Lamar Odom's hike with Khloe and Kim

Lamar Odom joined Khloe Kardashian and Kim Kardashian West for a hike on Super Bowl Sunday.

The basketball star - who collapsed in a brothel in Nevada last year following an alcohol and drugs binge - recently left hospital to continue his physical rehabilitation at home and has been making steady progress.

On Sunday (07.02.16), he joined his estranged wife Khloe and her sister Kim for a hike before the trio watched the Super Bowl together.

Kim livestreamed the hike, teasing fans with glimpses of Lamar's shadow.

TMZ reports that this is the first time Lamar has been exercising properly since his collapse.

Kim later posted a picture of the surrounding area on Instagram, with a glimpse of what is believed to be Lamar's arm.

She wrote: "Super Soul Sunday time before Super Bowl Sunday time with Khloe & Lamar."

Lamar recently moved into a rented home in the same gated community as Khloe so she can continue to help him with his recovery.

A source said: "He can move around alone, and he can communicate much better. In the beginning, he couldn't talk at all. He knows how much Khloe has been there for him, and he is so grateful. The therapy can be incredibly frustrating and he has hard moments, but Lamar is a former athlete. He's strong. And he really wants to get better.

"Khloe continues to look after him. Khloe visits him at his house and Lamar hangs out at hers."
