Hey guys, I finally started doing HIIT, my first time was on wednesday, I did four cycles of 8s sprint and 12s rest before my legs died (pathetic I know, yay for fast twitch muscles), today I did five of them.
My question is, should I just keep trying to do more cycles everytime I do HIIT?
Or should I go and get some endurance into my legs first?

Shameless bump.
Off to shower, hope to see some answers when I'm back.

You really shouldn't be doing HIIT until you can do 45 minutes of continuous exercise at around 85% of your max heart rate. I'm still working my way up to 25 minutes of running.

Usually it's for athletes who need to improve after they've reached a plateau.

I mean, yeah, try and work up to a few more cycles, but not to many more, you should be working at a sprint like pace for the whole exercise.

But the problem isn't my "breathing", it's my legs.
In the last cycle my body just falls forward while my legs lag behind because I can't move them fast enough anymore.

Off to shower for srs now.

Yeah I'm sprinting, at the end I can only jog though.

You know what? Scrap what I just wrote before, I did some research and it seems that running as if there's a mad man with a chainsaw coming after you is better cardiovascularly and for fatloss.

Gonna keep researching for a while but this is the first piece of info I found.

Is it just me or does this sound like some sort of superhuman feat? Or am I making this out to be harder than it actually is?

It must have been a typo, probably ment 65%

85% is almost a sprint, for 45 minutes? Not happening

Haha this thread is still here even after my night shift.
/fit/ is slow nowadays eh?

85% is only 175-178HR

it would be easy to keep that up for 45m-60m

intervals should be done at least 90% and preferably 95%+
