotates.

How to feel it

The posterior tilt sought is felt as a deep activation of the transverse abdominis and the pelvic floor, with the pubis rising slightly and the lumbar lengthening toward the floor. The heels are perceived as advanced relative to the hips, and the pelvis is held as a horizontal base on which the torso rests aligned. The sensation is one of anchoring, not of stiffness.

Common mistakes

  • Confusing posterior pelvic tilt with clenching the glutes.
  • Seeking neutrality only from the lumbar and not from the deep abdomen.
  • Losing the posterior tilt when pronouncing knee flexion in the open compás.
  • Compensating the anterior tilt with the torso forward instead of with the pelvis from below.

CONCEPT

Center and line of gravity

The center of gravity is the theoretical point where the mass of the body concentrates; the line of gravity is the vertical that descends from that point down to the base of support. Both are biomechanical references that determine whether the body holds itself through its own structure or needs muscular compensations to keep from falling. In the eagle, the base of support changes constantly and the line of gravity becomes the dynamic parameter to be managed.

Why it matters

A skater can have balance in static and still lose the gesture when moving, because the line of gravity leaves the base of support the moment the body starts to move. Knowing where one's own center is and anticipating where it is heading turns passive balance into active control. Knowing where the weight is is going to help you enormously to control that weight.

How to feel it

The center is felt as a deep point around the navel, slightly behind. When the line of gravity falls inside the base, the body feels light, with no need to hold onto anything. When the line starts drifting out, an anticipatory tension appears in the torso or the arms, and that inner warning allows correction before losing the stance.

Common mistakes

  • Seeking balance with arms and torso instead of managing the weight from the pelvis.
  • Keeping the center fixed when the displacement asks to move it with the body.
  • Neglecting the line of gravity in displacement and holding the stance by muscular effort alone.

CONCEPT

Proprioception

Proprioception is the body's capacity to perceive itself from within: to know where the segments are in space, which muscles are active and how much weight is on each support, without recourse to sight. It is the inner information on which any technical correction is built and without which external instructions are forgotten the moment the context changes.

Why it matters

Without proprioception a correction only holds while someone is remembering it from the outside. The program's goal is not to reproduce the shape of the gesture but to feel it from within: to feel the glute activating, to feel where the weight is placed, to notice if the pelvis has drifted. To be able to control the movement you need to feel the movement; that is the premise that structures the three routines.

How to feel it

Trained proprioception translates into the quiet certainty of where each part of the body is. The skater perceives hip rotation without looking at it, senses whether the foot is abducted, distinguishes whether the weight is more on the metatarsal or on the heel. Antagonist movements — external and internal rotation in the same set — reinforce that inner reading because they force the body to compare both ranges.

Common mistakes

  • Executing the gesture from memory without collecting the inner information.
  • Correcting from the mirror or from external instruction without verifying from within.
  • Skipping straight to the complex gesture without first having felt each segment separately.

CONCEPT

Weight transfer

Weight transfer is the conscious shifting of the body's mass between available points of support. In skating, it is the operation that decides which leg holds the stance and which one indicates the direction; in the eagle gesture, it is what allows the static gesture to become the Mohawk in motion. It is not a passive consequence of the movement: it is a variable the skater manipulates with intention.

Why it matters

The eagle is not a static stance; it is held while the body travels. Without the capacity to transfer weight deliberately, the only option is to spread it between two supports, which forecloses the geometry of the Mohawk. Once endurance and proprioception are consolidated, the weight can be given fully to the back leg while the front leg indicates the direction with the abduction of the ankle.

How to feel it

The transfer feels like a clear decision of the center that pulls the weight toward a specific support, without the torso having to lean. The leg that receives the weight feels loaded and active; the leg that is released stays available to articulate the direction. In the weight shifts with torsion in Routine 1, this control appears for the first time as a trainable parameter.

Common mistakes

  • Shifting the weight from the torso instead of from the pelvis.
  • Splitting the weight evenly when the gesture asks to commit it to a single leg.
  • Losing external rotation when transferring the weight, letting the hip close.

