HYROX for women over 40: training through perimenopause

16% of the women on Find HYROX Partner are 40–49, and they're among the most consistent athletes on the platform. This decade brings perimenopause, which typically starts in the mid-40s, and with it real changes to how you train and recover.

What changes

Falling and fluctuating oestrogen speeds up the loss of muscle and bone, can shift body composition, and often disrupts sleep (night sweats and waking). Recovery from hard sessions can feel slower. None of this means stopping. It changes what kind of training gives the most return.

1. Lift heavier than you think you should

For a long time women over 40 were told to use light weights. The evidence now points the other way. In the LIFTMOR randomised trial, postmenopausal women with low bone mass did supervised heavy lifting (around 85% of max) plus impact work twice a week for 8 months. Their bone density and physical function improved compared with a low-intensity group, with no increase in injuries (Watson et al., 2018). HYROX's sleds and carries are a natural fit; add 2 sessions a week of heavier compound lifts (squat, deadlift, press) in the 5–8 rep range, built up gradually with good coaching.

2. Keep impact in

Bone responds to impact. Running, jumping, and the burpee broad jumps in the race all help, as long as your joints and pelvic floor are happy (see our pelvic floor guide).

3. Eat more protein, and enough overall

Older muscle needs a stronger protein signal to grow. Around 1.2–1.6 g/kg/day, with 25–40 g at each main meal, is a well-supported target for active women in this age group (Morton et al., 2018). Don't combine perimenopause, hard training and aggressive dieting. Underfueling hits bone hardest (fueling guide).

4. Fewer, better hard sessions

Keep one or two genuinely hard sessions a week (intervals or race-pace stations), keep easy days easy, and plan an extra recovery day when sleep has been poor. Consistency over months beats heroic weeks.

Hormone therapy and symptom management are decisions for you and your doctor. The training principles above help either way.

General education, not medical advice. If something hurts, leaks, or stops (like your period), see a qualified clinician.

Frequently asked questions

Is HYROX safe for women over 40?

For most healthy women, yes. It's a good fit, combining aerobic work with the strength and impact training that protect muscle and bone during perimenopause. Get medical clearance if you have heart, bone or joint conditions.

Should women in perimenopause lift heavy?

The evidence supports it. In the LIFTMOR trial, supervised heavy resistance and impact training improved bone density and function in postmenopausal women with low bone mass, without increasing injuries.

How much protein do women over 40 need?

More than the basic minimum. Around 1.2–1.6 g per kg of body weight per day, spread across meals, is a commonly recommended target for active older adults building or keeping muscle.
