Good news for Calum von Moger ... the star bodybuilder is resting at home and walking without any assistance -- just days after he was in the ICU after reportedly jumping out of a window -- according to a news outlet in Australia.
The Geelong Advertiser is reporting Calum was back at his Mount Duneed home in Australia on Thursday ... where the alleged near-death incident took place.
Remember, von Moger was seriously injured after reportedly crashing through a second-story window earlier this month.
