There are too many different ways to split up your training to list here. There are some ways that work a little better or a little worse for certain people. Some splits work better for certain goals others do not.
Off the top of my head I can think of about 15 different splits that I’ve used myself while training and I’ve gotten good results off most of them. For the first time I’m actually interested in getting larger and stronger (though I’m cutting right now) and my split looks like this:
Sunday: Quads and Chest
Monday: Delts and Calves (back/hams recovery)
Wednesday: Glutes/hams and back
Thursday: Arms (delt recovery work)
That doesn’t include cardio and some of the other stuff I do. This is just what’s going on at the moment and I quite like it. Though I’ve decided I need to get some delts and some arms (in that order) so once I’m done cutting I’ll go on a delt specialization followed by an arm specialization.
With my clients I use all sorts of splits depending on their goals, experience level, schedule etc etc etc.
If I were you I’d start doing a lot of reading on the site.
