HOW: Start in a half kneeling position with a band anchored under your front foot, hold the band in each hand with the band positioned behind your head and neck. You can put something soft under your knee for comfort if desired. While keeping the rest of your body still and in good position, begin the exercise by performing an overhead shoulder press. Hold the end position for a moment (arms should be in line with your ears), slowly lower down and repeat.
FEEL: This should feel like an upper body workout, specifically your deltoids, triceps, and upper back muscles. You should feel your core and abs working as well to maintain balance and not excessively arch your back. The side you're kneeling on - you will feel that hip working as well.
COMPENSATION: Keep the rest of your body still, do not excessively arch or bend your back. Do not use momentum to your advantage to move your arms overhead. Do not excessively shrug.
