Ok I know this topic has probably been beat like a dead horse, but im really confused....every topic I go into seems to contradict cardio and lifting purposes at the same time....I thought there was nothing wrong with lifting and cardio at the same time and even equalizing it. I dont want to really look like arnold schwarzenegger but in the same time I dont want to be a toothpick so my logical thinking is to do half cardio and half weights...about the only thing I really want to rotate is upper body from lower body....I would like opinions from everyone based upon their results, experiences from trainers, trainers themselves....please educated answers only though...Im confused enough as it is and dont need no help in that category
