By raising an arm and leg from the floor while in tabletop, you're intentionally throwing off your body's stability, forcing your core to work hard at keeping you steady. And your obliques take on a lot of that work.
- Begin on all fours with your hands directly under your shoulders and your knees directly under your hips.
- Pull your abs in to your spine. Keeping your back and pelvis still and stable, reach your right arm forward and left leg back. You may sense that your pelvis wants to rock or your rib cage wants to dip to the floor; focus on holding steady as you reach through your left heel (which has the added benefit of engaging your legs and glutes).
- Place your hand and knee on the floor, returning to your starting position. Repeat on the other side to complete one rep.
