Comfort is key! Wear clothes you are comfortable to train in. People often wear shorts and a t-shirt, vests, leggings or tracksuit bottoms. Sportswear is ideal. Trainers or boxing boots should be worn for all sessions. Please don't wear muddy shoes inside the gym.
For boxing sessions (kids & adult) you will require your own boxing gloves and hand wraps. If you are participating in a contact session, you should bring a gum shield which is moulded and ready to wear.
If you are participating in sparring, it is preferred that you have your own head guard and groin guard.
Adults & Juniors over 50kg should wear 12oz/14oz/16oz gloves. You will not be able to participate in any contact exercises with lightweight gloves.
Children under 50kg should wear 6oz/8oz/10oz gloves depending on their age and size.
Please bring a drink with you.
Yes! Our full membership allows you access to the gym outside of class times. In this time you can use the boxing bags, ring, small gym equipment, weights and cardio machines. Our members are very friendly and considerate when working in the gym independently. A key box allows access to suit your schedule.
Often Tom & Harriet are in 1:1s & work appointments through the day - so not always able to pick up the phone.
We will always be pleased to return your call when we have a moment. It is usually the same day. Leave a message, send a text or email 🌟
Please do not call before 9am or after 8pm unless there is an emergency. The best way to reach us or request a call back after this time is via email.
