Açıklama
Jackknife Sit-up or V-Up is a dynamic exercise that works all abdominal muscles simultaneously. It targets the core region comprehensively by using the upper and lower abdominal muscles in a synchronized manner. It is known by this name because the body forms a 'V' shape during the movement and is visually impressive. It develops functional strength by working the rectus abdominis, obliques, and hip flexors together. It is frequently included in calisthenics and bodybuilding programs and has a moderate to advanced difficulty level. When performed with proper form, it protects lower back health while developing strong and aesthetic abdominal muscles.
