Gains AI

Gains AI, operating as Gravl, is a fitness technology company founded in 2021 and based in Bondi, Australia. The company provides an application that functions as an AI-powered personal trainer, delivering customized workout plans for users aiming to build muscle, increase strength, or get lean. The business operates on a subscription-based model, offering both free and premium access to its mobile application, which is available on both Google Play and the Apple App Store. Gravl also runs an affiliate program, allowing content creators to earn a 40% commission on subscriptions they generate.

The core of Gravl's service is its proprietary AI algorithm that creates personalized and adaptive training schedules. Unlike applications that assemble random workouts, Gravl's technology analyzes a user's attributes—such as gender, weight, age, and training level—along with their workout patterns, equipment availability, and fitness goals to design evolving plans. The system is built on the principle of progressive overload, automatically adjusting intensity, volume, and weights for subsequent sessions to ensure continuous progress and prevent plateaus. It also considers muscle fatigue to target recovered muscle groups, aiming to optimize each workout for effectiveness.

The app features a library of over 300 trainer-led video demonstrations to guide users on proper exercise form. A key feature is the "Strength Score," a metric that measures a user's strength and progress based on eight sub-scores and millions of data points from peers of similar demographics. Users can either follow the AI's recommendations completely or customize various settings, including their fitness goals, muscle splits, and workout duration. Additionally, the platform offers in-app support from coaches for workout advice and assistance.
