You need to read a physiology textbook.

Try 30 incline and then come back.

Yeah right, nobody does 30 minutes on that thing.

I'd love to try one of these.

I think a climbing version would be great too.

I do 30 minutes on it

I'll do 30 minutes on your thing

You preparing to run up a mountain or something?

Nobody can do more than a minute and a half on it.

I've done 45mins with the first 30min using a 30# plate carrier.

I usually do 1000 steps at end of workout at like 70-80 steps/min. I like doing stairs now.

looks dangerous af

How fucking so? Do you fall off of treadmills too?

Try 15 minutes rowing you fag.

Doesn't work like that, please educate yourself on how to train correctly.
