I've been doing a lot of research on the best way to work out. And almost everywhere I've looked says that two-a-days are the best way to do it, because you can hit everything twice per week and get 2 post workout meals a day. I have never done two-a-days before, I have only worked out for 2 hours hitting 2 different body parts and made some pretty good gains. What does everybody else think about this?
