Frequently Asked Questions

What's optimal body fat for athletes?

It varies: Male endurance 6-13%, strength/power 6-16%, female endurance 12-20%, strength/power 14-24%. Find what supports YOUR best performance.

Is lower body fat always better for performance?

No. Too low impairs performance, recovery, and health. Many athletes perform best slightly above 'ripped' levels. Find your optimal range through experimentation.

How do I get to competition body fat?

Plan 12-20 weeks of gradual fat loss. Maintain training intensity, increase protein, create moderate deficit. Don't crash diet - you'll lose muscle and performance.

Should I measure body fat in-season?

Yes, but don't obsess. Monthly checks ensure you're not under or over-fueling. Big changes during season usually hurt performance.

My sport has weight classes - how do I cut?

Maintain body fat slightly above competition level. Final cut should be water, not fat. Never cut more than 5% body weight in final week.
