Hey everyone, quick question, recently I’ve started to work out at home as it’s getting colder or if I don’t have time to get out. Ive been following along with HASfit on YouTube, doing the low impact cardio workouts, that are full body and HIIT, recently someone told me that HIIT is to build muscle? I had absolutely no clue that was the case. I’ve only done the workouts maybe 8-9 times. So would this potentially put me into blue territory? I haven’t been using any weights while doing the excersizes.
Any input would be greatly appreciated!
