Mark Harris

Absolutely love this place. Went to 1st spinning and abs class Thursday for 3 weeks; the circuit abs was a great change and though it was a proper thigh trembler in spinning it was awesome! Love the way I feel when I walk out, like I’ve really done something. Thanks Tom (and Kim on Mondays) and everyone else there that makes I such a great place. Everyone’s always smiling, helpful and friendly


Cracking gym, staff very friendly and equipment is great. All at a reasonable price. Would definitely recommend


Well what can I say…I’ve been a member of definitions for about 2 months now and I can honestly say, this is the best gym I’ve been to, by far. Very friendly staff, up to date equipment and the classes that the gym provides are second to none.

Tonight was my first time booking in for ‘functional fitness’ and I can say I was pretty nervous as I walked in. However, the class was taken by a nice and motivational lad called Tom and i can say he really gave me that leap of faith to bust out one more rep. If you’re contemplating attending the class t any other….go! Don’t worry if you’re male, female, young or mature…the class is for everyone. Looking forward to Thursday’s session with jack…let’s hope my legs will be okay fro football Saturday.

Summer body….in progress.

Cheers guys.



Fantastic atmosphere and really friendly staff. Best gym I have been to and i have been to a lot!
