This is an excellent stretch for the back and sides.
Instructions
Sit on the floor with your legs stretched out in front of you, slightly apart. Put your hands in the pockets of the Pilates band and keep your hands out in front of you at approximately shoulder height. You should be sitting very tall.
Inhale, then exhale and fold your upper body over your legs, trying to prevent your spine from rounding. Reach your hands forward as if you’re trying to reach them past your feet.
Inhale, then exhale and reach your left hand past your right foot. Slowly return yourself to the start position. Repeat 2-3 times to each side.
