Frequently Asked Questions
Do I need to take diet breaks during this cut?
For a short cut like this, diet breaks are optional. You should be able to complete the phase in one block without metabolic issues.
Can I build muscle while going from 15% to 12%?
Unlikely. At this body fat range, your primary goal is preserving the muscle you have while losing fat. Focus on maintaining training intensity and eating enough protein (1g per lb lean mass).
What is the best workout plan for this transition?
Maintain a resistance training program 3-5 days per week with compound movements (squat, bench, deadlift, overhead press). Keep volume at 80-90% of your normal levels. Add 2-3 sessions of 20-30 minutes of low-intensity cardio (walking) per week. Do not add high-intensity cardio on top of a calorie deficit.
