This circular movement stretches the muscles in your abs, chest, and back while engaging your core muscles at the same time.
How to do it: Stand with feet wider than hip width, knees slightly bent, arms extended overhead, palms facing in. Keeping your pelvis still, slowly start to reach your upper body and arms to the left, then overhead (extending your spine and looking up), and then to the right, tracing a full circle. Repeat 5 times to the left, then 5 times to the right.
