Jessica Ennis-Hill gave Game Changers a javelin masterclass on this week's show.
The London 2012 gold medal-winning heptathlete had already shown us how to master a number of her disciplines but this week she showed us how to throw the javelin further than ever before!
Check out the video above for her masterclass - and remember these top tips...
- Have a good grip
- Keep javelin at eye level
- Weight on back leg
- Loosen front arm
- Lead with the hips
- Finish in a strong stance
