Doreen,
I am fifty...turned last week. What I have noticed is that to build fitness level is difficult and overtraining is more apparent. I had minor surgery (major to me it was bladder cancer, but nothing was "cut"). I couldn't workout for nearly a month or I had bleeding. Then when I started again, it took quite a bit to get anyway near my routine.
Also I keep things varied now. Two much of anything and I end up with knee, hip, or toe pain. So high impact is no more than once a week.
But the biggest issue for my fitness level now...is how much I need my sleep. one late nights and I am hindered horribly in my workouts. So much for my all nighters in my twenties, and thirties and going for a run the next day!
