Rob Gronkowski -- I'M JACKED CENTRAL, BABY!

GRONK STRONG!!!!

GRONK CAN DO 69 PUSH UPS!!!

GRONK PUMPED ABOUT "ENTOURAGE" CAMEO!

GRONK IN "BEAST MODE ... JACKED CENTRAL!"

That pretty much sums up our encounter with New England Patriots tight end Rob Gronkowski, who was out hiking in L.A. on Thursday after shooting his guest role for the "Entourage" movie.

Gronk appears to be crushing it in his recovery from ACL surgery -- and by the way he was throwing the football around, it seems his elbow is in good shape as well.
