Right now I am doing a split routine M and Th Chest, Tri's and Shoulders and T and F - Legs, back and Bi's. Sticking to all compound exercises and doing well so far.
I am also doing HIIT on M - W -F - 5 min warm up then 60 seconds at 80 to 90% max heart rate and then back down to 70% for 10 cycles -. Other days I walk on the treadmill around 60 to 70% of Max HR.
Will doing HIIT impact my gains on my legs - is this too much stress for my body to take?
