Does his hug mean something?

So this guy and I go to the same gym, in the past we flirted but nothing really happened. He has a girlfriend now (she doesn't go to the gym); so when I was leaving he came to me, in a playful way, hugged me, lifted me off the ground and walked with me a little; I demand quickly for him to let me go... cause I feel this may be inappropriate or not?
