Box Step-Up
A foundational plyometric exercise to enhance lower body power and improve tendon stiffness, with an emphasis on controlled landing mechanics.
A foundational plyometric exercise to enhance lower body power and improve tendon stiffness, with an emphasis on controlled landing mechanics.
Plyometrics, Strength and Conditioning · Developed within sports performance and rehabilitation settings, popularized in strength and conditioning. · To improve reactive strength, develop lower body power, and increase tendon resilience and stiffness for enhanced athletic performance and injury prevention. · 3-5 sets of 6-10 repetitions per leg. Focus on quality of movement and controlled landings over quantity. Perform 1-2 times per week on non-consecutive days.
Why it works
The Box Step-Up unilaterally loads the limb, engaging the stretch-shortening cycle to enhance muscle power output. The concentric phase builds strength, while the controlled eccentric landing, when performed correctly, trains the tendons to absorb and release energy efficiently. This cyclical loading improves collagen fiber alignment and density, increasing tendon stiffness and its capacity to store and return elastic energy, thereby reducing injury risk and improving force transmission.
How to practice
Selection: Choose a box height that allows for a challenging yet controlled step-up. The knee of the stepping leg should ideally form a 90-degree angle or slightly greater when the foot is fully on the box.
Starting Position: Stand facing the box, approximately 6-12 inches away. Place one foot flat on the center of the box, ensuring the entire sole of the foot is in contact.
Initiation: Drive through the heel and midfoot of the elevated leg, using the gluteal and quadriceps muscles to step up onto the box. Maintain an upright torso and tight core throughout the movement.
Peak Contraction: Fully extend the hip and knee of the stepping leg at the top of the movement, bringing the trail leg to meet the lead leg on the box, or hovering it just off the box for an increased challenge.
Descent: Control the descent by slowly lowering the trail leg first, then the lead leg, back to the starting position. The eccentric phase should be deliberate, not a free fall.
Alternation: Alternate lead legs with each repetition, or complete all repetitions on one side before switching.
