Barbell Jefferson Squat
Description
The barbell Jefferson squat (Jefferson lift) is an old-school squat where you straddle the barbell — one foot in front, one behind, with the bar between your legs. You grip the bar with a mixed grip (one hand front, one back) and stand up. It builds asymmetric core strength and unique leg loading.

Barbell Jefferson Squat Instructions
- Place a barbell on the floor. Straddle the bar — your right foot on one side, left foot on the other side, bar between your legs.
- Place your right foot slightly forward, left foot slightly back, in a staggered straddle.
- Squat down. Grip the bar with a mixed grip — left hand in front of your body, right hand behind.
- Drive through your feet to stand up. Pull the bar between your legs.
- Lock out at the top.
- Lower back down with control.
- Switch foot positions and grip for the next set to balance loading.
- Use moderate weight — the asymmetric load is challenging.
