Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Brace your core, keep chest up, and lean back slightly as you drive knees forward. Rise onto tiptoes, lower your body until knees hover above the ground, and push through your toes to return upright, maintaining hip alignment.
To ensure proper knee alignment, focus on keeping your knees tracking directly over your toes throughout the movement, preventing them from collapsing inward or pushing outward. Actively brace your core muscles throughout the exercise, as this will stabilize your spine and improve power transfer. Control the torso lean backward, avoiding excessive arching or rounding, to protect your lower back and maintain balance. Keep your hips aligned with your torso to prevent lower back discomfort and ensure even weight distribution. Drive through the balls of your feet to powerfully extend your knees and fully engage your calf muscles, maximizing the effectiveness of the exercise.
