Looks like the Arnold Schwarzenegger of the Aussie animal kingdom Roger the ‘roo has been keeping himself healthy the past few months.

He first shot to international fame a years ago when his muscular physique caught the world’s attention, and it appears that he hasn’t slacked off when it comes to keeping toned!

New footage from his home at the Kangaroo Sanctuary Alice Springs shows that you don’t want to get on his bad side!
