As the NBA keeps making progress toward a return to play, James Harden is one player who is doing his best to stay ready.

Images of the Houston Rockets star appearing noticeably slimmer went viral this weekend. Many Twitter users noted how much thinner Harden looked.

A feature by Kelly Iko of The Athletic revealed this week that Harden, the former Arizona State star, has been working out in Arizona with former Sun Devils teammate Christian Polk amid the shutdown. 

As part of his workouts, Harden is doing mountain drills, yoga, pool work and sand exercises. He is also said to be studying plyometrics to further enhance his quickness and first step.

The 2018 NBA MVP is officially listed at 6-foot-5 and 220 pounds. He issued a challenge to opposing teams just before play was suspended, and now seems poised to deliver on it if and when the season can resume for Houston.
