4Throws Training Javelin

Odd weights, like 300g or 500g, are excellent for athletes who need to bridge the gap between lighter and heavier implements. They allow you to refine your technique and build specific muscle memory without the physical toll of throwing full-competition weight during every practice session.

No, this is strictly a training tool. While it is designed to WA specifications, it is not IAAF certified, meaning it should be used for practice and technique development rather than sanctioned track and field events.

The moderate flex in the aircraft-grade aluminum helps absorb some of the kinetic energy upon release. This reduces the stress placed on your elbow and shoulder, making it a safer option for high-volume training sessions where repetitive throwing can lead to overuse injuries.

The rubber tip is primarily for indoor use or training on surfaces where you want to minimize damage to the landing area. The steel tip is more durable and provides a more realistic 'stick' in the ground, making it the better choice for outdoor grass or dirt fields.

Yes, aircraft-grade aluminum is chosen specifically for its balance of durability and weight. It is robust enough to withstand the frequent impacts of a high-volume training regimen without bending or warping as easily as cheaper, lower-grade metals.
