Germany is perhaps the holy grail of throwing events when it comes to strength and technical aspects.
Below are some devices that I have found that are specifically tailored towards throwing events.
From memory I remember seeing a discus device years ago, but am unable to find it.
EDIT: 1 Year later – Found it! Discus Orbit Machine
If you know of any other strength training devices tailored specifically for the throwing events please let me know and I will include them in this article!
Javelin
Video Caption:
Made specifically for 2013 World Champion Christina Obergfoll the Kraft Training Gerät (German for Strength Training Device) allows athletes to throw along an ideal trajectory with little risk of injury.
The device sled weighs 3.8k and can be loaded with as much as 10k for a maximum weight of 13.8k. This allows athletes to develop throwing strength that is very javelin specific.
Sled is thrown for maximum velocity which is measured between two preset points and is printed in milliseconds after each throw.
Shot Put
Below is a video of David Storl using a shot put specific strength training device.
