Hi, I'm 5'8 and I swim at a 25 yard pool. I can swim 1,800 yards in 42 minutes. Swimming freestyle, my right hand enters the water 12 times per length. I have read (www.totalimmersion.net/) that I should do 25 yards with 18 strokes (or 9 right hand entries) per length. What is the best way to reduce my strokes per length? Thanks! Don
