The Build-Your-Own Bodybuilding Adventure is a 6 (to 12) week classic bro-split. This 4-day muscle group split follows a proven structure that’s delivered results for decades. But unlike cookie-cutter programs, this version is fully customizable. Each workout gives you plug-and-play choices for compound lifts, accessories, and pump finishers, so you can tailor every session to your preferences, goals, and available equipment. It’s the perfect blend of structure and flexibility—just enough guidance to keep you progressing, with the freedom to train how you like.
 
This program is best run in a commercial gym setting, where machines and cables offer maximum variety, but nearly every exercise can be swapped for a dumbbell, barbell, or bodyweight alternative—making it garage-gym friendly, too. Expect a satisfying pump, consistent muscle growth, and a renewed sense of ownership in your training. Whether you're after aesthetic improvements or just want to have more fun in the gym, this is a split that works—every time.
 
Digital download includes a detailed program breakdown (pdf), detailed exercise selection list (pdf) to customize your weekly workouts, and a 6-week working template (xcel) to make notes and track progress. This program is effective as it is at 6-weeks, but can be repeated for 12-weeks of gains.
