Bledisloe Cup 2018: Wallabies flanker David Pocock juggles while balancing on Swiss ball

Australian rugby star David Pocock showed off his core strength as he worked out in the gym on Wednesday — by juggling as he balanced on a Swiss ball.

Pocock was filmed by team-mate Adam Coleman, who posted the impressive video on Instagram.

The Wallabies kicked off their Rugby Championship campaign on Saturday but were humbled by the All Blacks as they lost 38-13.

Pocock, who faced New Zealand in that defeat last Saturday, has been working on his stabillity and co-ordination this week as he and his Australian team-mates look to bounce back this weekend.

The flanker juggled three tennis balls while balancing on a blue Swiss ball in his socks as he rocked around but managed to stay standing.
