Heart and exercise

> cell death due to lose of oxygen
Your o2 absorption doesnt drop like that. Otherwise you wpuld show symptoms of blood asperation (sepsis). And even then once you stop the exercise you blood will go back to being flooded with fresh o2 after just a few minutes.

exercise increases pumping efficiency of the heart. It literally increases the strength of which the heart contracts. this is why athletes oftentimes have larger hearts

Well thats good to know. I work out for about 1 hour 3 times a week. My heart rate is usually between 140 to 180 during that time. I understand how skeletal muscles benefit from exercise but skeletal muscles get breaks. The cardiac muscle does not. Its always working. I guess this is why revving it up during a work out doesnt make sense to me.

A healthier heart is a stronger heart.
The stronger a heart is the more blood it pumps per beat.
The more blood it pumps the less frequently it needs to pump, lowering your heart rate.

You may benefit from rigorously monitoring your heart during exercise. Once you find a good range and stay within it, the fear basically goes away completely since you've gained control over it.

I dunno about that, I tried that and it's not nice when your heart rate is 170-180 (I do HIIT) and you check it, see the numbers that high and start getting anxiety.

The way I cope with it is by knowing my heart wouldn't be capable of getting that high if it wasn't healthy in the first place, and I try and inject some logic by thinking that even though someone people who apparently seem healthy just drop dead, driving to the gym is inherently far more dangerous to me than doing exercise.

Just try to live in the moment and focus on your breathing and maybe some of what I mentioned above. FWIW when I started at the ym 2 years ago my rest heart rate was between 90-100 and now it's 45-55 depending on the time of day. The highest I've gotten it is 182 and I swore to never check again after that. If I'm gonna die, odds are it's going to be something else at a young age.
