How to do a crossover lunge:
- Stand with your feet hip-width apart. Hold a single dumbbell in front of your chest, or hold one in each hand by your sides.
- Take a large step diagonally forward with your right foot, planting your foot at the 11 o'clock position. Lower until your top thigh is about parallel to the floor.
- Push off your right foot to step it back next to your left, and return to the starting position.
- Step backward and to the left at a diagonal with your right leg, this time stepping to the eight o'clock position. Lower until your top thigh is about parallel to the floor. That's one rep.
