I don't see what your not getting - we know it is a short process in theory, but people take the pee and faff about. It is abit extreme to say how so important it is to have a drink every 2 minutes... and the magic sponge effect is great for youngsters just like saying the light stops monsters getting in the room, but for an adult your just wrapping them up in wool, losing discipline and regement in the class, and a fighting spirit to push through it.

1 hour class: drink before class, a drink after warm up / stretch after 15min, then a drink after pads 10min before end and then finish with whatever (conditioning, stretching) and another drink... and drink in moderation for the rest of the evening. I don't see how this is going to make someone suffer and collapse. God help them when cutting weight on fight days.
