Back and Chest Stretching Protocol – BCS Protocol – was originally made to increase lungs volume in freedivers with great results.

The BCS Protocol consists of breathing and body stretching techniques and the use of the “bridge.”

Today it’s used to increase lungs volume for all sports, to correct postural problems and bad habits that nearly everybody in our society has.

It can also become a part of your yoga training and stretching section at the end of your activities!
