How to perform Barbell Back Squat
- Set the bar across your upper back and unrack it.
- Stand with feet shoulder-width and toes slightly out.
- Sit back and down until your thighs are at least parallel.
- Drive through your mid-foot to stand back up.
Muscles worked
- Quads (primary): extends the knee to drive squats, lunges and jumps.
- Glutes (secondary): extends and stabilises the hip — the engine behind hinges, squats and sprints.
- Hamstrings (secondary): bends the knee and extends the hip through hinges and pulls.
- Core (secondary): braces the trunk and resists twisting to protect the spine.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the knees tracking in line with the toes and push the whole foot into the floor.
- Keep the bar path close and stacked over your mid-foot; letting it drift forward wastes force and loads the lower back.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Letting the knees cave inward as you push out of the bottom.
- Loading the bar heavier than your form allows and turning strict reps into a whole-body heave.
- Chasing weight jumps before the current load feels solid on every rep.
