“I thought I just wasn’t trying hard enough.”

The problem

You weren’t inconsistent.
Your plan was.

Fitness was built on male physiology and handed to women with a pink coat of paint. No wonder it never quite fit. Insync starts somewhere completely different — with how your body actually works.

You train hard — and still plateau

Some weeks you smash it, others you can barely finish a warm-up. It feels random. It isn’t.

Your energy is cyclical, your plan isn’t

Strength, recovery and motivation shift across your month. Generic plans treat every day the same.

You’re told to push through fatigue

Fighting your body instead of working with it leads to burnout, injury and inconsistent results.

How it works

From hormonal data
to your next workout.

No spreadsheets. No guesswork. Just one intelligent decision, delivered the moment you wake up.

1Sync your body

Sync your body

Connect your wearable or log your cycle. Insync maps your hormonal phases into a living performance calendar — unique to you.

2Get today’s decision

Get today’s decision

Every morning, one clear call: what to train, how hard, and why — based on your phase, recovery and recent output.

3Perform in sync

Perform in sync

Build strength when your body is primed. Recover with intention when it needs it. Progress that finally compounds.

The science

Three reasons Insync
actually works for you.

A coach, not a dashboardDecision engine
Difference 01

A coach, not a dashboard

Most apps stop at data. Insync starts at the decision.

Cycle trackers and wearables hand you graphs and leave you to interpret them. Insync translates your biology into one clear instruction — exactly what to do today, and exactly why.

Hormones as your advantagePerformance lever
Difference 02

Hormones as your advantage

Not something to manage. Something to harness.

The world frames your hormones as a problem to cope with. We see a competitive edge. Train with your physiology and unlock strength, recovery and consistency because of your cycle — not despite it.

Built from first principlesFemale-first
Difference 03

Built from first principles

Designed for your body — not adapted from someone else’s.

Energy, recovery and output are treated as dynamic, not fixed. Every recommendation shifts across your cycle and learns from your real performance data. A system-level advantage, not a feature.

Four phases.
One adaptive plan.

Insync reads where you are and reshapes your training, recovery and intensity to match — automatically.

MenstrualDays 1–5

Active recovery, mobility and rest. Lower intensity — and zero guilt about it.

FollicularDays 6–13

Energy rising. Build strength, add load, chase progressive overload.

OvulatoryDays 14–16

Your peak power window. Go for the PR — your body is primed for max output.

LutealDays 17–28

Maintain and moderate. Prioritise sleep, fuel and technique over intensity.
