Bolt-ons are optional add-on features and benefits that help you get more from your membership for just a few extra pounds a month. Availability does vary from gym to gym - you can check which bolt-ons are available at yours on the gym's homepage. Bolt-ons include the ability to book classes further in advance, bring a buddy 4 times a month, and access Yanga sports water and hydro-massage chairs.
You can add the bolt-ons individually, or upgrade to the Plus membership to receive them all, on your Member's Area here.
The change will be immediate and a small amount will be added onto your next payment to cover the rest of this month's use of the new feature. The change, and your next payment, will be confirmed in an email afterwards!
