Instructions

1

Stand upright with feet hip-width apart, arms at sides or in running position. Maintain neutral spine and engage core. Head facing forward.

2

Begin with feet positioned shoulder-width apart. Prepare to drive knees upward explosively. Keep shoulders relaxed and arms ready to drive forward and backward in running motion.

3

Lower the body by bending at hips and knees, allowing one leg to drive forward while the opposite leg extends behind. The quadriceps lengthens as the knee flexes during the landing phase of each stride.

4

Drive explosively upward by extending the hips and knees, propelling the body forward and upward. Drive knees high toward chest while maintaining running form. Return to starting position with controlled landing, alternating legs in continuous running motion.

DIFFICULTYBeginner

Overview

When programming for Quadriceps growth, the Run and Semi Squat Jump stands out as a highly efficient Cardio choice. Performing this movement with Body weight forces your stabilizer muscles to work in tandem with the primary movers, translating to functional strength and enhanced muscular endurance.

Benefits

Utilizes Body weight to create sustained mechanical tension, forcing deep muscle adaptation.
Significantly enhances the structural integrity and power of the Quadriceps.
Reduces the likelihood of Cardio injuries by reinforcing connective tissue strength.
Acts as a highly scalable Cardio movement, perfect for both beginners and elite athletes.

Common Mistakes

Failing to achieve a full range of motion, which drastically limits Quadriceps engagement.
Using excessive momentum to swing the Body weight rather than controlling the eccentric phase.
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.

Muscle Anatomy

The primary driver is the Quadriceps. However, the movement also recruits Hamstrings, Gluteus Maximus, Calves, Core Stabilizers to maintain control of the Body weight.

Beginner Tips

If you are new to the Run and Semi Squat Jump , focus on mastering the movement pattern with zero weight before adding Body weight.
