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 12-16 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
18-24% body fat. Starting in the fitness or upper-athlete range gives you room to add muscle without exceeding comfortable body fat levels. Most women prefer bulking from 20-22%.
When to Cut
Cut when you reach 28-30% 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 women who need maximum muscle growth in a short timeframe. Best for experienced lifters starting at 18-22% body fat who plan to cut afterward. Requires disciplined training to justify the higher surplus.
Not Recommended For
Anyone above 25% 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.
