Starting 3 days a week with my trainer. I really need to work on my chest.

1. Depends on how old you are, at least from my experiences...

From 0 to about 25, your body, if you exercise it, seems to be working with you and you get very quick tone, strength, and stamina gains depending on how you're working out. By 30 or 35, you are starting to have to expend more time and effort to maintain the same results, and by 40 you start to realize that your body seems to be working against you.

By 40 it is very difficult to maintain the kind of work it takes to stay truly fit (if you aren't one of those people who can just eat anything and stay skinny... feckin' bastids') without some sort of outside help. Getting a trainer should certainly help to keep your motivation up and keep you concentrated on exercises which will maximize your results. Good luck.
