This 12-week program is a high-stimulus, 4-day Upper/Lower split designed for maximum hypertrophy, with the core strategy mandating pushing every working set to very close to or all the way to failure (0 RIR). The plan follows a block periodization model: Weeks 1-4 build work capacity and focus on technique; Weeks 5-11 escalate intensity to near-maximal failure, with a slight volume increase in the final three weeks for a maximum stimulus overreach; and Week 12 is a crucial deload, cutting volume and intensity by half to dissipate fatigue and solidify gains. For nutrition, if the goal is muscle gain, a caloric surplus of 250-500 calories is recommended, while a fat loss goal (500-750 calorie deficit) requires mandatory training adjustments, reducing all non-compound sets by one and limiting compound lifts to 1 RIR to prevent burnout. Workouts average 60-90 minutes. Prioritize quality of effort over marathon sessions.

This program is built around a full gym. Make sure you have consistent access before starting, since the progression model assumes you can perform the same movements week over week.

Each session typically takes around 80 minutes to complete. That estimate covers your working sets but doesn't account for warm-up or rest between sets, so budget a little extra time when you're first learning the movements.

Lyle & Soloman Inspired Upper Lower Split is structured around 7 training days per week, with rest days built in to allow for recovery. The Boostcamp app lets you reschedule sessions if your week doesn't go to plan.

The program runs for 12 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.
