Fast exercises vs slow exercises (same weight)
I've been doing fast push-ups since about a year. Now I can make 40 push-ups at once, otherwise I make them 3 sets of about 20-21 repetitions each, with 90 seconds between the sets. I used to think that's really bad score for that much training. Besides, before I started doing them fast, I was able to make at least 40 of them, I think.
Recently, I had a talk with a friend, and he said that if I do them quickly, I'll gain much less endurance and strength, but I'll have it at a much higher speed. Is this true?
If yes, then what is the best training for MMA? Should I be quick, but weak and easy to get tired, or should I be stronger and more endurable, but slower? I haven't watched many matches, but I've seen many fighters who are fast, and yet they don't get tired quickly, I think. I am really fast, but I get tired too fast.
P.S. When I try to do slow push-ups, I still make as many as I do when I do them quickly.
