This is a great exercise to isolate your quads a bit differently than your traditional sissy squat and leg extension. As you perform the exercise you will also be engaging your glutes, hamstrings, lower back, and traps. Your calves and spine erectors will be engaged as well to help you stabilize your body throughout the exercise.
If you are having a hard time with this exercise, it could be due inflexibility of your hips. As you perform the Jefferson Squat, alternate which hand is grabbing the bar in front of your body to bring out any inflexibility you might have. For me, I seem to have a harder time with my left arm in front of my body.
The only way you can improve is to see what needs improvement! #HTH #SHFAthelte
