Agree.
Kuan, the 220 formula is a statistical average for large cross sections of a population. Individual max heart rates can vary by as much as 15 beats per minute above or below the 220 - AGE results. Some people may even vary by as much as 20 BPM.
The 220 - AGE would have my MHR at a paltry 175 BPM. However, I've had it tested at 191 BPM.
Suggest you have a stress test done.
