I was looking to learn the basic of crawl having struggled to manage in water with a very weak breaststroke all my decades of life, I found the instructions from Adam exemplary and was quickly able to establish when my movements in the water were natural and felt easy.
Kudos to the teaching here as it was explained very simply and backed up by video analysis as to my +s and minuses and they were quickly pointed out and corrected.
Absolutely first class teaching and I am eager to practice regularly in order to swim competently in the sea this year.
