February 6, 201412 yr Normally on my cardio workouts I try to burn at least 500 calories, which normally takes me 20-30 min depending on intensity. Pretty much every time I end up around 180 bpm, I don't feel dizzy or have a shortness of breath or anything. 180 bpm is pretty much 100% of my max HR based on the widely accepted formula 220-age (220-35 in my case). Many cardio machines have stickers nowadays showing fat burn zone, cardio, some also show the red zone, or danger, so this is where I and up. Is it really dangerous to push yourself there? I should mention that I've been in very active and participated in some kind of sport activity at different time periods of my life so always considered myself fit, still all these stickers make me feel uneasy, I don't want to drop dead on a tradmill or whatever if that is a possibility at all?
February 6, 201412 yr always in the past people compete in running, bicycle, swimming etc etc, try to be the first one and did not had any heart monitor. Giving all the can and not die. So I would say there isn't much risk if you are already trained. If you aren't trained, fat or with heart problems it looks total different. That 220 minus age is approx. There are people who can go higher and there are people who can not. I guess safest estimation is: If you feel happy and well it is OK. If you feel bad it isn't OK. (considering healthy, no heart problems, no drugs, enough to drink, normal temperature....just trust more in common sense than in the digital toy).

It kind of makes sense what you're saying, but I've read of stories of people dying under high strain, like marathon runners... When I train at the lower intensity (like last night I burnt 530 calories during 40 minutes cardio, which included 5 min warm up and 5 min cool down), my breathing didn't change much and I barely broke a sweat. HR stayed around 140 but I didn't feel like I was working hard.

But usually on these city marathons at least half of them try to run as fast as they can, and no one dies. (but keep in mind...don't exercise for 20 years, be heavy overweight and than max out the heart may still be extreme unhealthy). And I would do more warm up till I go to the maximum.....If you don't have time rather keep the cool down short, but not the warm up.
February 8, 201412 yr Do you use these integrated HR thingys? Complete useless; get yourself a decent HR meter, from Pulsar for example.

February 9, 201412 yr The key thing is to make sure you don't have any underlying cardiac disease. Have a general physical check-ip with stress test if you haven't already.
