There seems to be a trend going on here, I too joined a gym just this week. I have been going in the mornings. I can only do about 45 minutes on the treadmill right now. I tried these machines that looked like backwards elliptical, I should have known better - I could only do about 6 minutes, total. Then, I tucked my tail in and went back to the treadmill. Tomorrow, I am going to give my bad joints a rest and use the recumbent bike with the senior crowd.
Not too worried about not being able to hang with everyone, I am really not in shape. It's not the first time I have exercised for multiple days, but the first time that I can see myself doing it for long term. Even before, I never truly believed that I would keep it up. Since I am doing it in the morning, it isn't delaying my life at all - making me more tired in the evenings, maybe, but that's about it. And since I am trying to stay in at the same time, I think it all works out well
Hope you don't mind me joining the thread Monster!
