Gill Indoor Throwing Ball; 500G

The Gill Indoor Throwing Ball (500g) is a technique and arm-speed training tool that lets throwers practice discus and javelin mechanics safely indoors. When winter weather or limited space keeps your squad out of the throwing sector, these balls keep athletes developing the rotational and delivery patterns that transfer directly to competition — making them a year-round staple for throws programs.

Key features & specs:

• 500g training ball for building throwing technique and arm speed
• Designed for safe indoor use in gyms, fieldhouses, and practice spaces
• Suitable for rehearsing both discus and javelin technique
• Durable construction with a ribbed surface for a secure, consistent grip
• Colors may vary
• Great for high-volume technical reps without a live implement

Coach's tip: Build indoor throwing circuits with these balls to reinforce release position and arm speed — the ribbed surface gives athletes a repeatable grip so every rep reinforces good habits. Care: Wipe down after use and store indoors at room temperature; inspect the surface periodically and retire any ball that has worn smooth so grip stays reliable.
