Yep I hit 40 a few days ago, and i've been mtb biking for like 2 years now to stay in shape, I always had some sort of bike. so me and some friends where talking and I told them that I can run now so much faster and longer, then I could 20 years ago, so I'm at the best condition of my life, I tought.
but then when I went to sleep that night i remembered when I was 18 or so I could do like 100 to 150 pushup straight with no problem, now I can barely do 50 my arm start to hurt so bad, so something must be missing form my system, I got me thinking, if i had that vigor i had 20 years ago I would be so much faster on the bike, so my question, what gave me that vigor back then, more test, more hormones or hgh ?
