How to perform Weighted Squat
- Start by positioning two flat benches shoulder width apart from each other. Stand on top of them and wrap the weighted belt around your waist with the amount of weight you feel comfortable with. Make sure your toes are facing out.
- Once you are standing straight up with the weight hanging in between your legs, position your arms so that they are fully extended to the side of your body. This is the starting position.
- Begin by bending the knees as you maintain a straight posture with the head up. Continue down until the angle between the upper leg and the calves becomes slightly less than 90-degrees (which is the point in which the upper legs are below parallel to the floor). Inhale as you perform this portion of the movement. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that are perpendicular to the front. If your knees are past that imaginary line (if they are past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly.
- Begin to move the body back up by pushing the floor of the flat bench with the ball of your foot mainly as you straighten the legs again and go back to the starting position. Exhale as you perform this portion of the exercise.
- 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 |
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.
- Set the seat and pads so the machine's pivot lines up with the joint you're training before your first rep.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Letting the knees cave inward as you push out of the bottom.
- Leaving the seat or range on a setting that forces the joint into an awkward angle.
- Chasing weight jumps before the current load feels solid on every rep.
