GENERAL PRINCIPLES TO OPTIMIZE YOUR EXECUTION
always stand / sit proud: keep head neutral (inline with spine relative to torso) chest up and torso tall
shoulders back and depressed
keep scapula contracted (zero internal / external rotation of shoulders or arching)
whenever executing an exercise from a vertical position, the torso should remain vertical or, ideally, ‘very slightly’ forward, pivoting from the hips, NOT from the spine.
when standing, in addition to the above, contract the glutes and hamstrings to prevent any hip sway (shove feet into the floor to assist)
- Rotating a pelvis helps to achieve that
always initiate from the working muscle (try to build tension prior to even executing)
aim to fully lengthen and fully shorten the muscle (unless otherwise stated)
A muscle is fully lengthened when its antagonist is fully contracted!
