Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Extend your hip and knee by driving through your lead heel. Fully straighten the lead leg and lift your body. Bring your trailing foot to tap the box or hover near the lead foot. Lower under control, softly touching the floor with the trailing foot.
To maximize power and stability, focus on driving forcefully through the heel of your lead foot, which will help engage your glutes and quads. Maintain an upright chest throughout the movement to prevent leaning forward and ensure proper balance and core engagement. Control the descent by resisting the urge to drop quickly, engaging your leg muscles to manage the impact and protect your joints. Avoid pushing off your back leg, as this reduces the effectiveness of the lead leg's work and can disrupt your balance; instead, let it act as a stabilizer. Ensure your lead knee tracks directly over your toes during the extension phase to promote efficient movement and minimize stress on your knee joint.
