Hit your quads, hamstrings, and glutes with a stationary lunge.

Directions:

1. Split your stance with your right leg in front. Your right foot should be flat on the ground, and your left foot should be up on its toes.
2. Bend your knees and lunge, stopping when your right thigh is parallel to the ground.
3. Push up through your right foot to return to the starting position. Repeat for desired number of reps, then switch legs.
