For a brighter future

Free for teens!

We want to inspire our young to fist-bump each other for their physical achievements. Enabling them to get better at packing their bags.

So we made the Relentless Trainer free for everyone until the day they turn 20.

A growing community of boost

Squat with your squad

We strongly believe that community, training buddies and friendship helps build stronger, healthier bodies and minds.

Working out together makes the grit less gritty and the grind less grindy. We will always prioritize this for the sake of you and your community.


The training industry is broken and we are fixing it, one data point at a time. We’re all done with generic programming.

– Marcus Herou, founder & CEO
