Train with your body, not against it.
Sports science was built on men. OnlyGirls flips that — Aura reads your cycle, hormones and wearables and tunes training, fuelling and recovery to the phase you're actually in. This is performance, female-first.
The Cycle-Synced Engine
Four phases. Four game plans.
Your hormones swing across the month — so your capacity does too. Aura maps where you are and loads the right intensity, fuel and recovery for each phase.
Menstrual
Gentle movement and mobility. Iron-rich fuel. Permission to go easy and rebuild.
Follicular
Rising energy. Progressive strength, skill work and higher intensity — chase adaptation.
Ovulatory
Maximum power. Go for PBs, sprints and heavy lifts — your strongest window of the month.
Luteal
Steady endurance and form. Prioritise recovery, magnesium and smart carbs as energy dips.
Inside the engine
Your personal Performance Index.
A daily readiness score
Sleep, HRV, energy and cycle phase fused into one number — so you know whether to push for a PB or back off and restore.
Phase-aware sessions
Strength, conditioning and mobility that shift with your cycle — built for output, never punishment.
Fuel that fits the phase
Protein, iron, magnesium and carb targets that move with your hormones, plus recovery cues from your wearables.
Our commitment
Female-first, for real.
We champion women in sport and invest in the science of the female body — so performance is finally built around how you're actually wired, not a male average.
Champion women's sport — we back the athletes the world overlooks.
Advance the science — built on the female body, not borrowed from men.
Train smarter — every insight flows straight back into your day.

I stopped fighting my cycle and started training with it. Two PBs in a month — the power-window sessions are unreal.

Questions, answered.
Do I need a wearable?
No. Aura works from your cycle and quick check-ins alone — but connecting Apple Health or Google Health Connect makes your readiness score sharper.
Is this only for athletes?
Not at all. Whether you're starting out or chasing PBs, training with your cycle helps you get more from every session and avoid burnout.
What if my cycle is irregular?
Aura adapts to your real data over time and still tailors guidance day to day, even when your cycle isn't textbook.
