Re: how do you PT to stay in shape?
"Pain is weakness leaving the body."
The above has become my mantra, and I've I got a shirt that says that as well. Learn it, live it, understand it, make it work for you.
Physical fitness don't get no easier as you get older. I'm on the north side of 50 myself, but I'm still going strong, and the aches and pains seem to increase the older you get. But, I'll never give up until they put me in the ground, and neither should you!
I run. I like a few races thrown into my training schedule during the year just to shake up the regular excercise routine and keep things from getting boring. One or two 1/2 marathon road races each year is about right for me (YMMV, I didn't start until I was in my mid-30's). Also, some gym time with weights when I'm not training for long distance runs. Learn what your own body likes and can handle, as we are not all built the same and we don't all respond to PT the same.
We all need to do a little soul searching, if we haven't already, and ensure we make PT a part of our lives and work it into our life style. Excercise really can help you lead a better and happier life. Remember that we each get only one body to make the trip with. Also, the rewards are not only physical as PT is good for the mind too. And don't forget to set a good example and get the whole family involved! It's all good, now make it happen and enjoy the rewards!!!
