What's everyone's opinions on doing double splits. Right now i'm doing a push/pull/legs routine and i'm splitting the push and pull days. I know twin peak is a big advocate so please chime in. I would also like to hear what bobo along w/everyone else has to say on the topic.
For me recently i've been so busy that i've had to split up my workouts b/c i only have around 30-45 mins of time to workout each day. I'm a personal trainer so i'm always at the gym but i'm also a student so i'm very busy right now (damn summer school). These started out of necessity but i've found i like them MUCH more.
My concerns are that my cortisol levels are going to get our of control training twice a day. It's also harder to control my calorie intake as i like to take in a good amount of carbs around my workouts. Really just looking for what everyone thinks of training twice a day and also any science backing one way or the other would be awesome. Thanks.
EDIT* How long of a break does everyone think is necessary in between each workout.
