I have trouble keep my hips high up at the water. I think it is mainly because of my kicks. My flutter kicks are also sometimes irregular such as when i kick at the right, only my right leg kicks at the right, my left leg is either dead or kicking flat. I remember hearing that when you see a swimmer high up in the water ( hips visible) , you know that guy is swimming very fast.
So i want to concentrate on my flutter kicking as it is such a HUGE factor in swimming. Now i seen some posts from internet that kick board kicking only improves endurance and not speed. Is that true or there are some drills which helps kicking?
