Muscle outlines from Body Muscles by Ivan Vulović, Apache 2.0 — regrouped and recoloured for Muscle Train.
Lie on your back with knees bent and feet flat, fingers lightly placed behind your head. Inhale to prepare, then crunch upwards, rotating your torso to bring your elbow toward the opposite knee. Alternate sides with each repetition, focusing on controlled movements and engaging your obliques.
Execute each movement deliberately to enhance muscle activation. Maintain consistent contact between your lower back and the floor. Position your fingertips gently behind your head to safeguard your neck. Avoid any forward pulling on your neck during the exercise.
