Freestyle - Flutter-Kick Basics

Posted by Glenn Mills on Aug 18, 2009 09:15AM (45,151 views)

Depending on the type of swimming you're doing... competitive, fitness, or open water... the ability to control your legs, and keep them productive, is very important.  Here are a few key things to keep in mind as you work on your flutter kick.

Why Do It:
No matter what kind of swimming you do, working just on your kick can give you a more rhythmic and productive stroke.  The ability to turn on, or turn off your kick, can also make the decisions of saving energy, or gaining velocity all yours.

How to Do It:
1. 
 We'll start with the basic kick, on a board.   Some people will argue that using a board teaches incorrect body position.  While that may be true, this drill is all about being able to focus solely on the feet, and taking away that need to go to air allows you to focus more.
2.  Many people have been taught to kick with a straight leg, like this.  Please don't.  While it may feel like you're working, which you are, you won't be moving forward.
3.  Instead of keeping the legs straight, think of snapping through the end of the toes and allow the knees to bend just a bit to allow for that snap.
4.  Many runners and triathletes have ankles that don't flex very well, and the more they kick, the slower they go.  Two quick options for this.  Keep your feet HIGH and within the shadow of your body (a wetsuit will really help with this), or start working on your ankle flexibility and focus on pointing your toes.
5.  People who think they get all their power from their thighs tend to try to set up the entire kick like they're riding a bike.  Remember:  The resistance you create in setting up the kick must be overcome with the propulsion you generate.  The solution for this... keep your kick small, and don't create resistance with your thighs.  Kick from your hips, NOT from your thighs.
6.  If you want to continue to work on your kick, AND your body position, grab a Finis Swimmer's Snorkel.  You can continue to use the board if you need it, but hold it farther out in front of you, and place your face in the water.  If you feel comfortable without the board, just hold your hands in front about shoulder width apart.  Continue keeping the kick small, and now you can watch the bottom to see your forward movement.

How to Do It Really Well (the Fine Points):
Keep the kick quick, and small.  Try to keep the knees from going too deep, or outside the shadow of your body.  Think small when you kick, and remember to point your toes.  Finally, don't allow your feet to go too high out of the water.  Most of the bubbles you see here, are caused by the heals sucking air down... rather than the front of the foot pushing air down into the water.

Can you explain more about(or how does it feel) "Kicking from the Hips" please! Thank You!

Next time you get in the water, focus your attention on your hip flexors when you kick, then tell us what you felt. You may be able to explain it better than me... but I do know if I think about it, I start the kick higher in the leg, and don't expose so much of the thigh to the water. Jason Lezak explains it well on his DVD as well.

Glenn, could you explain the last sentence "the bubbles are caused by the heals sucking air down" ? Where is the front of the foot : above ?

Responded Aug 19, 2009 11:36AM

Watch the vid a bit more closely... you'll notice the front of the foot doesn't rise above the water.

Fantastic video, thanks! I only learned the crawl as an adult (raised on good old fashioned breast stroke) and searched high and low for a comprehensive basic video (or book or anything) on proper flutter kick. This is exactly what I've been looking for all that time. I am, indeed, concerned that the kickboard will interfere with my body rotation (again, adult learner), but I suspect that, after a few rounds with the kickboard, I can easily transfer the focus points of this drill into skate drills. Thanks again.

Nice video Glenn. The examples given are showing the swimmer(s) kicking at a low intensity. Just curious when the tempo is upped - how much of the foot comes out of the water then?

Responded Aug 19, 2009 06:53PM

Hey Billy. Watch the Kara Lynn Joyce video, and she'll tell you she does just about ALL her kick training with her feet under the surface. The technique of just allowing the heels to draw the air down, does allow for some faster foot speed though... so keep that in mind.

