Push ups

As a Marine when I was 18 I could do push ups forever.. In fact the day I was graduating bootcamp I told my drill instructor I could do push ups forever and he said show me,,well I got down and started oneever twoever threeever fourever,, "sir push ups forever" He laughed his *kitten* off.. Well a about 8 months ago I struggled to do 10 in a row granted when I was 18 I was not pushing 250 lbs off of the deck. Fast forward to 8 months later I can do push ups like they are going out of style. Can I do more yes and I will!!!! Thank you Marine Corps!!!!!!!!
