Most fitness apps were built to make you feel behind. Solide wasn't.

Solide is a resistance training app built with women and non-binary people in mind, but designed for anyone who wants to feel strong, healthy, and capable for the long term. Not guilty for missing a workout.

The science is clear: regular strength training reduces your risk of osteoporosis, type 2 diabetes, depression, anxiety, cognitive decline, and early death. It is one of the most evidence-backed things you can do for your health. And yet most people have never been properly shown how to do it, or told why it matters.

That's the gap Solide was built to fill.

A FOCUSED EXERCISE LIBRARY
A carefully chosen selection of bodyweight, dumbbell, and machine movements covering every major muscle group, enough to build a lifetime of progressive training without the overwhelm of scrolling through hundreds of exercises you'll never use.

A SMART SESSION BUILDER
Solide builds a balanced session of 8 exercises, automatically avoiding anything you've already done this week and prioritising the muscle groups you've worked least. Change any exercise you want.

SCIENCE LIBRARY
Peer-reviewed research on muscle health, bone density, mental wellbeing, brain health, and longevity, written in plain language. Every article is sourced and cited. Understand the why behind every session you log.

BREATH WORK
A dedicated section of structured diaphragmatic breathing sessions, for stress regulation, nervous system recovery, sleep, and performance. Designed as a standalone practice alongside your training, not an add-on to it.

PROGRESS TRACKING, YOUR WAY
Log weight and reps with one tap. See your strength milestones surfaced quietly. No streak counter. No notification telling you how long it's been since your last session. Just an honest, private record of what you've built.

BUILT FOR LONGEVITY, NOT AESTHETICS
Solide has no appearance-based goals, no calorie counting, and no language about toning or sculpting. The single metric that matters is how strong and well you feel, now and in 30 years.
The app is clinically informed: resistance training has been shown to reduce depressive symptoms by up to 33% (Gordon et al., JAMA Psychiatry 2018) and significantly reduce anxiety symptoms.

DESIGNED WITHOUT PRESSURE
No mandatory programs. No streak counters that punish rest days. No guilt-coded notifications. You open Solide when you want to feel good. The app is here when you are, and quiet when you're not.
