strength training helps get more muscle by recruiting more muscle fibers depending on the amount of weight you lift .as you add weight you call upon more motor units to innervate new muscle fibers.these muscles fill with blood that is hypertrophy if not used then atrophy will happen.shrinking of the muscle.

When you bend your elbows and clench your fists these muscles bulge?

When you bend your elbows and clench your fists, the primary muscles that bulge are the biceps brachii in the upper arm and the brachialis underneath it. The biceps contract to flex the elbow and bring the forearm toward the shoulder, while the brachialis assists in this movement. Additionally, the forearm muscles, such as the flexor muscles, engage to clench the fist, contributing to the overall bulge of muscle. This coordinated action highlights the strength and function of the muscles involved in arm and hand movements.
