Booty Busting Series--Best Exercises to Build that Butt #19: Lunge Jumps

Also called "Lunge Switches", Lunge Jumps are a great exercise to help you improve your leg strength without all of the aches and pains that come with lunges. You're in a sort of static lunge position that reduces the strain on your knees, but the fact that you're jumping and switching legs makes it a GREAT exercise. To add intensity to the workout, do what Tony Horton does in P90X and raise your arms straight over your head. It's harder to balance and adds a bit of extra weight to the movement, making it just that much more difficult. [caption id="" align="aligncenter" width="800"] Source: womenshealthmag.com[/caption]

Lunge Jumps

Stand with a straight back, your arms by your side, and your feet spread shoulder width apart. Step your right foot forward into a lunge, and drop your left knee to assume the proper position. Use both legs to propel you off the ground, and switch feet in the air (left foot now forward, right foot back). Hold the position for a 1-count, then jump and switch feet again. Repeat as desired.
