Hi Cathe--I know you're busy w/STS orders & don't know if you'll see this, but I was hoping you could clear up my confusion. Last night a trainer told me that, based on my age, height & weight, my HR should stay in the 140s for me to lose weight. Cathe, my HR is in the 140s during your WARMUPS!!!!! I usually average 160-170 w/most of my cardio. Sometimes, esp. w/intervals, my HR rises to 190. According to the program in my HRM, my zone is 140-170. So, is my HRM wrong, is the trainer wrong, or is there something wrong w/me? I'd really appreciate your thoughts! Will post in OD too so I can get others' input.
