Our lead personal trainer has more than 33 years of personal training and fitness industry experience and is an Internationally recognized personal trainer for his detail oriented style and focus on technical  and postural perfection.

We train people both privately and in group settings.  Our primary focus is to help each client reach his or her goals safely, efficiently and in an educational manner.

Our training is for a mature Expat demographic who want a more private, exclusive one on one setting in which they can learn the finer points of correct exercise techniques and achieve the results they desire from one of the the most experienced personal trainers in the world, without all of the kiddy, night clube-sque booming music emminating from a room full of  group class followers on the verge of serious Lumbar 5 injuries due to a lack of attention from an instructor screaming into a headset.

Our Fitness Training Studio

We have a fully stocked fitness training studio complete with outdoor jungle gym, multiple depth pool and a grass area which is perfect for yoga or cross training.

Give us a call and we'll set up a tour so you can see how great training at our gym really is.

People Are Saying Great Words About Our Fitness Training

"I wasted my time training at two fitness training studios on Sukhumvit doing the wrong exercises.  Those inexperienced personal trainers had me doing exercises which made my back hurt worse and which didn't accomplish my goals.

This is the kind of fitness training I should have been doing all this time.

--Anand, Bangkok

"I'm learning how to train efficiently while accomplishing my goals.

One of the benefits of training with Dennis is that he teaches me the most intelligent exercises and he structures the movements so the workout is efficient.  I'm training more effectively and get more done in half the time.

--George, Bangkok
