Tonal

Tonal makes smart home gym equipment built around digital resistance technology. Its compact, wall-mounted system delivers adaptive strength training and full-body workouts, with intelligent weight adjustments made in real time and advanced lifting modes that the company says can help members build muscle up to two times faster. The hardware is paired with a membership that offers guided programmes, real-time coaching, automatic progress tracking and a library of science-backed workouts tailored to each user's strength level and goals; one membership supports unlimited accounts per household.

The underlying engineering spans several domains: artificial intelligence, digital resistance, adaptive weight adjustment, computer vision for real-time coaching guidance, and personalised training algorithms. The product is designed to serve everyone from fitness beginners to professional athletes, and to fit into homes where floor space is limited.

Founded in 2015, Tonal operates in the connected fitness and health-and-wellness sectors. It has raised more than $535 million and was valued at $1.6 billion, giving it unicorn status. Millions of workouts have been completed on the platform to date.
