Female-Corrected Composition Markers
Headline body-composition + cardio markers with female-specific corrections applied.
Notes & caveats
- · FFMI ceiling for natural female lifters: ~22 (Kouri 1995, n=157).
- · Mifflin-St Jeor uses the −161 female sex constant verbatim.
- · Max HR uses Gulati 2010 women-specific formula (206 − 0.88×age) for better accuracy than Tanaka.
How to use it
- Open Female Athlete Formula Suite and enter your current baseline accurately.
- Adjust one variable at a time so changes are easy to interpret.
- Review the headline output first, then inspect supporting metrics.
- Run at least one conservative and one aggressive scenario.
- Use outputs to set your next training or nutrition action for the week.
- Save or share this setup if you want to revisit it later, then check one easier and one harder version before you change your plan.
