Iso Sit Up Rotations
To do the Iso Sit Up Rotations, sit on the ground with your legs out straight in front of you about hip-width apart. Cross your arms over your chest and then lean back. Hinge back halfway between seated and lying down. The more you sit straight up, the easier the move will be.
Then rotate toward the right as much as you can while staying hinged back. Drop your right elbow toward the ground by twisting as much as possible while staying hinged back. Pause for a second then rotate to the left. Do not sit up between rotations. Stay hinged back and really engage your abs. Do not let your feet come up. Engage your core and even your legs.
Twist to the left and pause on the left. Do not sit up at any time. Stay leaned back with your core engaged as you twist from side to side and pause on each side.
If you feel your low back or can’t keep your legs on the ground, do not hinge back as far.
