Lots of value here:
1. Passive hip flexion and external rotation
2. Same, but with more tension across the front and back of the trunk
3. In quadruped, adding opposite hip extension stimulus and anterior trunk activation to improve pelvis position relative to the mobilised hip
4. In supine, adding anterior trunk activation to improve pelvis position relative to the mobilised hip
Always grateful to Coach Cam Elliott @coach_cam for his great mindful techniques that mimic what I do clinically to change behaviour. This is his technique, following on what he sees me do by hand and in the clinic.
Oscillating Technique with Isometric Stabilisation (OTIS) & Impulse Technique with Isometric Stabilisation (ITIS)
A whole body movement exploration for pre-training and pre-competition.
In standing, flex on hip, grab it and pull it high, maintaining tall posture. Step out into a lunge with the right foot. Grab the right foot by right hand, place the left hand alongside it, shoulder-width apart. On exhalation, lunge further into a stretch. Keep the back knee off the ground. Take the right hand off the foot and twist the trunk towards the front foot, raising the right hand towards the ceiling, reaching vertically. Return to the ground with both hands down, then shift weight backwards to create a stretch on the front leg, then step up to the start position and repeat on the other side.
Improve hip extension range in weight bearing.
In half kneeling, place both hands on the front knee.
Press down on the front knee, with elbows locked.
Lunge into hip extension on the weight bearing leg.
Pressing down on the front leg generates anterior torso activation, approximates the ribs to pelvis, thus stabilizing the lumbar spine.
An unmanaged hip extension limitation has implications for all lower quarter patterns, since reduced joint mobility can affect extension, rotation and flexion.
Correcting split squat drills is best done at a subconscious level, since stability is reflex driven, no conscious driven.
The use of a FMT (Functional Movement Tubing) or kettlebell, introduces destabilising force in planes of movement (coronal and transverse) that is perturbing the main plane of movement - sagittal.
In the presence of minimum, or improved, mobility, to get into the start and finish position, the FMT creates reactive neuromuscular training to the pattern, improving the pattern for other training events that require power in a split squat, like the Bulgarian Split Squat.
The Baby Get Up
I use the BGU to improve the pattern of trunk flexion and rotation.
I also use it to provide an opportunity to challenge hip and sacro-iliac joint stability in the presence of other body part movements.
The bottom arm moves into internal rotation until it meets it's end-range, at which point the person sits up. The ""screwing home" of the shoulder creates a stable joint. As the person continues to press the hand down to the floor, the shoulder girdle is brought with it, pushing the trunk off the ground. Actively sit up.
Place the top hand against the "up" leg. As you sit up, keep the hand/arm against the inside of the knee.
The top leg, remaining in active abduction and external rotation, creates hip and sacro-iliac joint stability.
The three stable areas, bottom arm, bottom hip/hemipelvis and top hip/hemipelvis, provide a stable base for the trunk to flex and rotate around.
In other words, activating stabilisers permits expression of mobilisers.
Top leg collapses; bottom arm loses connection with the ground; jerky trunk flexion and rotation; bottom leg loses extended position.
I use this drill as a supplement, to activate anterior core whilst stimulating the hip drive required for acceleration.
Ankle grab whilst walking is a test of dynamic single leg stance control with contralateral hip extension, knee flexion & tibial rotation. Ideally you'd already clear the ankle mobility, split kneeling hip/core control, hip extension, knee flexion and tibial rotation. Then this drill brings together the whole pattern with ankle & knee stability & motor control.
One of the more difficult movement preparation drills - the quad stretch to toe touch - challenges dynamic stability on the stance leg, and mobility on the other leg.
