Hi all. I just have a quick medical question. I’m not asking for a diagnosis, and I’m not ill or anything, so I think I’m still within the rules of this forum.
The situation is this: I’m a little bit tubby but otherwise in reasonably okay shape. I want to get leaner and more muscular and I’ve embarked on a program called ‘You Are Your Own Gym’, which emphasises exercise using your own body weight (push-ups etc…).
One of the key ideas behind the work out is this: If you keep your workouts short and high intensity, you will burn more fat than if you do cardio (like jogging) at a slow and steady rate. This is supported by numerous studies in the last few years and is uncontroversial among fitness enthusiasts.
However, the intensity of a workout is, as I understand it, technically measured primarily by heart rate. As far as I know, your heart rate has to get into the 150+ range (or thereabouts), otherwise it’s not high intensity. The higher your heart rate, the more intense your exercise.
Here’s where it gets complicated. I take beta blockers for panic attacks and even when exercising my heart rate doesn’t got up past about 130-140, and I have to push it for a while to get it that high. For instance, I’ve just done one of the workouts prescribed in the ‘You Are Your Own Gym’ manual and my pulse at the end of the workout was about 120, even though I was pushing myself pretty hard.
My question is, will this program work for me as advertised? If my beta-blockers don’t let my heart rate rise all that far, is it possible for me to have a “high intensity” workout? Is it the case that the beta blockers prevent me from having a high intensity workout? Or is a heart rate of 120 intense for me, in my specific instance?
Thanks in advance.
