My split is like this... monday - chest/shoulders, tuesday back/abs, thursday legs/calves, friday -arms/abs. Every once and a while i have to switch up the days, like this week again I have to do legs on wednesday and take thursday off and then lift on friday for arm/abs. Does this really have a big effect, lifting 3 days in a row. The 3rd day is legs, a body part that one gets hit on this day. If it was the arm day on wednesday with no rest I would assume this would be a bigger problem. Comments?
