Freediving is the art of moving efficiently underwater on a single breath. The NTX training system has, at its core, a focus on ENJOYMENT & RELAXATION.
Techniques start with awareness & are suitable for everyone.


The health benefits are innumerable;

our techniques can relieve asthma, stress and panic attacks.


Training with NoTanx can gain improvements in all activities

e.g.  SCUBA, triathlons, Brazilian jujitsu, golf & more

As well as an exemplary safety record, we base our training on progression, with a proven track record.

It doesn’t matter what level you are at, or where you are aiming - Enjoyment is the key to long term progression.
