In the latest episode of 'Unseen Hours,' we get to watch a few of NBA trainer Drew Hanlen's clients -- rising stars Kelly Oubre, Jayson Tatum and Jordan Clarkson -- go 1-on-1 against each other and a workout with new Chicago Bull Zach LaVine, who seems to be recovering well from his season-ending ACL tear.

You can see more of Drew with Kelly and Jordan in previous episodes of the online series by Pure Sweat Basketball.
