It works best if you train four times a week, although three times a week could work as well, as long as you train all four core lifts before repeating. In other words, don't skip one so you can do the other three once each week. Don't train more than two days in a row. If you want to see the results of 5/3/1, you have to do the program as written. As soon as you start customizing it, it's no longer 5/3/1. You might like your own version of it better than the original, but you can't attribute your success or failure to the guy who wrote the program unless you're actually doing the program as he wrote it. Sample Workout: The Triumvirate The Triumvirate uses three exercises per workout, one of which is a core lift. Before each workout, do a warm-up that includes mobility, flexibility, something to raise your core temperature and heart rate (like rope jumping), and foam rolling. I recommend adding two or three conditioning sessions per week, using hill sprints, Prowler pushes, or whatever else works for you. In all workouts, rest 3 to 5 minutes between sets of the core lift, and 1 to 2 minutes between sets of the assistance exercises. Remember that you're calculating percentages based on 90% of your current 1RM in each lift, not from the actual 1RM.
