Back in February, Rob Kardashian revealed that he'd packed on some pounds since his romance with Rita Ora.

"All I did was waste a lot of money and gain 40 pounds," Rob told his sisters on an episode of "Kourtney & Kim Take Miami." "I need to focus on me. That’s all I wanna be about."

And it looks as if that's just what he's doing. The reality star and sock entrepreneur, 26, went for a hike in Culver City, Calif., Wednesday, while sporting a shorts-and-spandex getup.

Last month, Rob revealed one, er, tiny problem he's faced due to weight gain.

“Every time I hop in the shower and see myself naked I cry,” Rob said during the E! News special “Ryan Seacrest with the Kardashians.” “My penis looks so small now.”

He added, “The upside is, every time you lose 10 pounds you gain an inch on your penis."
