Okay, Daisy, this one's for you. I'm on my regualar e/c stack, doing my normal routine, 35-45 min lift, then 30 min cardio. During my lift, I'm all sweaty, heart rate is high, everythings hunky dory, then i start my cardio, medium intensity, eliptical, then about 10 minutes into it, i get REALLY COLD, my heart rate slows, i don't think dangerously slow, but slow like i'm sitting at my desk typing on the comp. I stopped my cardio, cause it kind of scared me, has anyone had a similar experience??? It was really wierd.
