How to do it:
Start standing with your knees slightly bent, with your hands on your buttocks. Push your hips forward and tighten both your glutes and abdominal muscles at the same time (thrusting forward with your hips), and then release. Repeat 8 times.
How it will heat things up: This move strengthens "thrusting" muscles in the lower back, hips, and lower abs, Anderson says. "Strong muscles create strong thrusting and, well, we all know how good it feels to thrust!"
