Hello doctor,

I am a 400 lbs, 35-year-old male who did not do exercise but I just started going to the gym since past week. The first three days my maximum HR was 150 on the treadmill and I felt fine and I would do 40 minutes on it and today I only did 30 minutes because I started to feel a little dizzy and my HR went up to 158. Why is that?

Hello,

Welcome to icliniq.com.

I understand your concern. It is normal for the heart rate to go as high 300 bpm. You are exercising the wrong way for someone with your weight. You have to start exercising by taking a five-minute walk on the treadmill before gradually increasing the pace to a speed of 5/6 for 10 to 15 minutes. You should do this routine for two weeks before gradually increasing the duration to 20 minutes. Increase the speed gradually as you get used to. You get the dizzy feeling because your heart is having to pump more blood as you run, which it is not used to. You will over come this feeling as times goes on.
