Your strongest years are still ahead

Rebuild strength
properly

STRNTH is the strength training app for lifters in their 30s, 40s and beyond. Structured programmes with progressive overload built in, and proof you are getting stronger.

The difference

Progress you can see from week one

01

Your session is ready when you open the app

You do not have to decide anything. Exercises, sets, reps and weights are laid out before you lift a finger.

02

The app tracks every rep, week after week

Every session builds on the last. Weight increases automatically as you get stronger.

03

Logging a set takes two taps

Tap weight, tap reps. The set is logged without breaking your flow, and a full session takes seconds.

04

Check in and the coach tells you what to do

Green means go, amber means ease off and red means rest. Every signal is built from your own training data.

05

The numbers tell you it is working

Your STRNTH Index climbs session by session, alongside your personal records and strength trends. The proof is right there.

06

Everything is handled in one app

Workout planning, coaching, body tracking, HIIT and recovery all live in the same app.

More than a workout tracker

Six areas, one app.

Workout

Your session is waiting before you get to the gym. Nothing to scroll through or decide.

Coach

Every session you log teaches the app something about you. This is where it talks back.

Body

Your weight tells one story. Your body composition tells the real one.

Programmes

A programme that gets harder as you get stronger, rather than a flat list of workouts.

HIIT

Interval training that tells you exactly when to push and when to rest.

Community

A library of programmes and HIIT sessions built by other members. Publish yours, clone theirs.

Questions we hear most

“I already know how to train”

STRNTH adds structure to what you already know, and the tracking shows you the blind spots.

“I want something that grows with me”

The analytics and custom programme builder give it depth that scales to your level.

“I don't want generic AI”

The AI is trained on strength principles, not random fitness content. It suggests, you decide.

“I need proof this is working”

The proof is in the app: charts, personal records, weekly summaries and body metrics.

“I don't have time for friction”

You can log a set in two taps and start a workout the moment you open the app.

“My body doesn't recover like it used to”

Age-aware programming and recovery tracking are core features, not afterthoughts.

“I haven't trained in years”

The onboarding sets your starting point. Weights and intensity match where you are now, not where you used to be.

“Do I need to know about lifting to start?”

No. Every session tells you what to do, how much weight and how many reps. Just follow the plan.
