Boat pose

Sit with your feet on the floor, knees bent, hands beneath your knees for support. Keeping your chest lifted and shoulders back, engage your ab muscles and raise your lower legs until they are parallel to the floor (your knees should still be bent) and you are balancing on your sitting bones.

If this feels comfortable, begin to straighten your legs (stop if you feel any discomfort in your back) and stretch your arms forward. Hold for 5–15 breaths, then release. Repeat up to 5 times.
