I've been swimming for quite a while, and during my swims, my body generally favors the left side of my body. After swimming my left ab, leg, and my right arm would get tired out the most. Sometimes I have a tendency to drift to the left when I push off the wall on a flip turn or swim for that matter. When I closed my eyes for a brief moment while swimming, I world drift to the left, proving that something is wrong with the way I do my strokes. So I have a feeling that I've been doing these strokes the wrong way for some time now, and my streamline positioning is way off, and I might have asymmetrical muscle strength. So what can I do to correct this habit?
