Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Stand with feet hip-width apart, holding a kettlebell in one or both hands. Engage your core, keep your chest up. Step back with one leg, lowering hips to 90-degree knee bend. Front knee over ankle, back knee hovering. Push through the front heel to return to start. Alternate legs.
Maintain upright posture. Engage your core for balance. Prevent front knee from extending past toes. Use controlled movements. Start with a lighter weight to master form.
