"Best gym in Hull by far (for bodybuilding and resistance training in particular). Has everything you need, and more. I paid for a month and once that is up, I'll most likely get the 12 month contract. Great atmosphere too. Other members actually put things back here, and properly so you're not fatiguing yourself by unracking or putting weights back for other people. I feel quite lucky to have this gym in walking distance."

"THIS, IS, ULTRAFLEX!! We visited ULTRAFLEX Hull for the third time today completing two sessions - legs before lunch, and then upper body in the afternoon. We were blown away when we visited the gym last month, and we couldn't wait to return. The gym is modern, filled with high-end equipment, and has a great clientele. The staff are friendly, approachable, and really helpful. The only thing stopping us getting a monthly membership is logistics, or we would definitely be signing on the dotted line. See you again soon."

"Amazing gym, staff are helpful and know what they're talking about and the equipment is all high quality and easy to use."

"If I could award more than 5 stars I would. The gym, staff, equipment are second to none. I have only been in for a few days and it's always spotless with never a weight left out of place. Everyone is friendly and willing to help. Changing rooms are clean and fresh, what more could you ask for? Definitely recommend to friends, keep up the good work guys."
- Katrina Henderson
"Great gym with loads of quality machines, free weights and squat racks that's reasonably priced. Plenty of space even at peak times. The recovery room is a great feature as well. I was very impressed. Will definitely use this gym again if I'm in the area. Really impressive."
