On another thread a while back I asked a question and gave my opinion. I have to admit I did not always have this opinion. At times I was hard headed about it. But John P's response was kind of funny and I couldn't have said it better myself.
Here was the question and John's response:
" After a certain amount of years of training can we really get any bigger? Can we gain muscular size? Will Our body look any differant? My opinion, I don't think a natural person can build more muscle or get bigger without gaining fat. After so many years of training and being older I believe You probably reached what You're going to be able to do genetically. "
As much as it pains me to admit, this has been my experience as well, at least as far as increasing muscle size goes. That being said, I have also found that losing body fat and increasing muscle tone can have a fairly dramatic effect on improving one's muscular development. At 40 years old, I look more muscular now than I did when I was younger, yet am much smaller in size (and not as cute).
My father is 74 years old and has been working out since he was 14. He recently dropped 20 lbs. (intentionally) and even though he lost over 1/2" on his arms, he looks more muscular.
So why do we do this? Why should we even bother? The reason I do what I do is it's fun and relaxing. It may sound funny to some. But coming from where I was with all the pain it makes much sense to me. My 20-40 minutes( depending on what I'm doing) in the morning is like meditation from the everyday grind.
I do what I want. I experiment with differant things because I find it to be fun. I do tend to go back to and stick to things I find that works for me. Yeah I do sets, reps, ect.... but I find it fun. Honestly since I experimented so much I've found things that have keep work injuries almost to zero. So how would You answer these questions?
Just I feel much better after my self-resistance exercises. If I skip them, I feel as a piece of garbage all day.
