I hear cardio on an Emory stomach is good, but weight lifting is not. I want to do cardio before workout, and was recently on here asking about hiit regimens, but am worried about crossing the line into catabolism by working too intensely. I want to do intervals on rowing and elliptical which should be fine, but also a ladder routine of burpees-jump rope-box jumps; and tire flips into rope (idk what it's called but ropes are wrapped around like a pole and you swing your arms like donkey kong)...if tire isn't too heavy and burpees don't involve push ups should i be ok?? Thanks
