It's really nice after huffing and puffing through 70 laps, and feeling continually disappointed by my times, to be told by the lifeguard that I must be a "serious swimmer". I don't know what that means exactly, but it sounds positive.
We talked a bit and he said he observed that my technique is better when I breathe on both sides. Which I suppose is what my right shoulder has been telling me for a couple of years. When I only breathe on my right side, after a few days of swimming my shoulder aches like crazy.
However, when I breathe on both sides, I'm slower. Not by a lot, but some. Which is annoying since I'm slow right now anyway. So today I did about half my laps breathing on the right side and half alternating sides.
But the point is, out of the several people at the pool this morning (a couple of whom I thought looked really sleek), the lifeguard told me that I'm obviously the serious swimmer. Nice.
