I'm a 67-year-old woman in fairly decent condition. I have been doing the Strong Women program at a gym with a fitness trainer. I have found that I am quite fatigued the day after a session, enough to need a short nap. My muscles have been pretty sore the next day also. I have reduced the weight on the various machines. I have increased the time between sessions to two days. Do you think my body, my muscles, will gradually adjust or do you have any further suggestions. I am enjoying the fitness sessions on the machines and would not want to give up.

It's wonderful that you're enjoying the sessions despite the aftereffects! But you really shouldn't be suffering so much. It sounds as if your body has announced that you were overdoing the exercise. I think you were wise to increase the time between sessions and to reduce the weight on the machines. If you continue to experience pain and fatigue, I suggest you cut back further on the weight and then increase gradually.
