Still Trying To Glide? Check Out These Two Images

Who are the greatest female and male swimmers of all time? Undoubtably Katie Ledecky and Michael Phelps with 28 Olympic and 42 World Championship gold medals between them!

Check out these two underwater images of them in action at the same point in their freestyle strokes. They are both finishing one stroke at the rear and visibly starting to tip the fingertips downwards to start the next stroke at the front:

Why is that significant? Because in a single image each, we can see that neither of these GOAT swimmers is gliding - there is no perceptible pause between one stroke finishing and the next starting. Both Katie and Michael are smoothly transitioning from one stroke to the next down the lap.

Despite our best efforts, there are (still!) many swimming coaches out there teaching swimmers to pause-and-glide when they swim. This is a massive mistake as water is 800 times more dense than air and by pausing in your stroke you instantly decelerate before having to reaccelerate on the next stroke. An incredibly inefficient and ineffective way to swim!

When you watch elite swimmers on TV they can look they are gliding forwards through the water but this is an optical illusion brought about by the length of their strokes. The fact is they achieve that length through good streamlining and a great catch and pull technique, not by gliding.

You should follow the same philosophy in your own swimming, work on your stroke technique by improving your body position, becoming more streamlined and developing a good propulsion technique - transitioning smoothly and continuously from one stroke to the next.

By actively trying to glide you are trying to artificially lengthen the stroke - putting the proverbial cart before the horse.

Swim Smooth!
