Hey, I'm taking a class and before the class I was only doing 45 second breath holds on the couch and my last attempt in the water with my instructor was 2:05 a week later. It sucks but hey its improvement. When I was doing static apnea I kept having to swallow (I wasn't opening my mouth and swallowing water). I guess I was getting a throat closing sensation and wanted to clear my throat. I tried to stop swallowing but its hard not to. My instructor said he hasn't had any students do this before. Has anyone else had this issue? Any tips? I know I should be able to go longer because my instructor said I'm not huffing and puffing when I come up for air. Thanks.
