Inside the gym
What's here, and who's here. Everything under one roof on Brighowgate.
The main floor is yours around the clock. Members get in with a QR code from the FitSense app — no fob, no card, no staffed hours.
A dedicated sports therapist and expert sports masseuse are based in the building, so the recovery side of training is not a separate trip.
Training hard requires recovery. The sauna and chill-out area are part of the gym, not a bolt-on.

Performance Lab have the best PTs in the area operating out of the building. The personal trainers are friendly and approachable and even if you’re not one of their clients will always offer advice and tips if you need them. Our motto is “if you need help just ask” and every member of our team will give you their knowledge to the best of their ability.

“A great gym with brand-new equipment and excellent facilities! As a member, you can also enjoy the sauna — a perfect way to relax after a workout. The monthly membership is very affordable, especially considering everything that's included. The staff are always friendly and helpful, and the personal trainers are highly experienced and professional. I've been a member since the gym first opened, and I'm extremely satisfied with all the services provided. I highly recommend this gym to anyone looking to join!”
“This gym has been a saviour in what could be classed as close to my darkest times. I struggle constantly with my mental health but this gym is so open, friendly, professional, never to busy to lend an ear. It has everything you need for a work out or if not working out, everything you need to chill out from sofas and a pool table to food and shakes. Also a barber and massage facilities. The weights and functional training area are great and the assault bike is the work of something ungodly haha but well worth the pain with the full body workout you get. The guys there are great and it feels more of a family there than just a gym. Highly recommend, with top class professionalism and plenty of banter. Not just my gym, OUR gym. Thank you Performance lab”
“As someone who uses the studio on a weekly basis. I have nothing but amazing things to say! They have enabled me to grow my personal fitness business whilst helping to promote my content. The staff are all so friendly and attentive, the space is always kept in an immaculate condition. The gym is open 24/7 which allows access for members and class participants to enter at any time. The QR entry has made hiring the studio quick, easy and a safe environment to be in! Still availability for studio hire if you are looking to for a space. Contact them now via socials for more info. Highly recommend!”
“After being at sub par gyms in grimsby and cleethorpes this is by far the best round with advanced kit and machines that are well maintained aswell as cleaning stations available, the atmosphere is calm and the staff are always more than happy to help and share their knowledge in relation to fitness and nutrition.”
“This is a great gym, open 24:7. It's safe, welcoming and the members are all friendly. The staff are knowledgeable and really helpful. I've been a member of commercial gyms, and this one beats them hands down. The sauna is nice addition too. Highly recommended.”
“I couldn't recommend this gym enough to anyone looking for top-quality equipment and great staff! Since joining Performance Lab, I have been impressed with the quality of the equipment available, It has everything I need to keep my workout varied and challenging.”
