Begin on your hands and knees. Simultaneously lift your left arm up and your right leg up, making sure to keep both straight. Then, bend your left arm and your right knee and bring them in, squeezing your core tight. Repeat this movement, and then do the same on the opposite side, with your right hand forward and your left leg back. CHALLENGE YOURSELF: Hold a light weight in the arm reaching forward! This will up the anty and work your back muscles even more BUT, only do so if you’re able to keep the correct form.
