Here's a whole body exercise for you to try: Leg Pull Down (nobody said that Pilates moves had poetic or lovely names). I love this move because it works your arms, abs, glutes and hamstrings all at the same time. Before you start be sure to circle your wrists a couple of times in each direction to warm up the joints.
Start in a plank position. Place your hands under your shoulders with feet hip distance apart.
Spread and press your fingers into the floor to help take pressure off of your wrists.
Scoop your deep abs up toward your spine. Reach long through your heels to activate the back of your legs.
Reach equally through the top of your head to create stability from these opposing energies as your feet and skull reach in different directions.
Inhale to prepare...
Exhale and lift your right leg. Actively squeeze your bum to make the glute work.
Inhale lower the leg with control. No plopping the leg down.
Repeat switching legs so you lift the leg. Repeat each side 3 - 4 more times.
Do relax your back after this in a child's pose or downward dog.
