Place your hands on your waist, cough, and as you do so feel the muscles of the waist pushing your hands outwards. Now press your hands inwards as much as possible but without feeling uncomfortable. Make a tiny contraction of the muscles you found by coughing and make them work as though against a resistance. Feel this tiny contraction in yourwaist; this is ‘inner support’.
Enlarge this support by contracting the muscles a little bit more. Eventually the muscles will push outwards against your hands. When this happens you have surpassed inner support.
