Official site lists a 3 Class Pass at £40 one-off, valid for 2 weeks, an Affiliate plan at £95 per month with unlimited classes and a 90-day minimum term, a Foundation plan at £50 every 4 weeks with 2 classes per month and no minimum term, and a £1 trial week. WodBoard lists the trial pass as 7 sessions expiring in 7 days. Third-party city research notes (source 11, citing Studiomaps and Gemini research) report drop-ins at £15.

Visitor Guide

Who it suits

CrossFit TBB runs coach-led CrossFit classes in Sydenham, East Belfast. Classes are scaled to each person, so beginners and visiting athletes can both train here.

Getting in

Start with the £1 trial week on WodBoard. The trial pass gives seven sessions and expires after seven days. Book each class in advance, because live class times run through WodBoard.

The floor and recovery

City research notes describe an air-conditioned training floor. Members can use an infrared sauna, a cold plunge, and on-site physio and massage. New members take a sauna and cold plunge tour with a staff member before using the hydrotherapy equipment.

Before you go

Sign the waiver during sign-up. Staff are not present at all times, so the gym is used at your own risk outside staffed hours. Check the Affiliate plan's 90-day minimum term before you commit to it.
