That ability to exhaust the muscle will take longer.
Eg for demonstration sake only, perhaps you take 3 sessions in the gym to move from 5lbs to 10lbs. You might take 6 sessions (much later) to move from 15lbs to 20lbs. You might take 30 sessions to move from 40lbs to 45lbs.
Basically, you're going to slow down in that ability to get to failure with good form. That will keep you from becoming The Hulk.
Also, you might move away from hulking great piles of metal and onto significantly advanced bodyweight moves. Eg one-handed pushups, hand-stand pushups, etc.
