We love to SDK. It's the 5th stroke. It takes skill, strength, flexibility, conditioning & mental toughness.
For many it's the 2nd fastest stroke, but it's not a legal stroke.
We wish it was legal. We wish there weren't 15 m restrictions in races.
We count our kicks because kicks count.
We train to SDK faster. Some call SDKs underwaters or dolphins.
What are you doing to improve your SDK?
How many do you take in each race?
Help! My SDK is Horrible! has many tips & a program to get faster.
Here's a helpful post in it.
What are your SDK times?
15, 25, 50, 75, 100, 150 & 200?
Spend some time in the SDK lane & you'll be kicking faster before you know it.

hey there
phelps has an excellent SDK and that slow motion video captures it well
he has more amplitude (up & down width of movement) and a
lower frequency (fewer SDK cycles per sec) than many swimmers
his DPK is quite impressive
he and many excellent SDKers keep their upper bodies rigid
I've written about the shin fin kicking technique
Tip 190 the Shin Fin Kicking Technique
Phelps has a bit of movement from his hips to his thighs, but it's mostly from his knee down.
He also has excellent flexibility in his:
1) feet / ankles (fins) (large flexible floppy feet are a plus)
2) knees (for hyperextension), &
3) shoulders (which helps his outstanding streamline which reduces resistance)
this video highlights his outstanding streamline & SDK

He's a great one to model your technique after

Thanks for posting this video, Ande. The one thing that caught my attention was that his body remains relatively rigid and straight. And it's as though his legs from below the knee act as a pair of fins- it's not just his feet. Maybe this is really obvious to most when they watch it, but I have seen this video many times and this just occurred to me.