Karen... kick is kick. Don't be afraid to use the board to isolate the movements of the legs. There are far too many people out there who get others "afraid" to use the tools that are out there. If the tools are used properly, and in moderation, they allow you to really think about JUST that singular move... and not have to worry about anything else. Grab a board, and have some fun. :)

Now Glenn, you _know_ I haven't gotten KLJ's DVD yet (sorry). But yes I watched your promo again and paid attention to her board kicking.

As for a board, I really like (kicking with) my board, I've got one of those Speedo Elites from a couple of years ago. It's really light, so it allows me to streamline better with it. I have to say I _used_ to be one of "those" that disparaged tools such as pull buoys and kick boards. But these days I love to use them, at least when they are used for a specific purpose.

Oh, no I don't think kicking is fun - it's something that makes me realise how old I am!

Responded Aug 20, 2009 10:27AM

Glenn, would you say that a good kick comes from : a) toes pointed and knee-to-toes as stiff as a stick - b) kicking a ball with the front of the foot c) a whip lash performed with the toes ?

Responded Aug 20, 2009 01:09PM

Hey Camy. I'd say avoid anything in swimming that includes the word "stiff". Swimming flows, especially when you're talking about the feet. You're closer with B and C... I especially like C, as it gives me the impression of QUICK, or FAST feet... the feet achieving some velocity in the movement. At least for me... keep thinking that way.

Billy, I generally use a small board too, but I like the big boards for flutter kick as I'm not too good at it and I need the air. :) I'm old, so I'm allowed to "cheat".

I wish I kick normally but cannot due to right leg/ankle problem grr you have NO IDEA how angry and annoyed I am. Felt like chop my right one off. On Monday I go to see doctor to see what went wrong

THANKS GLENN!!!

When I tried Kicking from the hips, I noticed my legs got a little more stiff. I also feel my hamstrings and quads engaging more too.

Responded Aug 22, 2009 11:12PM

"Keep the kick quick, and small". I kept this in mind this morning while I trained and I really noticed the difference. I was able to improve my speed. Also my lower back and hip joint were not as stressed and for me it is a real plus as my sacroiliac joint is almost out of commission... Thanks:)
As far as the board is concerned I have switched for an Aquadisc which help staying streamlined.
Now any recommendation when you train with fins?

More positive feedback--I'm also someone who learned crawl as an adult and this video is the missing link for me in trying to refine my flutter kick. Really, really helpful and well done..

I FINALLY "felt my hips" after a 5x400 Free set. It was probably the fourth 400, and I think I finally "felt my hips" because my legs had gotten so tired. Relatedly, the Free leg of my IM's always feel like my Freestyle is the most "natural" (because I am so tired on the fourth leg of the IM). So, I know I'm not saying HOW to "kick from the hips"... but my insight is that maybe if you get tired enough :-) ...then you'll put your body in a position where it will NEED !! the big muscles in your hips in order to ... "kick from the hips". Eg, I always interpret "kick from the hips" to be a shorthand for "snap your ankles, thighs, and hips like a whip"... and a whip is snapped from the handle... which are the hips... and the end-of-the-whip is the toes. So, again, I was always so focused on snapping my ankles that I never allowed my hips to have a chance; 'being very tired after 1600 yds meant that I kind of let my body take over... and my hips "volunteered" and started to assist in the kicking. Also, when I kick-from-hips... I now feel like my Core is higher in water. I hope this helps!

Great video and explanation. I have heard "kick like you are kicking a soccer ball"; but I can't kick a soccer ball either. I can see in the video how the swimmers kick from the hip - that is the missing piece for me. I also liked how you offered a solution for swimmers with stiff ankles. I fear mine will always be on the stiff side of the spectrum - despite working on ankle flexibility. That's just the limitation of my particular set of ankle joints - they will be stiff - less stiff with work, more stiff without it.

Glenn & Rachel - Another great swim video. Just when I was going to minimize my freestyle kicking, you convince me to try new techniques and drills. Thank you.

Thanks a lot Glenn, I hope to got the oppurtunity to meet you and learn in reality
