Until this evening the swimming instructors have been stressing that most of the power for freestyle comes from the arms. Today it was suggested to me that I should use my legs a bit more and that some drills would be useful.
Armed with two floats I set off to kick my way through a length or two. It was very hard work and showed quite clearly that I was barely using my legs for propulsion. Having said that, an online article describes how power is not a primary concern; the key thing is learning to not hinder progress with a poor leg action! I can relate to this as it was clear that during the leg drill my legs were higher in the water than when swimming with arm strokes. Low legs are a source of drag and I need all the efficiency I can get! I can relate to issues of foot flexion as during the leg drills I could feel my calf muscles becoming tight so I'm exhibiting typical runner's feet; more flexibility is stated to be beneficial yet again.
