If you're looking to build muscle and gain weight, all that cardio will set you back unless you are doing an HIIT style workout (limits to ~15 minutes).
If you're going to do a 5-day split, I would do the following:
Monday: Legs
Tuesday: Bi's, Tri's, Forearms, Abs
Wednesday: Shoulders, Traps
Thursday: Back (Lats, Good Mornings, Hyper Extensions)
Friday: Chest
After a few weeks, mix it up and do:
Monday: Legs
Tuesday: Chest and Abs
Wednesday: Back and Traps
Thursday: Shoulders and Triceps
Friday: Biceps and Abs
