Lamar Odom has overcome a big milestone, tackling his first completed hike with Khloe and Kim Kardashian by his side.

The sisters live streamed the hike near their Calabasas, California home and without directly revealing the former basketball player on camera, hinted the 36-year-old was on the road to recovery, TMZ reports.

It was reportedly the star's first outdoor exercise since he was found unconscious in a Nevada brothel last year.

"Super Soul Sunday time before Super Bowl Sunday time with Khloe & Lamar," Kim tweeted on Monday (NZ time).

Khloe revealed in an interview on Live With Kelly and Michael in January that the NBA star, who she remains married to after calling off her divorce, is doing well.

"It's such a relief," she said."It was terrifying and scary. No one knew what was going to happen."... he wasn't even walking three weeks ago, and now he's walking."
