Sand. It’s coarse and rough and it gets everywhere, but that shouldn’t stop you from learning to swim, it can be made easy. Start by practicing floating and familiarizing yourself with the medium. Being at ease is essential, so stay wherever the waterline reaches your shoulders. Breathing is an important part of the ordeal, because full lungs keep you afloat. Breaststroke and sidestroke are good starting points, whichever resonates more with you. Personally I think sidestroke is better because it’s very smooth and the body falls quite naturally into this position (look it up on youtube for tutorials, it’s very simple). Last but not least, we learn by playing, so have fun. 😀
