“I’ve been at Gym On Grim for several years now and I honestly can’t see myself training anywhere else. The friendliness and willingness to help of all the staff makes for a really pleasant atmosphere. Can’t argue with the rates either. Would highly recommend to anyone happy to listen”

“I have to thank MJM for all their support, I’m always greeted with a smile and hello, they offer on going advice and always willing to help out. They offer various different seminars and is always posting inspirational quotes, it’s a real family environment”

After joining MJM over 12mths ago, I’ve really turned my life around. I thought because I had an active job that was enough exercise for me. I was always tired and had little motivation to exercise. I now work out 5 days a week doing cardio and strength fitness , it’s my favourite part of the day.
