Day 9FollicularEnergy is climbing — a good window to push intensity

The problem

You are not inconsistent.You are cycling.

Energy, strength, appetite, and recovery are not flat across the month. When a training plan ignores that, the hard weeks feel like failure instead of what they are — a different phase.

The same plan, every single week

Most programs repeat the same blocks regardless of what week you are in. Your body does not run on that schedule.

Good days and flat days feel random

One week a session feels light. Two weeks later the same weights feel impossible, and there is no obvious reason why.

You blame yourself for it

It gets read as a discipline problem. Often it is simply your body being in a different place than it was last week.

How it works

Three steps. Then it runs on its own.

  1. 01

    Tell LUN about your cycle

    A short setup: your last period, your usual cycle length, your goal, your experience, and the equipment you have.

  2. 02

    LUN maps where you are today

    The app places you on your cycle and keeps that view current, so the plan is always built around the day you are actually in.

  3. 03

    Train with your phase, not against it

    Your daily workout, nutrition guidance, and recovery notes shift with the phase — heavier when it fits, lighter when it does not.

LUN is an educational wellness tool. It does not diagnose, treat, or replace care from a qualified health professional.

Inside LUN

One app for the whole month.

Workouts that follow your phase

A daily session built from where you are in your cycle, your goal, your experience, and the equipment you actually have.

Nutrition guidance by phase

Food ideas and general guidance that shift across the month instead of one rigid plan applied to every week.

An AI coach with context

Ask about training, food, or how you are feeling. It answers knowing your cycle, your goal, and your history in the app.

Teas and supplements, explained

Educational information on common options — what they are and what people use them for. Always with a note to consult a professional.

Mood, energy, and journaling

Log how the day went in seconds. Over time you see your own patterns instead of guessing at them.

Progress you can actually see

Streaks, history, and hydration tracking that reward showing up rather than punishing the weeks you needed to go lighter.

Informed by cycle research

Guidance is built on published work about how the menstrual cycle affects energy, recovery, and training response.

FAQ

Questions worth asking.

Do I need to know my exact period dates?+

No. An approximate start date and your usual cycle length are enough to get going. The more you log, the closer LUN gets to your actual pattern.

Does it work if my cycle is irregular?+

You can still use LUN — it works from the information you give it and updates as you log. If your cycle is consistently irregular and that concerns you, it is worth talking to a healthcare professional; LUN is a wellness tool, not a diagnostic one.

What if I use hormonal birth control?+

You can use LUN. Hormonal contraception changes the natural hormonal pattern, so phase-based guidance works differently — but the training, nutrition, and tracking sides all still apply to you.

Is my health data private?+

Yes. Your cycle, symptom, and journal data are never sold. You can export or permanently delete everything from inside the app.

Can I cancel whenever I want?+

Yes. Subscriptions are managed by the App Store, so you cancel in your device settings in a couple of taps. Access continues until the end of the period you already paid for.
