InTension Health Club Closed due to Coronavirus

As a result of the Corona crisis the Dutch government has decided that all sports and fitness clubs must close immediately. InTension Health Club also feels a responsibility to protect its members and employees. The most important thing over the coming time is that we all take care of ourselves and our loved ones.
These government measures apply to all areas of the Netherlands until April 6th.

We understand and respect that these decisions and measures are inconvenient for everyone involved. As an alternative we are offering you ‘Fitsnacks’ for free: 

This link offers you various training options so that you can stay fit from the comfort and safety of your own home.

You will receive the free login code for ‘Fitsnacks’ as soon as possible.

We will keep you informed of any further developments as they happen.

Warm regards,
The team at InTension

By getting in touch with your body in this way you can increase the understanding, softening and transformation of your body. You will experience what the vibration of sound and singing can mean for your presence and awareness. Singing the mantra creates flow.

In meditation you can experience how sound and singing contribute to clarity of mind and a keener sense of perception. The workshop will be concluded with a nice long relaxation exercise and will be musically supported on percussion and guitar! Are you curious about this special yoga and singing experience?
