So I cannot wait to share it with you guys. All right, onto the floor where most of the magic happens, one of my other favorite exercises is the Russian Twist. A modification, if you’re new to this, not so strong, just keep your heels on the floor, lean back slightly. If you are a more advanced exerciser you can bring your legs up and cross them but I’m going to show the modified version for now. Take your medicine ball, lean back, you should already feel the contraction in the abs, and then you’re just going to tap the ball from side to side. If you’re feeling adventurous, bring the legs up for a greater burn. You could do 3 sets of 30 to 40 of those, they’re pretty quick but you should feel a nice burn.
