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.
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.
Inchworm with up and down dogs
The classic inchworm mobility drill, with some added up and down dog transitions, as part of the movement preparation package for the Australian Aurora's Dragon Boat Team for the 2015 World Championships.
When a runner's trunk and pelvis position breaks down, send them back to the wall to assist stability. Cue them to press into the wall, which provides compression sensation to the mechanoreceptors in the spine, via the upper limb. This causes reflex stabilisation, permitting better mobilisation of the lower limb.
Maintain an isometric stance on the ground.
Start with isometric holds (great for achilles rehab) for 10-15 seconds.
Progress to alternating march.
Then to quick switches.
Add a "load and lift" - also part of achilles rehab (except for those who don't tolerate load at length), to check for single leg triple flexion force absorption competency - a great acceleration mechanics drill.
