Everyone that trains at some point has done or still does pushups to some degree. The problem is most people really do not work very hard at getting better at pushups. Pushups are usually done to warm up or cool down at the end of a workout.
A lot of people do not give the pushup a lot of respect and for what it can and will do for the body. I know that I have done well over a million pushups in my over thirty years of training. In those thirty years of training and doing pushups I would always try and figure out the best way to improve the number of pushups I could do.
I tried every possible way of trying to increase my numbers and there was never any type of information on improving the number of pushups. I thought and tried to figure it out. One way I thought of increasing the number was to do a lot of bench pressing at the time I thought it was almost the same movement and of course I found something could be farther from the truth.
So bench pressing did not help me. I figured I needed to improve my endurance because doing pushups got me breathing heavy to fast which slowed me down. Distance running did not help me.
The first time I did a lot of pushups in one workout was when I was a senior in high school when I did 1,200 pushups in 1 hour. But I still could not figure out how I should train for improving my pushups, including doing pushups.
Then I got talked up to the experts talking about resting and letting the body rest and do not over train no wonder I was not getting any better, it was because I was not doing enough.
The two secrets that changed the number of pushups I could do was having a functionally stronger body and training with short intestinal exercises like sprints, jumping rope, burpees etc.
Training this way allowed my body to get used to training without oxygen (anaerobic) not with oxygen (aerobic). Weight training and distance running requires training the anaerobic system. Sprints, jumping rope, burpees, pushups require training the anaerobic system to really excel.
Men in Military, state police, mixed martial arts and martial arts have all benefited from this type of training for improving their pushups.
Training fast and explosive will strengthen your body and give you the strength and conditioning to improve your pushup numbers farther than you ever thought possible.
