I have been doing push-ups for sometime now, starting 6 or 7 years ago. I haven't been too regular, but about 3 quarters of the days in these years I used to be regular. My problem is I can't do more than 20 push-ups at a time even after 2 months of regular push ups. Does it take longer to achieve a good rate of push ups at a time?
To put things in perspective, I am 24, male, a few kilos less than 100kg (around 215 pounds) and can do a total of 80 push ups a day. I have lots of fat to lose, but definitely want to exercise to lose fat and gain muscles.
