Bee the manager and Charlie the assistant manager of NRG are the best! As a woman finding a good gym that you feel comfortable working out is really hard, Bee is the one that help me from the beginning till now! The gym had two female zones and of course Bee is always next to me observing making sure I train the right way, as a manager she takes the extra mile and makes sure i always feel comfortable and That I always train the correct way!
Bee is actually the reason that I cancel my membership in another gym in Watford! Great person and an amazing professional! Asset for the company! Can thank

NRG is gym is fantastic place to train. Full of top quality equipment including an amazing functional area upstairs. A large range of classes which are led by welcoming and experienced staff. This gym also has a womens only area and also women only classes, which is a great benefit. The staff are all fun and lively and the management team is always very supportive. Bee and Charlie are always willing to help with any issues relating to the gym. There are many cleaning stations to help members clean up after using the equipment. Another benefit is it is open 24 hours, even over the festive period

This is the best gym in Watford town!! I've been training here years now, the staff are some of the nicest people. The equipment and services here are top tier! They have many classes to choose from if that's your thing, my personal favourite is the nrg boot camp. If you ever have any questions or queries don't be afraid to ask bee for one of the other amazing personal trainers.

After being a member for years I must say this gym is in such poor condition now it made me want to find a different one. Equipment always broken (stair master machines ALL broken for months now together with several other machines), the ladies only area has lost its only good piece of equipment which has been moved into the shared section (?! 99% of women wont feel comfortable hip thrusting in front of men). Staff absolutely uninterested in anything apart from building their own social media pages and taking mirror selfies. Next time instead of invesing supposedly millions into some new carpets
