Different frog kicks

[BlueTrin]

(I posted this in another thread but followed someone’s advice to create my own thread)

Are there different frog kicks ?

If you compare these two videos the level of the knee is much lower in the first video:

Then in this one the legs are more bent keeping the fins higher. Possibly to avoid kicking silt ?


If I was looking for the most efficient frog kick to lower my air consumption, does it make a difference which knee position you use ?

I think I am gonna try to record myself in a pool to get some visual feedback. I think my technique needs improving: an instructor told me that I was doing frog kicks with my feet raised, which is good for not raising as much silt, but my technique isn’t correct and I am not getting enough propulsion for general use. She advised for me to focus on fully extending the leg.

Yes, the first video is a horrible frog kick.....second video is proper. Why? When dropping the knees it pushes water forward reducing efficiency and increasing drag. There really are only 2 frog kicks.....the frog kick and modified frog.

You're basically going to be keeping your body flat, or ever so slightly arced upwards, from your shoulders to your knees, with your legs up. You shouldn't be straining your back, but you'll be feeling a little tension in your glutes when you do this. The kick will vary from using your legs as shown in the second video, to just a tiny kick using your ankles only. This position will also set you up for the back kick, helicopter turn, or modified flutter should you need a burst of speed. If you're actually balanced and flat, you will easily be able to go a little head down and back up and away from something directly in front of your nose.

Hi Bluetrin. Very difficult to give objective feedback from a written description so if you can get someone to video you that would be great. Maybe also show us your 'natural' finning technique, i.e what happens when you're not consciously thinking about it.

Sometimes I think people are too concerned about doing what they perceive as the done thing rather than tuning their existing method.

I for one know my frog kick is shite. I can do it, but it just feels awkward after a while. My natural fin is half frog kick and half corkscrew. However it gives me plenty of power, doesn't wear me out, and doesn't disturb the silt.

Anyway, enough about me. Good luck and looking forward to the vid.

corkscrew

Huh?

In regards to the videos, i would discount the first one, for a few reasons. Second video is spot on.

To work on technique, a shared video of yourself will get the folks on here with much more experience a chance to give you the detailed information you are looking for in reference to your personal kick.

Think.....hmm? Riverdance!

You can feel when you have good thrust forward when you are frog kicking correctly and have maximum pressure against your fins

So frogkick but with one leg at a time?
