How to add miles and speed at lower risk if running after injury

I just got a great question from a runner with a cuboid fracture. He signed up for four weekly coaching calls as he was returning to running. 

He just wanted to make sure that he didn't make the fracture worse as he was actually getting back to activity. 
 
He asked, “Once I start running outside, can I use the Alter-G treadmill to add miles and speed while lowering overall tissue stress?”
 
Can I use the Alter-G treadmill to add miles and speed while lowering overall tissue stress after recovering from an injury? 
 
That's a great question and that's what we're talking about today on the Doc On The Run Podcast.
