To perform the Bulgarian Split Squat, begin standing about 3 feet in front of a bench with an overhand grip on the barbell as it rests on your upper back. Put the instep of your left foot on the bench behind you. Lower your body until your right knee becomes bent 90 degrees and your left knee comes close to touching the floor. Your torso should be upright while your right lower leg is perpendicular to the floor. Push yourself back to the original starting position as quickly as possible. Repeat with the right foot on the bench.
