Straddling the bar with a staggered stance loads each side of the body asymmetrically, so your trunk resists rotation while the legs squat - something no conventional squat variation asks for. Alternate which foot leads from set to set, keep loads modest, and give the unusual bar path a few sessions before judging it.
How to do the Barbell Jefferson Squat
- Stand with your feet shoulder-width apart and toes slightly turned out.
- Hold the barbell with an overhand grip, resting it on the front of your body, just below your waist.
- Step your left foot forward and your right foot back, keeping your feet shoulder-width apart.
- Bend your knees and lower your body down into a squat position, keeping your back straight and chest up.
- Push through your heels to stand back up to the starting position.
- Repeat the movement, alternating your forward and back foot with each repetition.
Tip: Screw the feet into the floor and spread it apart to keep the knees out and the arch of the foot from collapsing.
Muscles worked
Primary
Glutes · Legs
The glutes extend the hip on the way up and take more of the load the deeper you go and the wider your stance.
Secondary
- Quads — The quads extend the knee and drive you out of the bottom, and front squats and close stance variations put more on them.
- Hamstrings
- Calves
Common mistakes
- Knees caving inward — push the knees out over the toes on the way up, especially out of the bottom where they most want to collapse.
- Hips shooting up first — if the hips rise faster than the chest on the way up, you turn the squat into a good morning; drive the chest and hips up together.
- Cutting the depth — get the hip crease below the top of the knee on every rep unless mobility genuinely stops you, in which case work on it.
- Losing the brace — take a big breath into the belly before each rep and hold it through the sticking point, then exhale on the way up.
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 |
Squats go first in a lower body session when you are freshest. Follow them with Romanian deadlifts or leg press, or superset lighter sets with pull-ups to use the same rack.

Frequently asked questions
What muscles does the Barbell Jefferson Squat work?
The Barbell Jefferson Squat primarily works the glutes. It also involves the quads, hamstrings and calves, which assist the movement and stabilise the joints.
Is the Barbell Jefferson Squat good for beginners?
It is rated intermediate, so it suits people who already train regularly. Beginners can still do the Barbell Jefferson Squat with light load and a spotter or coach watching the first few sessions; if it feels awkward, pick an easier variation from the alternatives below first.
What can I do instead of the Barbell Jefferson Squat?
If you cannot do the Barbell Jefferson Squat, try the Curtsy Lunge, the Box Bulgarian Split Squat or the Supported Bodyweight Squat. Each of them trains the glutes 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 Jefferson 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.
