2. Single Leg Raises
Lie on your back on the floor with your legs straight. Put your hands under your rear so they are nice and stabilized. This also helps keep you balanced. Now, raise your right leg straight up in the air so it forms an L with the other leg. Keep your core tight and do this 20 times, then repeat on the other side. I recommend doing two sets of these each day. This is a great exercise for your abs, your legs, and your entire core. You’ll really feel it the next day too!
