How to perform Jefferson Squats
- Place a barbell on the floor.
- Stand in the middle of the bar length wise.
- Bend down by bending at the knees and keeping your back straight and grasp the front of the bar with your right hand. Your palm should be in (neutral grip) facing the left side.
- Grasp the rear of the bar with your left hand. The palm of your hand should be in neutral grip alignment (palms facing the right side). Tip: Ensure that your grip is even on the bar. Your torso should be positioned right in the middle of the bar and the distance between your torso and your right hand (which should be at the front) should be the same as the distance between your torso and your left hand (which should be to your back).
- Now stand straight up with the weight. Tip: Your feet should be shoulder width apart and your toes slightly pointed out.
- Squat down by bending at the knees and keeping your back straight until your upper thighs are parallel with the floor. Tip: Keep your back as vertical as possible with the floor and your head up. Also remember to not let your knees go past your toes. Inhale during this portion of the movement.
- Now drive yourself back up to the starting position by pushing with the feet . Tip: Keep the bar hanging at arm's length and your elbows locked with a slight bend. The arms only serve as hooks. Avoid doing any lifting with them. Do the lifting with your thighs; not your arms.
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.
- Core (secondary): braces the trunk and resists twisting to protect the spine.
- Back (secondary): pulls the arms down and toward the torso and keeps the spine stable.
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.
- Stop a rep or two short of failure on most sets to keep form clean and recover faster.
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.