CONCEPT

Conscious breathing

Conscious breathing is the deliberate pattern of inhalation and exhalation that accompanies every exercise, with pelvic floor and abdominal muscles active during the effort phase. It is not just about oxygenating: it is about integrating breathing into muscular contraction so that each exhalation coincides with the moment of maximum work and sustains the placement of the center.

Why it matters

In long routines of endurance over time, breathing is what separates a sustainable gesture from a rigid one. Exhaling at maximum effort activates the transverse and the pelvic floor, and the pelvis finds its neutrality with far less cost. Holding conscious breathing in every exercise is an instruction repeated explicitly at the start of Routine 1 and kept as a norm across the three routines.

How to feel it

Active breathing is felt as a lateral and posterior expansion of the ribs on inhalation, and as a deep closing of the lower abdomen on exhalation. The navel pulls toward the spine, the pelvic floor lifts slightly and the center organizes itself. When the pattern is integrated, each exhalation coincides with the hardest moment of the exercise and makes it unexpectedly easier.

Common mistakes

  • Holding the breath during the effort, tensing neck and shoulders.
  • Inhaling at the peak of the effort instead of exhaling.
  • Breathing only with the chest, without activating the pelvic floor or the transverse.

CONCEPT

Holding the stance

Holding the stance is the capacity to keep the correct gesture over time, not only at the instant of reaching it. It is a matter of strength along the parameter of time: not spot strength or explosive strength, but specific muscular endurance that allows the position to be prolonged while the body moves on skates.

Why it matters

In the analysis of the assessment, the coach identifies endurance as the program's primary area of opportunity: sustained strength has to be increased and it has to be done with external load to simulate the weight of the boots. Without endurance the gesture exists as shape but not as capacity. All the routines are structured around this idea, with four to ten second holds per repetition.

How to feel it

Holding well feels like work distributed across several muscle groups, without hot spots of acute effort. The transverse and the glutes hold on; the breathing stays fluid; the position does not degrade even as second five turns into second ten. When the hold is correct, at the end of the repetition the body can start the next one without seeking refuge in compensations.

Common mistakes

  • Reaching the position with explosive strength and losing it before completing the required time.
  • Holding with the torso or the arms instead of with the center and the rotators.
  • Reducing the quality of the gesture in order to hold for longer.
  • Holding the breath during the hold instead of accompanying it with active exhalations.

CONCEPT

Mohawk

The Mohawk — also known in Spanish as the eagle stance — is a skating gesture in which the skater changes direction, typically from skating forward to skating backward or vice versa, by means of a deep external rotation of one leg placed in abduction relative to the other, without lifting the skates off the floor. In the project, the Mohawk is the technical destination: the stance held and transferred into motion.

Why it matters

The entire program is designed to arrive here. The off-skate exercises build the external rotation, the endurance, the proprioception and the weight transfer the Mohawk demands. Without that foundation the gesture is impossible or unsustainable; with it, it becomes a natural consequence of a trained body. Routine 3 dedicates its final phase to the search for the gesture on skates, with the explicit goal of integrating it into displacement.

How to feel it

A well-executed Mohawk feels like an opening of the body toward a new front, with the weight fully over the back leg and the front leg free to indicate the direction with the abduction of the ankle. The torso opens but without torsion; the pelvis tilts the line of the body slightly toward the new trajectory. It is a gesture of sustained rotation, not of an abrupt turn.

Common mistakes

  • Seeking the change of direction with the torso instead of with the hip.
  • Lifting the skate off the floor during the external rotation.
  • Losing the alignment between pelvis and torso, allowing torsion to appear.
  • Executing the Mohawk in motion without first having consolidated the static stance.

CONCEPT

Goddess pose

The goddess pose is a reference borrowed from dance and yoga: standing, legs apart wider than hip-width, knees flexed and opened in external rotation, pelvis neutral, torso vertical. Carolina Miranda uses it as a pedagogical setup because it reproduces the geometry of the eagle off the skate and allows pelvic placement to be re-educated without the added complexity of the edge.

