HOW: Start in a standing position with a band anchored under your feet, hold the band in each hand at shoulder height with your palms facing forward. Begin the exercise by keeping the rest of your body still and then performing an overhead press. Then, while maintaining this overhead position, pull the band apart by bringing your hands out - down and laterally until your arms are lined up with your torso at shoulder height. Return to the overhead press position, then return to starting position and repeat.
FEEL: This should feel like an upper body workout, specifically your deltoids, traps, and upper back muscles. You should feel your shoulder blades working a lot with this exercise.
COMPENSATION: Keep the rest of your body still, do not excessively arch or bend your back. Do not use momentum to raise your arms. Do not let your elbows excessively bend. Do not excessively shrug.
