For years I've been doing a basic push/pull routine.
This is to state I do chest, shoulders, and triceps on one day, then back, biceps and legs on the next day taking day 5 off and then back to it.
It works ok but I'm just getting bored.
Having two kids, coaching baseball, and running a business keeps me busy so I can't spend more then 90 min at a time in the gym, and as it is I need to do more for Cardio
