The Ireland squad hit the gym today in Celtic Manor in preparation for their crucial Pool D game against France on Sunday.
Ireland strength and conditioning coach John Kiely explained the type of weight lifting bar that Cian Healy was using in the video.
Hex bar is an unusual shaped bar and it is very useful for a lot of the lads as it allows you to grip the bar differently than a normal straight bar so it adds a bit of variety.
In the video Kiely also explained how it can be very useful to use different types of techniques for certain exercises to focus on aiding a players recovery especially considering that the Italy game was only a few days ago.
It is a tough sport, an attritional sport and using tools like this allows you to modify exercises to spare injured muscle tissues and to more specifically load tissues that you want to load.
