Fitness First Discount

Fitness First is a premium UK gym chain with over 25 clubs, roughly half of them in London. Unlike budget operators that charge extra for classes or restrict members to a single site, a Fitness First membership covers every class on the timetable and allows access to all clubs across the country at no additional cost. For anyone comparing gym options before joining, the combination of class breadth, proprietary fitness technology, and a competitive first-month offer makes it worth understanding what the membership actually delivers.

What Fitness First Membership Includes

BioAge Assessment and ablePro Technology

Every new member can receive a free BioAge assessment during their club tour. BioAge is Fitness First’s proprietary measure of biological fitness age — distinct from chronological age — based on a set of physical performance markers. The result feeds into ablePro, the gym’s AI-powered training platform, which uses Genius AI to generate personalised workout recommendations and Smart Strength technology to track resistance training metrics over time. For members who want more than a treadmill and a free weights area, this data layer provides a structured framework for measuring and building on progress. A personalised BioAge readout also gives new members a concrete starting point, which makes goal-setting more specific than the standard fitness-questionnaire approach used at most gym chains.

Classes and Training Programmes

The class timetable covers more than 30 formats across six categories: Performance, Cardio, Cycle, Strength, Reformer Pilates, and Mind & Body. HYROX-aligned sessions prepare members for functional fitness competition, while the Les Mills library — BodyPump, RPM, BodyCombat, BodyBalance — provides internationally standardised programming. Reformer Pilates classes across four formats (Tone, Align, Power, and Xpress 30) are included as standard rather than priced as an add-on, which is a meaningful saving compared to specialist studios. The app timetable lets members filter by category and book in advance, which matters at busier central London clubs during peak hours. Personal training sessions are available on top, with trainers who work alongside the ablePro system to tailor plans to each member’s BioAge data. For members who also take nutrition seriously, BudgetFitter lists deals for Bulk UK and Huel UK that pair well with a structured training schedule.

Club Network and Multi-Club Access

Fitness First’s UK network spans Baker Street, Clapham Junction, Oxford Circus, London Bridge, Balham, Brixton, Hammersmith, Queen’s Park, and Streatham in London, alongside Bath, Bedford, Milton Keynes, Oxford, Wigan, and Jersey. Multi-club access is included with all memberships, so members who commute between areas or change their routine week to week can use whichever club is most convenient on a given day without paying extra. The Fitness First app handles contactless check-in and class booking across the full estate. Clubs vary in their additional facilities — some feature dedicated cycle theatres, Aqua Run equipment, and Red Light Therapy — so it is worth checking individual club pages before selecting a home site.

Membership Perks and Referral Scheme

New members receive two complimentary guest passes valid within the first 30 days — worth up to £100 — and a 7-day cooling off period applies to all new joiners. The referral programme gives existing members one free month for every friend who joins, with no stated cap on accumulation. Student and Blue Light Card discounts (for emergency services workers) are available, alongside 100+ partner benefits including 20% off Healf and 15% off Under Armour. Payment options include direct debit, card, and Klarna installments. For those weighing up the full cost of a fitness routine, the BudgetFitter lists deals for Under Armour UK — a useful pairing since Fitness First members receive 15% off Under Armour as part of the membership partner scheme. Those who also use Les Mills classes independently can compare options on the Les Mills UK page on BudgetFitter.
