Regular cardio. Mixing up with different types would be beneficial as well.

It's just like any other muscle bro. Just be sure to get that time under tension. Don't skip eccentric contraction, the more you slow down your heartbeat, the more gainz you get. Isometrics are good too, and are a great finisher to your workout

going by science:
HIIT

also don't do coke

I know this is a dumb question but I wanna confirm my suspicion. I just started cardio and my heartrate is becoming accustomed to it quick. The first day I was hitting 180bpm and now I do the same intensity and only hit 140. To increase it should I up resistance or intensity or both? I feel like I'm wasting time if I'm not on the brink of death.

Don't be afraid to show your vulnerable side. Love and be loved.

You don't need to. Just squat heavy, strong quads can replace a weak heart.

subtract your age and your resting heart rate from 220 and aim for that #+ 75% of that #

So I should go for 271 bpm? nice formula retard

That's literally THE cardio formula fag
(220-age)*.75 = target heart rate
I'm 20 so my target heart rate is 150 bpm. For a good workout maintain atleast 30 minutes of excersize at that heart rate.

HIIT is anaerobic

Both those heart rythms are deadly find a better pic. First is a fib. Second is v tach with a wide qrs.

You (I'm assuming) wrote it wrong the first time. You said +75% which is different.
