This week's exercise is the Weighted Ankle Crossover. For this exercise you will need ankle weights (I am using 2.5lb weights here). Start by getting on all fours with your forearms on the floor and knees about a foot behind your hips and straighten your right leg. Brace your core (abs) and glutes as you lift your right leg over to your left leg, tapping your right toe on your left foot. Return back to the beginning and repeat. I did a few reps here, I would start by doing 5 reps (you will definitely feel it in your legs and glutes) and then switch to the left leg.
