Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Engage your core, rotate your torso to one side, rolling your shoulder towards the ball while stabilizing your hips. Briefly hold the twist, contracting your obliques, then return to center with control. Alternate sides.
To maximize oblique engagement, initiate the movement by consciously drawing your obliques towards each other as you begin the rotation. Focus on keeping your hips stable throughout the exercise to prevent unwanted rocking or shifting, which would reduce the effectiveness of the twist. Maintain a straight line from your head to your heels while on the ball to ensure proper spinal alignment and prevent lower back strain. Control the rotation throughout the entire range of motion, avoiding jerky movements to protect your spine and fully engage your core muscles. Remember to brace your core consistently throughout the exercise to maintain stability and protect your lower back.
