Check out all the variations of the rockit drill. This exercise is awesome for hip stability, core stability and strength, as well as endurance and fatloss.
It's an exercise that most people have never even heard of that burns tons of calories, and fat. It's part of Scott Sonnon's Circular Strength Training program and is typically performed with clubbells but can be modified for other equipment i.e. sandbell, sandbag, kettlebell-medicine ball, and even a dumbbell.
When done correctly it targets your glutes, hips, and core and feels like you're doing cardio. Watch the video for tips on how to perform this exercise. For more clubbell exercises check out The Big Book of Clubbell Training
