if you have more than 2 days a week to spare for gym - go for a split routin

if you only have 2 days or leess a week - go for full body.

and you can find one by going to the gym and working out I usually get some ideas for workouts from google and then just add them to my day pla. I am going for a split workout. therefore - figure out what combos you want to make, e.g. biceps +back+ chect etc, then find the workouts for these groups and make sure you watch some videos of how to erform them correctly, then hit the gym.
