Workout Guide, Calculator, and Progress Tracker
531 is a popular and proven barbell strength training methodology developed by Jim Wendler, an elite powerlifter and long-time strength coach. The routine focuses on building strength in the squat, bench press, deadlift, and overhead press. BBB stands for Boring But Big because you'll pretty much just be doing lots of work with a single lift each day. Though strength is the focus of the routine, it's also highly effective for goals like building muscle, getting toned, or losing fat assuming you follow your meal plan. Source
