That style 3 day a week split can also work well when breaking up the upper body in separated groups. You may want to break it up a bit differently , but the general rule of thumbs follows:
Monday....chest, delts & triceps
Wed.......legs, hams & calves
Friday.....Back/lats/ traps & biceps.
Will only be working a given body area once a week. But if each workout day is planned, with forethought, one week can be ideal for lots of folks. If that work for you, than great. If not, than go onto something else more suitable for your body type and needs.
The above type program can also be good for older gentleman, who still wish to train with serious intent. Allowing more rest between body parts and training days.. Common mistake is not adjusting the work load, as the body ages, to a lower level. Can still train heavy, but training smart may prove to be most important. Recovery and the CNS (the key to progress) will need more time to adapt and actually heal between workout sessions. Good Luck.
