It’s the force placed on the muscle fibers during stretching and contracting. Bodyweight exercises, especially when performed with correct form and sufficient intensity, create ample mechanical tension. 2. Muscle Damage: Micro-tears in muscle fibers lead to a repair process that makes the muscle grow back stronger and larger. The eccentric (lowering) phase of bodyweight exercises is excellent for inducing muscle damage. 3. Metabolic Stress: The accumulation of byproducts (like lactate) during high-repetition sets, often causing that "pump" feeling. This stress stimulates hormonal responses and cell swelling, contributing to growth. Crucially, you don't need heavy external loads to achieve these.
