Already my HR is around 165-175 when doing HIIT on the recumbant bike, and today after taking some no-explode and then doing HIIT my HR was hovering around 175 even going as high as 188 during the most intense intervals. I feel fine when doing this, I mean it's hard but I survive; but it's much higher than the recommended cardio HR of like 160 that is written on the machine for my age. I'm not going to plop over dead am I?

I do 20 minutes of HIIT and I hit 190 at peak, mostly around 185
treadmill, incline 4, speed 9

okay, well now i'm not too worried. i figured HIIT would probably get your heart rate higher than just regular cardio would, i just wasn't sure by how much. good to know.

I dont see how anyone does more than 10 mins of HIIT (non modified times), but ive always been a bitch about cardio.

I love me some cardio, but hate long distance runs.

20-30 mins of HIIT is a great feeling for me. in that 30 mins I will peak about 8-10 times, 12 if pushing it. but it feels good man.

10 minutes is nothing, although 20 minutes is pretty hard for me. I originally did 16 minutes because I first got the HIIT from the Max-OT workout which had what they called Max-OT cardio which was just 16 minutes of HIIT. So I shoot for 20 minutes of crazy intensity knowing that I'll be happy even if I bitch out around 16 minutes which I do sometimes.

220 - your age = age-adjusted Max HR

24yo=196bpm

It's an estimated result, since you can't be exact without being tested by a cardiologist.

For conditioning, and you haven't just started a regimen, shooting for 80-90% is reasonable.
