Place the band around your ankles.
Lie on your stomach and activate your core muscles.
Push the right leg against the resistance of the band towards the ceiling while
pushing the left leg into the floor. Slowly return to starting position. Repeat 10 – 15 times.
Keep both legs straight while performing the exercise and prevent arching your back.
If you are able to do more than 10-15 reps, change to a heavier band.
