Avengers actor Jeremy Renner speaks about his recovery from a horrific snowplough accident 

It’s been  three months since he was involved in a catastrophic snowplough accident that left him with over 30 broken bones. Now, Jeremy Renner is back on his feet, taking big steps towards his recovery.

The Avengers actor recently shared a video of himself walking on an anti-gravity treadmill: a special type of treadmill that allows users to walk or run an environment in which a person's body weight is reduced because of the lower gravitational force.

“I now have to find other things to occupy my time so my body can recover from my will,” he says in the video. “I walk using 40% of my weight."

The 52-year-old was rushed to the hospital on 1 January after a snowplough ran over him at his home in Reno, Nevada in the US, after a snow storm.

According to a report by local police, Jeremy used a PistenBully snowplough to rescue his nephew, Auggie, when his car got stuck in the snow near his house.

He managed to tow the car out of the snow, but when he got out, the plough began to move because he'd forgotten to put the emergency brake on.

He was trying to get back into the driver's seat to stop it from moving and running over Auggie but "he was pulled under the PistenBully, and the track rolled over him", the Washoe County police report said.

He suffered critical injuries including a broken torso, blunt chest trauma, and some injuries to his head and face.

He was airlifted from the scene and rushed to hospital for emergency surgery and was discharged after spending weeks in the intensive care unit (ICU).

Auggie later penned a letter to his real-life hero for saving him in the snow storm.   

“I’m very lucky because my uncle is Hawkeye (one of the Avengers),” he wrote. “I’m also very lucky that my uncle is alive from his accident.”

After being discharged from hospital, Jeremy has been recuperating at home with support from his family and friends.

The action star says the crash changed his perspective on things.

"Morning workouts and resolutions all changed this particular New Year’s," he said in an Instagram post.

"Spawned from tragedy for my entire family, and quickly focused into uniting, actionable love.”
