Stepping out to one side, squatting over that leg, then pushing back to center keeps the bar moving side to side without a rest between reps. The rhythm suits moderate weight and higher reps that accumulate volume for the inner thighs and glutes, with gentler depth demands than the Barbell Cossack Squat.
How to do the Barbell Side to Side Squat
- Stand with your feet wider than shoulder-width apart, toes pointing slightly outwards.
- Hold a barbell across your upper back, resting it on your shoulders.
- Take a big step to the side with your right foot, keeping your left foot planted.
- Bend your right knee and lower your body down into a squat position, keeping your chest up and your back straight.
- Push through your right heel to return to the starting position.
- Repeat on the other side, stepping out with your left foot.
- Continue alternating sides for the desired number of repetitions.
Tip: Keep most of the weight in the front foot and think of pushing the floor away rather than standing up.
Muscles worked
Primary
Quads · Legs
The front quad controls the descent and drives you back up, and it takes an especially heavy load on split squats where the stance is fixed.
Secondary
- Glutes — The glute of the front leg extends the hip, and leaning the torso forward slightly with a longer stride shifts more work onto it.
- Hamstrings — The hamstrings of the front leg assist the glutes in hip extension and control the knee on the way down.
- Calves
Common mistakes
- Front knee caving inward — the knee should track over the second toe; if it drops in, widen the stance slightly and push the knee out.
- Stepping too short — a short stride pushes the knee far past the toes and shifts everything onto the quad and knee; lengthen the step so the shin stays fairly upright.
- Leaning forward and rounding — keep the torso tall and the chest up, and let the back knee drop straight down rather than reaching forward.
- Pushing off the back foot — drive back up through the front heel; the back leg is just there for balance.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 4–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 6–12 | 90–120 s |
| Endurance | 2–3 × 12–20 | 60 s |
Lunges and split squats go after squats or deadlifts as the main single leg movement, or first on a lighter day. Superset them with a Romanian deadlift using the same dumbbells for a complete lower body pair.

Is the Barbell Side to Side Squat good for beginners?

What can I do instead of the Barbell Side to Side Squat?
If you cannot do the Barbell Side to Side Squat, try the Suspension Bulgarian Split Squat, the Split Squat or the Dumbbell Bulgarian Split Squat. Each of them trains the quads through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Barbell Side to Side Squat, a sensible starting point is strength: 4–5 × 3–6 with 2–3 min rest; muscle growth: 3–4 × 6–12 with 90–120 s rest; endurance: 2–3 × 12–20 with 60 s rest. Put it early in the session while you are fresh, before isolation work for the same muscles.
