Answer :
Lifting heavier weights promoted muscle hypertrophy which leads to an increase in the size of the muscles.
An increase in muscle mass is known to as muscular hypertrophy. Typically, this results in a growth in muscle mass and strength. Muscle hypertrophy typically results from strength training, which is why weight lifting is frequently related to it.
People who lift weights can increase their muscular mass through sarcoplasmic and myofibrillar hypertrophy.
This involves working out against resistance that progressively gets stronger over time. This puts stress on the muscles, damaging the fibers, which the body then heals.
When the muscles are repeatedly challenged in this manner, they adapt by developing in size and strength. People may enhance muscular growth by focusing on strength training, a variety of activities, and obtaining enough sleep.
