How long do you give your muscles to rest before you start exercising again? I don’t know if I am not stretching enough (although I try to stretch before as well as after my treadmill exercise) but lately, my thighs are really very sore. I do my treadmill exercise every other day, so the last time I was on treadmill was Saturday around lunch time. My thighs were tight beforehand and it got a lot worse afterwards. I applied some muscle-pain-relieving lotion (Myoflex?) on Saturday and last night, and it is much better today, but I am not sure if it is enough to get back on the treadmill again (and I really want to).
As if that was not enough, my shoulders are killing me from my core exercise class (with a stability ball) on Saturday so going to the gym for some weight training is not a good idea either.

Ah, the challenges of old age!!!!
