Had to have one after the bypass- but I cannot run due to the greek philospifor--"Dodgienees"

So walk on the tread mill but at 4 to 6mph. Technician went for a cup of tea after 10 minutes and came back and stopped me- I was up to 140 and he thought I was too high. I pointed out to him that on the bike I was seeing high 150's so he called in the cardiologist and did the Stress test again. When I got to 160 he asked if I was OK and said carry on- Got to 165 and I thought that was it but he was looking at the dials and said carry on- but he stopped me at 172. He told me to stop before I fell off the machine.

Now on the bike at that time I was treating 165 as my max but one hill we have and I did reach 172. That was get off the bike and lie down time- before I fell down.

Now that 220 less your age nonsense--At that time I was 53. Work it out- that formula worked almost spot on for me. OK not exact but near enough to say that 12 years later and I don't have to kill myself up every hill just to see if I can do it. Still see 165 occasionally- but prefer to see 155 as my max. It's easier.
