    *Additional Fees

    Joining Fee: A joining fee may apply to your membership. The joining fee is an important part of the clubs success, it means we can keep monthly subscriptions lower whilst not tying you into any long term contracts giving a lot more flexibility than other establishments.

    Club Enhancement Fee: Once a year on the 1st of May, everyone pays a club enhancement fee of £19.00 (£10.00 for youth members). Your direct debit will increase for this one month and then revert to your normal monthly fee. This is invested yearly into club improvements. Any memberships bought in April and May will not pay the fee for that year.

    Multi Site Access: This means your gym membership can access Brighton and Newhaven, Tunbridge Wells.

    Pay As You Go

    We also offer pay as you go options on gym sessions and our classes if you ever want to just drop in.

    • 1 Session £8.00

    • 5 Sessions £35

    • 10 Sessions £60
