Pilates with WillPower Method Classes

Pilates WillPower website

We went out to see if we could increase our knowledge of any new developments which will improve our classes and make them even more effective and fun for you.
Our intention was not to remove the existing program from our timetable but to improve it as we know that the current program is an important part of our well-being for life.We think that the addition of Pilates to our classes will do this for you.

Below is an introduction to our new Pilates class which has a twist on our existing class.This class will be starting from September alongside of WillPower Method. We believe that the costs of our classes are the most affordable in South London and that our regulars really do benefit greatly from them but, to cover our ever increasing overheads, there will need to be a slight cost increase for our classes this Autumn.The increase will be from £5 to £8 per session but will be for the new and improved specialised Pilates/Willpower Method class.

The price of our junkie card, which is the pre-pay option, will remain the same - £40 for 10 sessions.

Our new foot-fitness conditioning program - Willpower Method® - was a massive hit and you girls have not stopped talking about it! Therefore we have taken the decision to continue running classes until the end of the month.
