For too long, the menstrual cycle has been treated as a fitness hurdle. But science is flipping that script, and showing that your cycle is actually a powerful performance guide.
It’s not about training less - it’s about training smarter.
“Women are not small men. Our physiology is different, and that should be reflected in how we train.” - Dr. Stacy Sims, exercise physiologist and author of ROAR
KNOW YOUR CYCLE, OWN YOUR TRAINING
Let’s break down the key phases of the menstrual cycle and discuss how to work with them, not against them:
1. MENSTRUAL PHASE (Days 1–5): Reset and Recover
Hormones: Estrogen and progesterone at their lowest
How you might feel: Fatigued, crampy, low motivation
Best training: Gentle movement like walking, mobility, yoga
But: If you feel strong, go for it. Some athletes hit PBs here
“There’s no rule that says you can’t train hard on your period. It’s all about individual response.” - Dr. Georgie Bruinvels, sports scientist
2. FOLLICULAR PHASE (Days 6–14): Go Time
Hormones: Estrogen rising, progesterone still low
How you might feel: Energised, focused, motivated
Best training: Strength, high-intensity intervals, new skills
This is a prime time for performance gains and building muscle
“This is your power window - recovery is better, energy is higher. Use it.” - Dr. Stacy Sims
3. OVULATION (Around Day 14): Peak Potential
Hormones: Estrogen peaks
How you might feel: Strong, fast, coordinated
Best training: Heavy lifts, sprint work, competition
Caution: Slightly higher injury risk, so warm up well and stabilise joints
4. LUTEAL PHASE (Days 15–28): Tune In, Not Out
Hormones: Progesterone rises, estrogen dips
How you might feel: Bloating, mood swings, energy dips
Best training: Moderate cardio, lighter weights, technique
Focus on recovery — hydration, sleep, and stress reduction matter more now
“This is when smart athletes adjust their training, not abandon it.” - Dr. Nicky Keay, endocrinologist
SMART TOOLS FOR SMARTER TRAINING
Track your cycle: use apps that help align workouts with your hormones
Eat to support your phase: More protein in the luteal phase, carbs when energy dips
Talk to your coach or personal trainer - cycle-based training is becoming the new standard in elite sport
THE BOTTOM LINE
Your cycle isn’t a setback - it’s a blueprint for peak performance.
By syncing your workouts to your hormones, you’ll feel better, recover faster, and train at your best - from PMS to PBs.
