One Good Turn Creates Another… 
Look to the start to correct your delivery errors

I spent last Friday watching 7.5 hours of discus at the Mt SAC Relays in the 90 degree sun.

A curious thing struck me while seeing throwers and their coaches communicating to each other from the stands and the infield with arm, hand and body gyrations and a few short words.

Usually they were showing how the left shoulder was pulling down and away during delivery.
Sometimes the coach’s upper body would jack knife forward indicating an upper body throw.
Then they would stop and push their right hip ahead of the shoulder indicating the correct delivery.
Occasionally the thrower would indicate a scooping motion with the arm.

But… They were all focused on the delivery of the discus. 

No one focused on the start at the back of the circle! 


The start is where the errors are generated.

Fix the back and the delivery will be correct.
Pulling away on delivery is the result of being off balance to the left at the back of the circle, NOT fighting too hard at the front with the left arm.
It’s a natural consequence, you can’t avoid it.

If you are ON BALANCE at the back it will be very difficult if not impossible to deliver incorrectly.
If you are OFF BALANCE at the back it will be very difficult if not impossible to deliver correctly.

What you do at the Back 
of the circle

you MUST Repeat at the Front

Eliminate the Root Cause of the Problem 
at the back of the circle.

Where is the discus?

150 minutes for the final.
The cage looks low and the opening wide.
The original plans called for a roof over the stadium but it wasn't added until years later.
In 1979 the World Cup was held here on synthetic turf.  
The hammers bounced like 16lb super balls.
It was almost a spectator event!

Montreal Olympics 1976

The discus is just over the rim of the stadium above the first light to the right of my back.

Retired Thrower in the Park

Does the blade have to stick to make a legal throw?
Concordia Thrower's training gets a little diverse due to Mac's short attention span.

The Power of Conservation of Rotary Momentum

This is a key part of throwing far.  You must accelerate the rotation of the hips in the middle of the circle and minimize the loss of any rotary momentum during delivery.  Shortening the right leg is how it is done.  Note the skater's long left leg merely shortens and the rotations increase in speed.

Krishna Poonia 62.25m W-DT
Makes Olympic 'A' Standard 62m
Pretty Good for short season and 3 months of heavy training in Portland.

Going Slow at the start is the hardest thing to do in the discus.
More efficient technique is required for London.
