Frequently asked questions
What is OnlyHands?
OnlyHands is a booking platform for supervised sparring sessions at partner gyms in Barcelona. You pick a session date, see who else is going, choose a sparring partner matched to your weight and level, and book your spot for 8 €.
How much does a sparring session cost?
A session costs 8 € flat. If fewer than 8 people book, the session is cancelled and you get an automatic full refund.
How are sparring partners matched?
Partners are matched within ±7 kg of your weight and at most one experience level apart. You choose your preferred partner yourself by browsing profiles for your session — matching is mutual, like a match on a dating app.
Do I need to join a gym to spar?
No. OnlyHands sessions run at partner gyms without a membership. You book a single session, show up with your gear, and spar under supervision.
Is sparring at OnlyHands safe?
Every session has a named supervisor on the mat, protective gear is mandatory, intensity is agreed before each round, and a tap or stop signal ends a round immediately. Partners rate each other's fairness after every session — unfair partners get filtered out.
Which martial arts are supported?
Boxing, Muay Thai / kickboxing, MMA, and BJJ / grappling. Each session lists its discipline.
