MENSTRUAL CYCLE.

You can train throughout your menstrual cycle, but some days might feel harder than others. Adjust your sessions based on how you feel rather than following a fixed plan for each phase.

Train around your symptoms, not a fixed cycle calendar. Keep a shorter or lighter session ready for difficult days. Track symptoms and recovery only if it helps. Get heavy bleeding, severe pain or missed periods assessed. Discuss contraception or iron needs with your clinician

Use symptoms, not a fixed calendar

Average performance differences between cycle phases are small and the evidence is limited. Your symptoms still matter; an app's prediction shouldn't overrule how you feel. (1)

Put it into practice: Keep a routine across the month and adjust around actual symptoms and recovery, rather than automatically cancelling a phase. (4)

Train throughout the month

Research hasn't established an advantage from concentrating lifting into one phase. A small recent trial found similar strength and muscle gains across approaches; short-term muscle-protein responses don't prove long-term growth. (4) (6) (5)

Put it into practice: Put your harder sessions where they fit your week and how you're responding, rather than treating a predicted phase as a requirement.

Adapt difficult days

Exercise may help primary period pain, but severe or recurring pain deserves assessment. Pushing through it isn't necessary for progress. (7)

Put it into practice: Have a smaller option ready: fewer sets of your main exercises, a comfortable walk or rest when needed.

Contraception is an individual decision

Oral-pill studies show small average performance differences and no clear disadvantage for strength or muscle gains. Findings don't cover every formulation or contraceptive method. (2) (3)

Put it into practice: Choose contraception with your clinician around health and circumstances. Your coach can help adjust training; don't change treatment based on an average exercise result. (2) (8)

Check heavy bleeding and fatigue

Heavy bleeding can lead to iron deficiency or anaemia. Iron is useful when there's an identified need, but fatigue can have several causes. Australian heavy menstrual bleeding guidance (8)

Put it into practice: Get severe pain or heavy bleeding assessed, noting its effects on work, sleep and exercise. Ask before starting iron. (7)

Investigate missed periods

Not getting enough energy for your training is one possible cause of missed periods, especially with fatigue, stress injuries or declining performance. Pregnancy, contraception and other conditions can also affect the cycle. (9)

Put it into practice: Get unexplained changes assessed. Tell your clinician or sports dietitian if you've increased training or reduced food intake. (9)

Track only what helps

A few cycles of notes may help you recognise useful patterns, but tracking and sharing detailed information are optional.

Put it into practice: If it helps, briefly record symptoms, bleeding, sleep and training, then check whether your adjustments made sessions more manageable.
