Speedo – Breast stroke fins

Last Thursday I already took my new Speedo Breast Stroke fins for a test run. I was actually surprised by the amount of propulsion it produced. I did a few 25 meters DNF to see how propelling with my legs was exaggerated to a level I became aware of the way it should feel.

As I’m still finding my way through the proper technique and the helpful tools to get rid of my scissor-like leg movement, Kostas joined me last night with another helpful tool; the video-camera. Looking back at the footage right after I did the 25 meter test runs, made it more obvious I needed to lower my right leg even more.

As a comparison we made a few clips where I did a run with:

  1. initial technique without the speedo fins
  2. corrected technique without the speedo fins
  3. initial technique with the speedo fins
  4. corrected technique with the speedo fins
  5. corrected technique after use of speedo fins

When reviewing the footage some interesting facts grabbed my attention. In relation to how it felt whilst doing the different test runs, I can say that even though you wear the fins, I still need to be paying attention to the lifting of the right leg. When applying the force with the legs, the moment of ultimate propulsion at first seems to be short. But after re-capping the things William said in his course you can keep the propulsion going by scooping more water, by pointing the toes inwards at the end.

My scissor isn’t gone by long, but getting aware of the fact by reviewing the footage is very helpful. Another thing which makes me aware is by looking down at my legs whilst swimming… it’s not the most elegant way, but then I seem to see the errors and correct them instantly.

The next few weeks I’ll be swopping between my DNF-technique and the DYN monofin technique.
