Most trainers typically do 3-4 sets of an exercise, but with chins Arnold commonly used a technique in which he aimed for a total number of reps—say, 50—rather than target a particular number of sets: "On the first set you may do 10 reps. Perhaps you struggle with 8 reps on the second set. You have 18 reps now. If you make 5 on the third set, you have 23 reps. You continue to add them until you've reached 50, even though it may take you 20 sets to do it. That's how I built up my chinning power, and I was very successful with it."
Our body needs a breather. When we rest or when we sleep is the time when our body conducts a synthesis of proteins, that is, the breakdown of proteins which results in the reconstructive process of muscle building and repair. Regular and adequate rest is needed in order to gain muscle. Also, metabolism takes place during the night when we sleep, and fat is burned during this process as well. This makes sleep the most effective tool when it comes to fitness and health, and we must give our mind and body 48 hours of rest before hitting the gym again, as this is the optimum time for muscle recovery.
For Arnold, building a big chest started with training for strength since he competed as a powerlifter early in his career. With a foundation of strength, Arnold discovered that gains in size came easier. Consider an offseason powerlifting cycle to help boost all your numbers before shifting back into bodybuilding-style training. For the record, Arnold once benched 225 pounds for 60 reps!
