I am 40 and I started training 20yrs ago. I had periods of time that I was busy with life and took off the iron but always came back. Now my wife and oldest daughter have become involved with it also. Im sure the other kids will in a few years when they are old enough.
I do not heal like I used to but I am alot smarter now. I think your weight depends on your genetics and natural structure. My last meet I bulked to 343. Right now I am about 310 and feel alot better. Im not sweating 24/7. Right now is the first time in my life I haver ever seen my abs at all. It is the leanest I have ever been which is a great feeling.
