Expert Tips for Bodybuilders

  • Off-season: stay 12-15% to bulk effectively without excessive fat gain
  • Start prep at 12-15% with 16-20 weeks out for safe, muscle-preserving cut
  • Stage-ready is 4-7% for men, 10-14% for women - unsustainable long-term
  • Use multiple methods: calipers, Navy method, and progress photos together
  • Don't chase numbers - how you look on stage matters most
  • Plan reverse diet after show to prevent rapid fat regain

Frequently Asked Questions

What body fat do bodybuilders compete at?

Men's bodybuilding: 3-6%. Men's physique: 6-8%. Women's bikini: 12-15%. Women's figure: 10-12%. These are temporary competition conditions.

How long does it take to go from 15% to stage ready?

Plan 16-24 weeks. Lose 0.5-1% body fat per month to preserve muscle. Rushing causes muscle loss and flat appearance on stage.

How do I know when I'm ready for a show?

You should be close to stage-ready 2-3 weeks out. If you're above 8% (men) with 2 weeks left, you're not ready. Better to postpone than compete soft.

What's the best body fat method for bodybuilding?

DEXA is most accurate but expensive. For regular tracking, use calipers or Navy method consistently. Progress photos with good lighting are essential.

How do I maintain muscle during extreme cuts?

High protein (1.2-1.5g/lb), maintain training intensity, adequate sleep, moderate deficit, and potential diet breaks every 6-8 weeks.
