start off slow and ez then work your way into a 3 day split, with rep ranges from 8-12
a sample 3 day split is:
monday: chest/triceps
weds: back/biceps
fridays: legs/shoulders

2-4 different exercises per muscle group with warmups sets then 3 sets of 8-12, adding weight after each set. Focus more on the chest and back as they incorporate the triceps and biceps respectively.

abs can be thrown in whenever, altho if you do deadlifts and squats, i wouldn't worry about them
