Kills the knees in my experience.
My body is about as responsive as a cold gelatinous ooze. HIIT also is bad for people with injuries.

What was your work:rest ratio?
Running, cycling, etc would all have the similar influence on things like lactate threshold and blood pH but would have different stresses on your joints
I was doing 30 minutes of HIIT 2 days a week with 3 days of strength and 2 rest days.
I’ve had occasional knee aches for a long time prior to that though.
I found the best workout for me was hopping on an elliptical for 30-40 minutes a work out.
I am not the authority, I am just another person with some letters after their name. So what I think is just some shit some rando thinks…
Personally, I think that’s too much. Not just the length of your HIIT workouts, (15:15 I assume?) but adding 3 days of lifting? Unless you’re 22 with a nutritionist, that’s a LOT. I admire the grind for sure. But that’s a loooooot of work brother.
Recovery is incredibly underrated. Sleep is incredibly underrated. I am of the opinion most people can get far more results with far less work. But there’s massive biological variation and I can’t sit here and tell you anything without really knowin ya
It was just light strength stuff curls and what not.
