Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Start by lying on your back with knees bent and feet flat. Lift your head and shoulders off the floor, bracing your abs, then rotate your torso to one side, reaching your hand towards your heel. Return to the center and repeat on the opposite side, alternating sides throughout the exercise.
Prioritize controlled movements and feel the contraction in your abdominal muscles. Gradually increase the challenge by adding pauses or resistance. Ensure you're moving through the complete range of motion on each side. Maintain a neutral spine throughout the exercise to avoid lower back strain. Breathe deeply and consistently to support core engagement.
