Burn up to 400 calories in 20 minutes: That's what you'll get from a kettlebell workout.
A kettlebell looks like a cast-iron cannonball with a handle on top. They come in various weights. You'll use them as you do things like lunges, lifts, and shoulder presses. The workout gets your heart pumping and uses up to 20 calories per minute: about as much as running a 6-minute mile. Kettlebell workouts offer a lot of flexibility. You can include a few of the moves in your own workout or do a dedicated kettlebell workout a few times a week.
Often thought of as a finisher or tool for your upper body, battle rope workouts utilize muscles in your glutes, back, abs and can be used to build legs with lunges, squats and jumps. Ropes can be power, strength or endurance.
