CHIN UP / KNEES UP (B078)

The chin-up with a knee raise is an advanced variation of a standard chin-up. It combines a vertical upper-body pull (underhand grip) with an active hanging knee raise. As you pull your chin above the bar, you simultaneously lift your knees toward your chest, locking your core to prevent swinging and building integrated upper-and-lower body strength. Key Features Dual-Target Muscle Engagement: Upper Body: Heavily targets the latissimus dorsi (lats), biceps brachii, teres major, and rhomboids due to the supinated (palms-facing-you) grip. Core & Hip Flexors: Engages the rectus abdominis, transverse abdominis, and hip flexors intensely to lift and control the weight of the legs. Anti-Swinging Stability: Because moving your legs changes your center of gravity, this movement requires supreme core rigidity to eliminate momentum or "kipping," forcing strict, muscle-driven execution. Progression Toward Advanced Skills: Acts as a vital stepping stone for more complex calisthenics movements, such as L-sit pull-ups or front levers, by teaching the body how to tension the core while hanging. Scalability & Variation: Can be modified based on fitness levels—ranging from tucking one knee at a time to lifting straight legs (toes-to-bar) combined with the pull-up.
