Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Begin seated with your legs straight and toes flexed upward. Position your hands flat on the floor, palms down, then extend your arms outwards. Squeeze your glutes and lift your hips to create a straight line from your head to your heels, maintaining a plank.
Ensure your spine remains level by aligning your shoulders, hips, and knees. Pause and rest if your hips sag during the exercise. Extend your arms fully to reduce strain.
