STARTING POSITION:
Select the appropriate strength of the band. Lie on your back on a foam roller. The roller should be under your spine and head. Place your feet flat on the floor. Grab the band from the ends and place it under the roller, behind your head. Fully extend the arms so that they are perpendicular to the floor. The band should have tension from the beginning of the movement. Contract your pelvic floor and core.
MOVEMENT:
Start lowering the hands only moving the forearms until they are next your eyes while you inhale. Return to the starting position in a strong movement by extending your arms while you exhale.
TIPS: While your are doing the exercise, move only the elbows joint, make sure you don't move any other part of your body.
