With such a topic so broad we truly try to cover the basics from all angles in this group. Nothing too big or too small. Nutrition is as significant if not more as exercise is to reaching your goals so learn all you can.
I searched the boards and could not find a specific answer on this.
My normal weight is around 180-190 lbs (5'11) but am at 220 currently. I will do HIIT 4 days a week.
QUESTION: Can I still do an arm/chest type of a workout on an off day or even before my HIIT or will that be over training and not get me the results I want?
I really don't want to lose a lot of mass in my arms...
It shouldn't be over training. Do the arms and chest training first, then HIIT. the HIIT 4 times a week might be overdoing it, though. I'd start out a little lighter, make sure you don't injure yourself.
Best of Luck!
-------------- If you have never failed,odds are you never tried.
If I can complete it no problem I don't know if that would be considered over training? I do 6 speed jog 9.5 speed "sprint" after 5 min warmup. I could go longer if I wanted at the same rate but I don't.
