Swimspecific Core strenghtening in the pool
 
I still think this is a brilliant idea to strengten, and learn, the core aquatic skills. especially for activating muscles you normaly dont use much. Also for locating the right muscles used for kicking from the hip and not the knee.

Some Ti coaches have said he is driving the rotation with the arms, but its the opposite. . The legs lead, the arms follow. He is driving the rotation from his legs.
Only when arms come above water weight is pushing them down, and then thats hard to hold with the legs.
Thats some fractions in time where arms starts to lead rotation.

Actually, his core body movements are being driven by both his arms and his legs, and it's impossible for anyone to say what percentage is arms and what percentage is legs. That's why a drill like vertical kicking is so useful: By having the arms do nothing, swimmers can insure that their core body movements are being driven entirely by their kick.

Thats true.

Still like it because it teaches the transmissing of force from hip to shoulder, the bracing of the shoulder against the hips.
This teaches not to rotate the hips disconnected to the shoulders.
And it gives the trunc muscles awareness of the rotating axis.

Hello ZT,

Hmm... not sure about. Have to give it a try. Just from watching, I think it forces a diagonal kick to the opposite arm to catch (if we do). But what we do need is a well timed kick to the catch or (when timed a little later) to the press phase on the same side. Diagonal we do need the kick for supporting the spear. But just for trimming the right muscles and the awareness of couplings/connections it may be good...

Best regards,
Werner

I think this drill could help imprint the simultaneous timing/coordination of the 'down-kick' with the 'down-spear' in the opposite arm -- at least for those beginning to learn 2-beat kick.
