 Lunge Jumps

Instructions: Stand with your right foot forward, left foot back in a tall lunge position. Lower into a lunge, bending both knees to 90 degrees. Push strongly through your feet, jumping into the air and switching your feet before you land. Your left foot should now be forward, and the right one should be back. Land softly until a lunge position, and immediately jump back into the air to switch your feet. Use your arms to help you get height.

When your legs start to burn and the lunge jumps get challenging, mix in some walking lunges.
