How to perform Chair Squat
- To begin, first set the bar to a position that best matches your height. Once the bar is loaded, step under it and position it across the back of your shoulders.
- Take the bar with your hands facing forward, unlock it and lift it off the rack by extending your legs.
- Move your feet forward about 18 inches in front of the bar. Position your legs using a shoulder width stance with the toes slightly pointed out. Look forward at all times and maintain a neutral or slightly arched spine. This will be your starting position.
- Slowly lower the bar by bending the knees as you maintain a straight posture with the head up. Continue down until the angle between the upper and lower leg breaks 90 degrees.
- Begin to raise the bar as you exhale by pushing the floor with the heels of your feet, extending the knees and returning to the starting position.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Quads (primary): extends the knee to drive squats, lunges and jumps.
- Calves (secondary): points the foot to power push-off and steady the ankle.
- 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.
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 |
Bodyweight movement: once you own the top of a rep range, progress by slowing the tempo, pausing at the hardest point, or moving to a harder variation instead of adding load.
Form tips
- Keep the knees tracking in line with the toes and push the whole foot into the floor.
- Own the largest range you can control with clean form before you chase extra reps.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Letting the knees cave inward as you push out of the bottom.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Chasing weight jumps before the current load feels solid on every rep.
