Thrusters can be completed with either barbell (as in video), dumbbells, medicine ball, or kettlebells. It's a taxing exercise because it's a front squat combined with a standing overhead press. It also demands the participant builds a solid core/midline to balance the weight at all phases of the movement. Thrusters are a building-block for fitness in my regiment. If you are not doing them, start. If you're already doing them, do more!
