Welcome to TIO CrossFit

About Us

TIO CrossFit is London's first outdoor CrossFit gym, based at Rosslyn Park rugby club in Barnes, SW London. We are committed to actively enriching the lives of our members and creating a community of likeminded people who love being healthy and strong. Our goal is to get you in shape while having a great time with nice people.

TIO stands for Train Inside Out - we love being outside and get out in the elements all year round (but have cover and heating for those times that the weather doesn't oblige!).

What is CrossFit?

CrossFit is an effective way to get fit. Anyone can do it. It is a fitness programme that combines a wide variety of functional movements. We do pull ups, push ups, squats, weightlifting, gymnastics, running, rowing and a host of other movements.

The community that spontaneously arises when people do these workouts together is a key component of why CrossFit is so effective. Harnessing the natural camaraderie, competition and fun of sport or game yields an intensity that cannot be matched by other means.


Our classes

All of our classes are group based and led by highly experienced, passionate coaches.


Fitness for Life

CrossFit can be used to accomplish any goal; from improved health to weight loss to better performance. It works for everyone - people who are just starting out and people who have trained for years.

Daily WODs

The magic is in the movements. Workouts are different every day and modified to help each individual achieve his/her goals. We will help you get fitter, whatever your age, experience or current fitness level.

Learn the Basics

CrossFit training is built on performing functional movements safely and effectively. Learn the basics in our foundations course and continue to be coached in every class as you progress.

New to CrossFit?

Welcome! The first step before joining classes will be to attend our Foundations Course. These sessions run across three consecutive weeks on Wednesday evenings 7-8pm and will teach you the basics of the movements that come up frequently and give you a taster of what our classes are like.

These small group sessions will give you plenty of opportunity to ask questions and we'll give you clear pointers on how to move safely and effectively.

The Foundations Courseis £60 or private sessions can be arranged on request.
