I do a half hour of HIIT cardio, 6 days a week, and have been for about 3 months now. I was expecting soreness in the beginning, but I'm still experiencing it, and was wondering if I'm not giving myself enough rest. From my understanding, when muscles are sore, a couple days of rest before working them again is important. Generally cardio doesn't get people sore, but since I'm doing HIIT, I'm targeting my thighs, butt, etc.intensely 6 days a week. My main goal is fat loss but muscle preservation is very important too. My muscles aren't so sore that I wouldn't be able to make it through these HIIT sessions, but I just don't want to be breaking down muscle. I really don't want to skip out on cardio more than 1 day a week, and I've found that interval training instead of steady cardio is really the only thing I see results through,, but I feel like I could be stripping my muscles with 6 days of HIIT since I'm experiencing sore muscles. Thoughts please?
