Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Engage your core, pressing your lower back into the floor. Lift legs and upper body, bringing the dumbbell towards your shins. Balance on your glutes at the top, forming a V shape. Lower with control, keeping heels and the dumbbell just off the floor.
Focus on keeping your ribs down throughout the exercise to protect your lower back and enhance core stability. Actively squeeze your abdominal muscles to maintain a strong brace and control the movement. Lower your torso and legs with deliberate control, resisting the urge to drop quickly, to maximize muscle engagement and prevent injury. Maintain straight arms throughout the movement to isolate the core and glutes, avoiding unnecessary shoulder involvement.
