Cycle-based training in the OvulaRing app for iPhone/iOS

“Cycle-based training is not only important for elite athletes, but also for women who train in their free time!”

Saba Shakalio, strength and conditioning coach for the FC St. Pauli women’s team, sports scientist and OvulaRing coach

Cycle-based training with the OvulaRing app and the Sport add-on (iOS)

Train in sync with your cycle. The OvulaRing Sport add-on shows you your cycle phase in real time, provides training & nutrition tips for each phase, warns you about overload/RED-S and helps you improve performance — with proven data protection.

With OvulaRing you can keep an eye on your cycle health anytime, anywhere and always know exactly where you are in your cycle. This lets you adapt your training optimally to your cycle phases. OvulaRing records your cycle and therefore also your training sessions in full. This makes it easy to check how much your core body temperature rose during training. You’ll also find out whether your training is putting excessive strain on you and whether your fertility may be affected.

The Sport add-on for your OvulaRing app

Take your training to a new level with the OvulaRing Sport add-on (currently iOS only). We support you in making your training gentler and more effective, in sync with your cycle.

What you get:

  • Real-time detection of your cycle phase
  • Cycle-phase-specific training guidance to improve performance, prevent injuries and maintain healthy hormonal balance
  • Tips for cycle-based running & strength training
  • Tips for cycle-based nutrition
  • Detect early symptoms of an energy deficit and overtraining to protect your fertility and performance
  • Monitor training load using your core body temperature
  • Track all your cycles and monitor your cycle health over time in relation to your training volume

How does it work?

OvulaRing Sport is an add-on for your OvulaRing app and integrates into your existing application. After purchasing the OvulaRing Sport add-on, you’ll be activated within a few business days and get access to all content on cycle-based training and nutrition in your app.

Using a toggle switch, you can easily switch between the fertility view and the sport view in the app. In the cycle-based training view, you receive training guidance based on the medically validated OvulaRing method for your individual cycle. It analyses whether you are before, during or after your injury-prone days in the cycle and gives you the appropriate information on what training fits best right now.

Under “Tips”, once the Sport add-on is activated, you’ll also find important guidance from our experts in cycle-based training. Currently you’ll find general recommendations for cycle-based training, as well as cycle-based running and strength training. More sports will follow (cycling, triathlon, yoga & Pilates). You’ll also find evidence-based recommendations for your sports nutrition depending on your cycle phase.

Sports science research with OvulaRing

In this study, sprint endurance performance was investigated for the first time in different phases of the menstrual cycle in the Bundesliga team of Hamburg’s female water polo players. Find out more here:

More studies

Professor Kirsten Legerlotz from the Humboldt University of Berlin used OvulaRing to examine cycle-phase-related fluctuations in performance in the German women’s rowing squad.

“In sports science research, OvulaRing can be used to investigate cycle-dependent fluctuations in performance in female athletes. In addition, OvulaRing can be used to identify anovulatory cycles, which occur relatively frequently in athletes and would go unnoticed without temperature tracking. Since cycle disturbances can also be triggered by overtraining or insufficient energy intake, training or nutrition can then be adjusted promptly.”

– Professor Kirsten Legerlotz

Professor Petra Platen from Ruhr University Bochum investigated cycle monitoring in elite female athletes using OvulaRing in collaboration with the DLV (German Athletics Association).

FAQ: Frequently asked questions about cycle-based training and the OvulaRing Sport add-on

Cycle-based training adapts content and intensity to your cycle phase (menstruation, follicular phase, ovulation, luteal phase). Goal: train more efficiently, avoid injuries, prevent overload/RED-S and protect fertility.

  • Menstruation (days 1–5): Light to moderate, mobility/technique, easy endurance. Breaks are ok if symptoms are severe.

  • Follicular phase (≈ day 6–12): Intensive & progressive: HIIT, sprints, max strength, plyos.

  • Periovulation (±3 days): Power/speed – with a good warm-up & landing technique (injury prevention).

  • Luteal phase: endurance base, tempo/threshold, hypertrophy, focus on recovery; deload in the last 3–5 days if you have PMS.

  • Live cycle phase guides weekly planning (power blocks in follicular/periovulation, endurance/hypertrophy in luteal).

  • Check your core body temperature after sessions: unusually high rise/persistently elevatedreduce volume/intensity the next day.

  • Frequent anovulatory cycles/short luteal phase → deload, review fueling, and involve a doctor/coach if needed.

Warning signs: longer cycles, no ovulation, short luteal phase, declining performance despite more training, fatigue, frequent infections. Response: 7–10 days deload, increase energy intake, manage sleep/stress; if signs persist, seek medical assessment.

  • Follicular/periovulation: Carbohydrates for intense sessions, protein for adaptations.

  • Luteal: Slightly higher energy & electrolyte needs (due to elevated core body temperature/fluid shifts); pay attention to hydration.

  • Menstruation: Well-tolerated, iron-rich foods; easy-to-digest carbs around training. (General information, not medical advice.)

Align exercise selection and intensity with your current cycle phase — this way you train effectively without unnecessary strain.

  • Follicular phase: Strength & power — train heavy (e.g., 3–5 sets × 3–6 reps), long rest (2–3 min), compound lifts (squat, deadlift, press).

  • Periovulation: Explosive strength — jumps, sprints, technique/speed in Olympic lifts; clean landings, good warm-up; keep load moderate.

  • Luteal phase: Hypertrophy & quality — moderate weight, 6–12 reps, RPE 6–8 (comfortably hard), controlled tempo, more prehab/core.

  • Menstruation: Technique/mobility/ROM — light training; a deload or rest is absolutely fine if symptoms are severe.

Quick note: RPE = “Rate of Perceived Exertion” (subjective effort scale from 1–10).

During this phase, connective tissue/neuromotor control may be affected. Measures: thorough warm-up, stability/knee control, landing drills, and moderating fatigue-related jumping.
