Well the best workout split you can do is one you can stick to consistently, here are some examples:
If you can only train three times a week with a day gap you can do full body three times or you can do a push (exercises that only target a pushing motion), pull (exercises that only target a pulling towards you motion) and leg split.
For four days a week you can do lower body, upper body, lower body and then upper body again or full body X 3 and one day of cardio or push, pull and legs then a break then full body
For five days a week you can do upper, lower, upper, lower and then full body
For six days a week you can do push, pull, legs, push, pull and legs again.
There’s are all examples you can use to follow or you can create your own split that works best for you. Just remember that they are all different depending on the your fitness goals that you want to achieve
