Hi, I hurt my foot and it will take several months to heal. I've been looking on Darebee for some HIIT routines I can do while sitting down. I found a few, but they are limited to upper body or wheelchairs. I can actually move my legs while sitting in a chair -I just can't walk very well. Almost all the seated charts (for office, etc) are not HIIT. I wonder if I could just convert regular routines into a HIIT routine? Any suggestions on the best way to do this? Or how to examine whether an exercise really shouldn't be converted to HIIT. Thanks!
