Bulgarian Lunge: Also known as the Bulgarian Split Squat. We like to think of this more as a lunge because the concept of keeping the front knee directly above the ankle is specific to the lunge movement. Push your hips back, bringing your back knee as close to the ground as you can get it. If you find it difficult to lay your elevated foot flat on the bench behind you, you can curl your toes under. This makes the movement easier on your ankle, but limits your range of motion. You can do this exercise with no weight or increase the difficulty by holding dumbbells on either side, or balancing a barbell across your shoulders.
