Dolphin Kick on Back
 

Hello Everyone,

I'm doing the following two dolphin kick on the back drills solely for exercise purposes:

head-lead

hand-lead
https://www.youtube.com/watch?v=udLi7ZZ4aOo

Can anyone perhaps tell me approximately what's a reasonably efficient number of kicks it should take to get from one end of a 25-yard pool to the other end for both the head-lead and hand-lead drills?

I just want to get an idea of how good or poor my current technique is.

Thank you,

Peter
