Jefferson Squat

Move · Resistance Training · Movement, Typed Supps

With the bar between your legs, one hip is in front of it and one behind, so the load tries to twist you as you stand.

Stage by stage

Set-up (Straddled, split stance): One foot ahead of the bar and one behind, with the hands split fore and aft.
During the lift (Rotation, not flexion): The load sits inside the base, so the spine sees less flexion torque while the obliques see rotation.
Between sides (Stances are not equal): One stance is usually markedly stronger, so the weaker side sets the working load.
Months later (Trunk and hip control): Anti-rotation strength through the obliques and hips builds alongside ordinary leg strength.

Muscles trained

Primary: glutes, quads
Secondary: adductors, lower back

Intensity

6 METs (Resistance training (weight lifting, free weight, nautilus or universal), power lifting or body building, vigorous effort (Taylor Code 210)).

Time to effect

Weeks: The asymmetric stance usually feels genuinely strange for the first several sessions — expect more focus on staying balanced and square than on the weight itself while your body learns the unfamiliar straddle position.
Months: Over 2 to 3 months, the oblique and hip stability built from resisting the bar's twisting tendency tends to carry over into more general trunk control, alongside straightforward strength gains in the legs and hips.

Common myth

"The Jefferson squat is just a deadlift with your feet in a weird position." In reality: The straddled stance changes the lift more than that description suggests. Because one leg is forward and one is back with the bar between them, the load is asymmetric side to side, which demands real anti-rotation strength from the obliques and hips to keep the bar path straight, a demand a conventional deadlift, symmetric front to back, doesn't create.
