Some of the Denver Nuggets aren’t taking the offseason lightly, quite literally. Recent photos posted on Twitter by the team show numerous players working out with assistant coach/strength and conditioning Steve Hess at Red Rocks.

Erick Green and Gary Harris can be seen in the photos running the stairs at the famed amphitheater, wearing what appear to be weight vests.

There are a number of other Nuggets visible in the background, though they are not distinguishable in the photos.

From what we can tell by the photos, Ty Lawson and Kenneth Faried did not appear to be in attendance.
