Some history: I've always been guility of doing too much cardio. Even when following a rotation, I always addes extra cardio for fear that I would gain weight. I had begun to feel worn out and knew if I didn't make a change (I've been doing this for over 10 years) I was going to either get an injury or ruin my enthusiasm for exercise. I did 2 months of the January rotation followed by two months of the July rotation, following them exactly. The results have been incredible and restored my enthusiasm. I have been doing less cardio than before and including more rest days. Visually, my body responded well-weight loss and increased definition; my legs didn't bulk like they always tended too either. BUT I have noticed a big change in my heart rate. I used to struggle to keep it above 136, but now find the same workouts raise it into the 150's and 160's. Doesn't this mean I am actually less cardio-vascularly fit? I should also add, that due to a very upsetting seperation and pending divorce, I have been "heart-sick" in the stomache and not eating as well as I usually do, and have been under a lot of stress. Can these factors be part of the equation as well? And should I be concerned or just satisfied with the visual improvements? Also, and I will probably make a seperate post, but does anybody have any suggestions for a support group online for divorce? Thanks in advance for your help.
