I always find it interesting to see how different people (lifters, coaches, trainers, etc.) do workout splits. I tend to mix it up every month or so between full body workouts, anterior/posterior splits, or upper/lower splits. It also depends where I am in the season and if I'm lifting more than once a week. Right now I'm lifting 1-2 times a week so today I did a posterior chain workout and will do a front/back split for the next couple weeks before I drop down to one day of lifting a week. Then I'll go full body.
