Barbell Single Leg Split Squat: How to Do It & Muscles Worked

The barbell single leg split squat is a lower body exercise that targets the quadriceps while also engaging the glutes, hamstrings, and calves. It requires balance, coordination, and strength, as you perform a squat movement with one leg forward and a barbell across your upper back.

How to do the barbell single leg split squat

  1. Step 1: Stand with your feet shoulder-width apart, holding a barbell across your upper back.
  2. Step 2: Take a large step forward with one leg, keeping your torso upright.
  3. Step 3: Lower your body by bending your front knee and hip, while keeping your back leg straight.
  4. Step 4: Continue lowering until your front thigh is parallel to the ground.
  5. Step 5: Pause for a moment, then push through your front heel to return to the starting position.
  6. Step 6: Repeat for the desired number of repetitions, then switch legs.

Sets, reps and programming

Suggested sets, reps and rest for the barbell single leg split squat by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
