I'm interested in learning different ways to stretch my ribcage and diaphram to assist with deep equalisation. Would some of you deeeeep guys and gals give me some tips please. Also any advice on empty lung training routines. I'm currently doing both these things and would be grateful for some input from those who've had more experience, to learn different methods. I hadn't realised quite how important this flexibility issue was until I took the sled well past the point of my lungs feeling completely empty. I've always hated stretching and am very inflexible at this time. Claude Chapuis attributes his inability to equalise below about 67m to his ribcage stiffness, even though he can stay at depth for ages, so I guess it must be important. Can anyone offer any advice please?
