Muscle-to-Fat Ratio
1.5:1 to 2:1 (muscle to fat). A higher surplus means more total muscle gained per week, but the fat-to-muscle ratio gets less favorable.
Training Recommendation
Train 4-6 days per week and push volume to the upper end of your recovery capacity. Target 15-20 hard sets per muscle group per week. At a 12% surplus, your body has plenty of fuel to recover from high training loads. Use this window to push personal records and add muscle as fast as possible.
When to Start and Stop
Ideal Starting Body Fat
10-15% body fat. Starting lean gives you more room to add muscle before you need to cut. Most men look and feel best bulking from 12-14%.
When to Cut
Cut when you reach 18-20% body fat or after 6 weeks. At a 12% surplus, fat accumulates quickly. Do not extend beyond 6 weeks without assessing whether the muscle-to-fat ratio justifies continuing.
Who Is This For
Suitable For
Advanced men who need maximum muscle growth in a short timeframe. Best for experienced lifters starting at 10-13% body fat who plan to cut afterward. Requires disciplined training to justify the higher surplus.
Not Recommended For
Anyone above 15% body fat. Beginners (who can gain muscle at maintenance or even in a deficit). Those who dislike gaining visible fat. Anyone not training at least 4 days per week with progressive overload.
Frequently Asked Questions
When should I stop bulking?
Cut when you reach 18-20% body fat or after 6 weeks. At a 12% surplus, fat accumulates quickly. Do not extend beyond 6 weeks without assessing whether the muscle-to-fat ratio justifies continuing.
Do I need to train differently during a bulk?
Train 4-6 days per week and push volume to the upper end of your recovery capacity. Target 15-20 hard sets per muscle group per week. At a 12% surplus, your body has plenty of fuel to recover from high training loads. Use this window to push personal records and add muscle as fast as possible.
Should I do cardio while bulking?
2-3 sessions of low-intensity cardio per week (20-30 minutes of walking, cycling, or swimming) is recommended during any bulk. Cardio supports heart health, nutrient partitioning, and appetite regulation without interfering with muscle growth.
What is the best starting body fat percentage for a bulk?
10-15% body fat. Starting lean gives you more room to add muscle before you need to cut. Most men look and feel best bulking from 12-14%.
