Would like to hear from some of the older, experienced HST'ers (I'm 46) on managing fatigue. I'm new to HST,on my 3rd cycle of straight HST (full-body 3 X weekly) after laying off training for several years. I need to lose a good deal of bodyfat (290 lb, 36% BF) which means I need to do cardio along with the weights. I usually do cardio (treadmill walking 30-45 mins) in the a.m. and weights in the p.m. I'm finding that this causes fatigue problems. I hate to give up the cardio but I was wondering if I should go to an upperbody/lowerbody split 6 days a week and drop the cardio? Any suggestions would be appreciated.
