Who knew tracing a letter could be so difficult? You’ll feel your entire abdominal wall working during this abs exercise.
How to do it: Start seated, facing your bent knees. Place both hands on the floor just behind your hips, and lean back to pick both feet up off the floor, keeping knees bent. Next, lean further back, bending your elbows to the floor and extend your legs further away from your body, while tracing a letter ‘U’ with your bent knees. Try to lean back so that your elbows touch the floor at the bottom of your ‘U’, and then sit up as you finish it. That’s one rep. Repeat 20 times total.
Bonus tip: Focus on bracing your abs in to help support your back during this move. If you start to feel any strain your lower back, don’t recline as far back.
