The Benefit of Learning Good Hip Mechanics
Do you spend most of your workday sitting? Or are you older and noticing that
your activity level has decreased? Want to learn to sit, stand, and walk pain
free? Take pressure off your lower back, and SI joints. Increase hip strength
for better balance? Decrease stress on the knees when climbing up and down
stairs? Make it easier to get up out of a chair? Improve gait for walking,
running, bicycling, swimming.all other fitness activities? When we're feeling
unstable our stride shortens to protect balance our hips move less and less
freely, we can end up shuffling along to keep us on our feet. This loss of
hip strength and mobility can lead to an increased chance of a fall. Lack of
movement at the hip may also contribute to a decrease in bone density. Free
range of motion, strength, and flexibility at the hips is vital for enjoying
a long-life of activity to keep us feeling healthy and young.
The Benefit of Spine Stabilization for Efficient Hip Movement
Smooth and efficient movement of the hips begins with a strong pelvic floor
and good spine stability. Without this support as an anchor, free movement
at the hip is compromised. A pelvis that is held in a posterior tilt, as well
as, gripping or clenching in the front of the hips, will limit the ability
of the leg to move freely in the hip socket. Free hip movement is more challenging
to learn with Pilates Matwork. The muscles we've spent years overworking are
first to fire, which is why it's ideal for all students to utilize the entire
Pilates system and participate in both Mat & equipment programs.
Using Pilates Equipment to Keep Hips Moving Free & Easy
Spring resistance on the equipment helps teach the body how to move efficiently.
Figuring out how to stabilize the spine and get the legs moving independently
is easier to learn on the Reformer, Chair & Cadillac because the legs are
assisted by the support of the bar, pedal, springs, and straps. It is more
of a challenge to figure things out with Matwork, but with a little extra thought,
and prop or two to assist in changing habits, hip flexion can be free & easy
here too.
Stabilization for Efficient Hip Flexion
- Pelvic Floor Contraction - sitz bones, tailbone, and pubic bones should
pull together, like closing a drawstring. This action provides an anchor
to help stabilize the spine.
- Abdominals and back muscles contract to help maintain a functional & neutral
spine and pelvis. This will allow the legs to move independently from the
torso.
Ball & Socket Mechanics for Hip Flexion
If you're asked to place your hands on your hips chances are you'll put them
at waistline or top of the pelvis, which is not where the leg moves for flexion
of the hip. Instead place your hands on the fold where the leg meets the torso.
If the spine and pelvis are held still, the leg has a chance to flex freely
moving the ball in the socket, this is the real hip joint.
Think of the thigh bone like a teeter-totter. If one end goes up, the other
end has to go down. As the hip flexes, the thigh & knee move towards the
chest, the ball in the socket has to move down and back (posterior & inferior).
This action should start immediately when moving the leg. As the leg straightens
moving into hip extension, the thigh & knee move away from the chest. As
the leg extends the ball should move to a forward and up position in the socket
(superior & anterior).
- If the spine moves into a posterior tilt/scoop as the knee moves toward
the chest for hip flexion, the movement is initiating from the lower back
instead of the hips.
- If the hip flexors grip to pull the knee to the chest when flexing the
thigh, it will restrict the down and back movement of the ball in the socket
and the pelvis will tuck
- The spine should stay still. Both flexion & extension of the hip should
initiate from the ball changing places in the socket. The hamstrings should
be active as the knee bends to control the movement.
Exercises To Practice Hip Flexion
Footwork on the Reformer
- A parallel leg position will facilitate better mechanics to practice the
ball & socket movement for hip flexion.
- Push from the ball of the feet through the backs of the thighs as the legs
straighten.
- Think about pulling the sitz bones to the heels as the carriage returns,
actively controlling the motion.
What to watch for:
Look for the pelvis to remain in a still position. Can you see the ball
in the socket drop posterior/inferior as the hip flexes, and anterior/superior
as the leg extends. Pushing and pulling should not come from straightening
and bending the knees, but instead by moving the thigh bones away and towards
the center.
Footwork on the Chair
- On the High Chair, the back is still supported and the hips can flex into
a deeper range of motion.
- On the Wunda Chair, the back is unsupported. Maintaining a strong & stable
pelvis and torso will make this exercise more challenging.
What to watch for
Maintain the normal curves of the spine. Only push the pedal down as
far as you can without moving the pelvis. Be sure the initiation to move
the pedal is from the back of the thigh instead of the knees or feet. No
gripping in the front of the hip as the pedal comes up.
Footwork with A Ball
- This is a great way to practice if you don't have a Reformer, or have foot
issues where the pressure on the Reformer or Chair may be too much.
- Footwork here is a little more challenging for spine and pelvis stability.
The ball is less stable and may bob & weave while moving the legs if
there are any muscle imbalances.
- Similar to Footwork on the Reformer, lay on the back, place the heels on
the ball with the knees bent at 90 degrees or greater. Gently flex the hamstrings
to press the heels into the ball. Maintain a feeling of pressing down with
the back of the thighs as you roll the ball away and back in.
What to watch for
Spine and pelvis remain still - Engaged pelvic floor. Legs work evenly
and the ball rolls straight out and back in. Active glutes to push the legs
away, and psoas & hamstrings to draw the legs back in. Avoid bringing
the legs in by tensing the front of the thighs to bring the knees to the
chest.
Trapeze Table Leg Springs (with a Small Barrel)
- Using a small Barrel for Leg Springs on the Cadillac is an excellent way
to assist the legs with hip flexion, and while placing the spine and pelvis
in a more supported lumbar arch.
What to watch for
Normal curves of the spine. Lumbar support on the barrel. No wobbles
with the pelvis. The tailbone stays still, arching over the barrel as the
legs move towards the chest. Avoid locked knees. No gripping with the quadriceps
or hip flexors as the thighs lift. Look for space and a softness at the
fold in the front of the hip as the ball drops back and down in the socket
while the legs lift with the assistance of the spring.
A traditional Pilates workout provides opportunities to practice hip flexion
and extension exercise in a variety of positions. Some, like footwork on the
reformer - help stabilize the back and pelvis so we can become more conscious
of good hip articulation. Side leg kick front and back in matwork provides
more of a challenge. The spine should still be in a stabilized position but
there's no floor behind our back for reference to hold the body still while
the leg articulates from the hip. The goal..everything practiced lying down
should transfer to seated and standing exercises.
May you learn to hold things together while your
legs swing freely in Pilates & life!
