I hear ya. I haven't been riding my bike as often as I had during late spring thru the summer. To be honest I had become a little bored with it but more importantly, since I've now incorporated deadlifts and the (dumbbell) squats into my workout, I worry that bike riding won't allow my body enough time to recover. Sleep is something often talked about in here. I've never been a sound sleeper. There are nights when I do get seven or eight hours sleep but my average is about 4.5-6 hours (and I'm lucky if I can get six). But I still go to the gym. Like I posted in today's journal entry, I think that one big reason I hadn't been lifting as much is because of negative thinking which I'm determined to push through. I push myself because I know the body I must have. And for me I feel guilty if I don't get to the gym. I'm not at CNS burnout, thank goodness, but it's important to know the signs.
