Swimming in sub-zero, possible?

Scientifically, and humanly, this is barely possible....perhaps, in split seconds only, or perhaps not at all. Frankly, it's hypothermic condition. Please don't try, only Jackie Chan, or trained stunt men with guided tricks (most probably some camera tricks with experienced directors and photographic directors), could do this. [insert: pic taken in seoul's one of the drinking holes, to give you that ge-ge-ge feeling, it's cold, my friend...! ]

What I wanted to say is swimming in colder waters like in airconditioned indoor swimming pools or swimming during winter time? I have seen people doing this, including myself good old days. Sometimes, dangerous because when submerged in the very cold water with head inadequately protected, this can cause damage to the brain work, so you may feel bit "giddy" or discomfort like whole head gets numbed feeling, and temporary paralysing possibilities to brain process and if prolonged into very cold water, the brain can just 'break down'. Normally, swimming in normally cold waters is ok, normally not a problem to anyone. Even in winter, say in Australia...is still ok, generally. But do becareful, if you don't feel comfortable if your heads are too long in the very cold water. Have fun...

Swimming strokes

I can show you all the strokes and the techniques that a good or champion swimmer uses generally in a competitive event. In the shortest time possible, with my coaching, you are able to master the strokes including breaststroke, backstroke, freestyle (front stroke) and butterfly, which you classify sequentially as relaxing, medium to power strokes. Other variants from the mainstreams are side-stroke, back-kick, and head-up. You will learn the basic techniques of moving forward efficiently (more speed, less energy) by use of a more streamlined positioning by optmising, head, legs, and hands positions. You will learn for each stroke, how to apply the various types of movement like scissors kick, flutter kick, dolphin kicks and frog kicks, among others And other forms of turning like flip-side, survival or rather water safety like backturning, and water-treading, by kicking, eggbeater kicks, and flutter kick, frog kick etc. And importantly,you will be able to swim comfortably, that is 'fly' in the water managing 50m, 100m, 200, to 400 m in the quickest time possible. You will gain good fitness in no time, and feel good whenever you are in the pool, of whatever size or depth!
