The Women's Guide: train with your physiology, not against it

Most training and nutrition research was done on men, then shrunk and coloured pink. Female physiology — cycling hormones, iron dynamics, menopause — deserves programming built around it, not around a male default.

This cluster covers phase-based training, the menopause muscle-and-bone defence plan, and the blood markers (ferritin, thyroid, sex hormones) that explain why energy and performance change across the month.

Part 1

Training with your cycle, not against it

Most training plans were built on male physiology and run the same all month. For half the population, hormones move in a predictable rhythm — and your programming can move with them.

Part 2

Training in the luteal phase: exactly what to change

The two weeks before your period are when training often feels hardest. Here is what actually shifts in the luteal phase — and the specific, practical adjustments that keep you progressing instead of fighting your physiology.

Part 3

Perimenopause blood panel: the 8 markers to demand from your doctor

Perimenopause is often dismissed with a single hormone test — or none at all. Here are the eight markers worth asking for, what each one tells you, and why the trend matters more than any single reading.

Part 4

Menopause, muscle and bone — defending both with protein and lifting

The menopause transition accelerates the loss of muscle and bone — but the two most effective countermeasures are firmly within your control. Here is the protein-and-training case, and how Misi tracks it.

Part 5

PCOS, insulin resistance, and lifting: a practical protocol

PCOS is at its core a metabolic condition, and insulin resistance sits at the centre of it. Here is the practical, evidence-based protocol — lifting, nutrition and the markers to track — that targets the root, not just the symptoms.

Part 6

"Why am I always flat in the gym?" Iron and hormones may be the answer

Persistent fatigue and stalled progress are often blamed on programming when the real cause is in your bloods. Misi tracks iron and hormonal panels that training apps ignore.

Part 7

Creatine is not just for muscle — the brain, ageing and the women’s case

Creatine is the most-researched supplement in sport — and the evidence now reaches well beyond the gym, into cognition, healthy ageing and women’s health. Here is what holds up, and one lab quirk Misi accounts for.

Part 8

Will lifting weights make women "bulky"? What the physiology actually says

Fear of getting "bulky" is one of the most common reasons women avoid heavy lifting. A 2025 review of the sex-hormone science behind muscle growth explains why that fear doesn’t match the physiology.

Frequently asked

Should I change my training across my menstrual cycle?

The evidence supports modest adjustments: many women tolerate higher intensity in the follicular phase and benefit from managing load, sleep and iron-rich nutrition in the late luteal and menstrual phases. Misi’s cycle engine adjusts training and nutrition nudges per phase automatically.

Why am I always exhausted in the gym despite training consistently?

For female athletes, low ferritin with "normal" haemoglobin is one of the most common and most missed causes — alongside thyroid and energy-availability issues. A blood panel answers in one draw what months of guessing cannot.

What actually protects muscle and bone through menopause?

The combination with the strongest evidence: progressive resistance training 2–4x/week, protein at 1.6–2.2 g/kg/day, adequate vitamin D and calcium, and impact or loaded work for bone. Oestrogen decline makes all four non-optional.
