More than half a million pounds is being invested into Nuffield Health Fitness and Wellbeing Centre in Guiseley.
The eight week project will see the overhaul of facilities and equipment and the addition of a clinic.
A new Wellbeing Membership is also being launched, giving people one-to-one support from a Health Mentor as well as four individual sessions with either, a physiotherapist, physiologist, personal trainer or nutritionist.
The upgraded facilities include new washrooms and a steam room, a cafe, new cardio vascular equipment, and a clinic.
Richard Beaumont, general manager, said: “Our commitment to helping people to improve their health and fitness is our priority.
“We are confident that our state-of-the-art facilities, coupled with the very best expertise of our health and fitness professionals, will ensure our members have the best chance to achieve their health and fitness goals.”
