Alex azarian (RIP) would not let me do anything but stairs…BUT my legs are one of my strongest body parts….idk if that factored into it, or he was just a sick mean individual.
You can adapt to anything, I run 4-5 miles or bike 20-30 miles the day before legs sometimes and be ok, but it took 2-3 weeks before performance didn’t suffer.
Do both! 20 minutes stairs, finish the last 15-20 walking.
Also, if your a fucjing tank like
@danieltx or
@TheOtherOne55, stairs is probably fucking dumb and more like HIT.