Why it matters

Before the gesture lives on skates it has to live on the floor. The goddess pose offers a safe space where the open compás, external rotation and posterior pelvic tilt can be practiced until they become familiar. It appears in the three routines: as an eight-second hold in the warmup, as a base for lateral weight shifts, and as a mental reference for the on-skates gesture.

How to feel it

The body is perceived as stable over a broad base, with the knees dropping right above the feet and the pelvis aligned horizontally between the legs. Breathing is wide; the torso holds vertical without effort; the adductors are active but not locked. It is a position that can be held for a long time when external rotation arises from the hip.

Common mistakes

  • Losing the external rotation by letting the knees collapse inward.
  • Tipping the pelvis into anterior tilt as knee flexion is pronounced.
  • Holding with the torso leaning forward instead of keeping it vertical.

CONCEPT

Lunge

The lunge is a deep-stride position: one leg forward in knee flexion, the other back extended or semi-flexed, with the front knee aligned above the foot and the pelvis in neutrality. In Routine 3 it is executed with a resistance band around the legs to resist the step and force the external rotators to activate during the transition.

Why it matters

The lunge trains the stability of the knee under load and the capacity to keep the hip aligned while shifting the weight. It appears as a specific block in Routine 3 because it is the bridge between the deep squat with rotation and the eagle gesture on skates: it reproduces the geometry of one leg committed to the weight and another free to indicate the direction.

How to feel it

In a correct lunge the front knee feels firm, aligned above the foot and without collapsing inward. The back leg activates glute and adductor; the pelvis stays horizontal, without tipping. With the resistance band in place, the resistance forces the external rotators to work at every step, generating a clear activation on the outer part of the hips.

Common mistakes

  • Letting the front knee collapse inward during the flexion.
  • Leaning the torso forward instead of keeping it vertical over the pelvis.
  • Stepping quickly and losing the resistance of the band.

CONCEPT

Weight shifts

Weight shifts are the active transfer of the body's mass between the available points of support, without losing the overall stance. They are practiced side to side in goddess pose, diagonally with torsions from external rotation, and on skates with displacement toward the dominant leg. They are the basic operation on which the full transfer of the Mohawk is later built.

Why it matters

Before committing all the weight to one leg you have to learn to move it with precision. Weight shifts teach the body to change the base and the placement of the torso while keeping the vertical, and to read with proprioception where the mass is at each instant. It is preliminary work that is indispensable for the more committed transfers of Routines 2 and 3.

How to feel it

The skater perceives how the center shifts deliberately to one side without the torso automatically following the weight. The legs stabilize by turns: the one receiving activates, the one released stays available. Breathing continues without interruption during the transfer, and the gesture feels controlled, not reactive.

Common mistakes

  • Shifting the weight by leaning the torso to the side instead of moving the center underneath.
  • Losing the external rotation as the side changes.
  • Executing the shift abruptly, without proprioception of the path.

CONCEPT

Gesture exploration

Gesture exploration is the exploratory work that structures phase 3 of Routine 3: a list of thirteen variations the skater executes on skates in order to discover which combination of weight distribution, torso orientation, arm opening and leg rotation lets them flow in the position. It is not a prescription but an exploration; the answer does not lie in a single variable, but in the combination the skater's body finds.

Why it matters

The final gesture is not reproduced by external instruction; it is discovered by integration. After months of specific work on mobility, endurance and proprioception, the body is ready to test variants and notice which ones work to flow in the position. Gesture exploration recognizes that every body has its own biomechanics and that the optimal Mohawk emerges from exploration, not from imitation.

How to feel it

The work feels patient and conscious: each variation is repeated at least five times to integrate the sensation before moving to the next. The skater notices which weight distribution makes the gesture lighter, which torso orientation frees the hip, which combination allows the line of the body to be kept with less effort. The answer arrives from within, not from without.

Common mistakes

  • Starting the exploration without having consolidated the capacities of the previous routines.
  • Trying each variation only once without giving time to integrate the sensation.
  • Looking for a single perfect variation instead of combining several.
  • Discarding uncomfortable variations without having practiced them patiently.
