How to do the 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
The prime movers are the quadriceps across the front of the thigh, which straighten the knee and, just as importantly, control it on the way back down.
Because more than one joint is moving, the work does not stay in one place: the calves control the ankle and hold the heel position; the glutes finish hip extension; the hamstrings assist hip extension and slow the knee down.
The lower back and traps take a share of the work as well.

How this movement works
The working muscles shorten as they drive the load away from you, and more than one joint changes angle to do it. Load spreads down a chain instead of sitting on one muscle, which is why a compound push handles more weight than any single-joint alternative — and why joint position, not the muscle, is usually what fails first.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
A barbell locks both hands to one bar, so neither side can drift and the load climbs in plate-sized steps. That makes it the simplest way to add weight and the least forgiving thing to bail out of.

Difficulty
Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
