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 Bulgarian Bag over your shoulders. Step forward with one foot, lowering hips until knees are bent at 90 degrees. Front knee over ankle, back knee hovering. Push through the front heel to rise, bringing the back foot forward into the next lunge. Alternate legs, maintaining an upright torso.
Engage your core for balance. Control the movement, avoid rushing. Keep your front knee behind your toes. Choose a challenging but manageable weight. Breathe consistently: inhale on the descent, exhale on the push-up. Start with a lighter bag to master form.
