Instructions

1

Start in a plank position with hands shoulder-width apart, body in a straight line from head to heels, core engaged, and one knee tucked toward the chest

2

Keep your supporting leg extended behind you with the foot on the ground, maintain a neutral spine, and stabilize through your upper body

3

Slowly extend the tucked leg straight back and upward while maintaining plank alignment, allowing the quadriceps to lengthen under control

4

Drive the extended leg back to the starting position with the knee tucked toward the chest, engaging the quadriceps concentrically to complete one repetition

PRIMARY MUSCLESQuadriceps

SECONDARY MUSCLESGluteus Maximus, Hamstrings, Hip Flexors, Core Stabilizers

DIFFICULTYIntermediate

Overview

If you want to isolate and overload the Quadriceps, the Kneeling Leg Half Circle is an excellent addition to your routine. The mechanics of this Strength, Stretching exercise specifically bias the Hips, while the use of Body weight allows for a smooth, natural resistance curve.

Benefits

Promotes balanced muscular development by effectively recruiting the Quadriceps and associated synergists.
Acts as a highly scalable Strength, Stretching movement, perfect for both beginners and elite athletes.
Significantly enhances the structural integrity and power of the Quadriceps.
Improves overall Hips stability and proprioception during heavy loads.

Common Mistakes

Using excessive momentum to swing the Body weight rather than controlling the eccentric phase.
Rushing the repetition tempo instead of focusing on the mind-muscle connection with the Hips.
Losing core tension, leading to poor spinal alignment and reduced power output.
Shrugging the shoulders or compensating with secondary muscles rather than isolating the Quadriceps.

Pro Tips

If you feel this primarily in your joints rather than the Quadriceps, instantly lower the weight and readjust your Body weight setup.
