Swim swim swim

Though I've mostly just been kicking around in the pool, my arms are very exhausted really that now as I'm heading home from my first crawl-lesson. It's been nice even though it felt a bit too crowded in the pool.
Today we mostly focused on how to properly kick with your legs in terms of physical movement and whereabouts to lay in relation to the surface. 70% underneath and 30% over. Your  heals should reach above the surface when kicking  in case anyone reading was wondering.
My body feels like spaghetti now and I hope to sleep like a baby once I'm home.
