Master's Swim

I had a one hour one on one swim lesson tonight with the master's coach because only three people came tonight.  It was great.  Here's what I focused on.
1.  Keeping my head down (looking at bottom of pool
2. Entering the water and then reaching, using my arm pit to move the water, that throwing the water out of the pool.
3. Using a little tow kick with each stroke to keep my legs up.

Before the night was over, I had swum a 50 yard sprint in 37 seconds.  (That's without a flip turn.)

Not bad for an old shark.
