Train with us free for a day. No obligation, class and gym access at our Newhaven gym! No pressure. No catches. You can try us out and see what you think. Take full advantage of the free day: join a class in the morning, train in the gym in the afternoon, then join another class in the evening! If we're a good fit for you, then 50% off joining fees if you become a member. There is nothing to stop you. Reclaim your health today.
You won't be left to work it out on your own. Our coaches learn your name, ask what you're training for, and are on the gym floor when you need them. First session or five-hundredth, same welcome.
Our classes are about more than just breaking a sweat—they’re about building a community. Whether you're pushing your limits in HYROX or having fun in Spin, you’ll find support, laughter, and maybe a little friendly competition.
With flexible class times that fit your schedule, it’s easy to stay motivated and inspired.
