Jefferson Squat

Straddling the bar with one foot forward and one back and gripping it between the legs creates an offset, anti-rotational load that trains the quads and glutes while the trunk fights hard to resist twisting. The unusual stance builds strength through a range and in a plane most squats never touch, making it a favorite of odd-object and old-school strength enthusiasts. It is technically demanding, so learn it light and alternate stances to keep both sides even.

How to do it

  1. 1

    Straddle a loaded barbell so it runs between your legs, with one foot forward and one back.

  2. 2

    Take a mixed grip on the bar, one hand in front of the body and one behind, and set the back flat.

  3. 3

    Brace hard and resist the tendency to twist toward the offset load.

  4. 4

    Drive through both feet to stand the bar up, keeping it traveling in a straight vertical line.

  5. 5

    Lower under control back toward the floor while holding the anti-rotation brace.

  6. 6

    Complete your reps, then switch which foot leads to balance the two sides.

Tips

  • Fight the rotation the whole rep; the offset bar constantly tries to turn your hips and shoulders.
  • Keep the spine neutral and braced, and start light while you learn the awkward path.
  • Alternate the leading leg across sets so one side does not get all the work.

Variations

Common mistakes

  • The hips shoot toward the rear leg as the bar leaves the floor, turning what should be a vertical pull into a twisting lift through the lower back.
  • Gripping too narrow on the bar with the hands close together removes the leverage that helps resist rotation, so the shoulders open up mid-rep.
  • The leading foot rarely gets switched often enough, so one hip and shoulder end up doing most of the anti-rotation work while the other side lags.
  • The front knee drifts inward as the bar passes it, since the straddle stance narrows the base right where the load is heaviest.
  • A rounded lower back during the pull turns what should be an anti-rotation drill into a spinal-flexion lift, the opposite of the intent.

Frequently asked

What is a sensible starting dose for the Jefferson squat, and what should you master first?
Start light, in the range of 3 sets of 5 reps per side with a weight you could do for 10, since the offset stance and anti-rotation demand matter more than load here. You should already be comfortable bracing against rotation, from something like a suitcase carry or a heavy single-arm row, before you load this one seriously.
What can you do instead of the Jefferson squat without a barbell?
A heavy dumbbell or kettlebell straddled between the feet and gripped with both hands reproduces the same offset, anti-rotation pull on a smaller scale. If you have neither, a suitcase deadlift with a single dumbbell trains resistance to side-bending instead, a close relative of the anti-rotation demand, minus the straddled stance.
What is the Jefferson squat good for, and who should avoid it?
It builds anti-rotation strength and works the quads and glutes through a stance most squats never touch, which appeals to lifters chasing odd-object and old-school strength work. It is a poor choice for anyone new to lifting or anyone with a cranky lower back, since the technical demand and the twisting load are both high before you have the bracing to control them.
