ثالثاً: سباحة الظهر ( Back crawl ): في سباحة الظهر يقوم السباح بالاندفاع من الحائط عند البداية على ظهره

The back crawl is different to most strokes because you cannot see where you are going.
It is a good idea to count how many strokes it takes you to swim a length so you will know when you are getting close to the end of the pool.
Try and swim with all of your body close to the surface of the water, almost like you are lying on your back in bed with your head on a pillow.
