The one on the right (as I look at the screen).
I downloaded both and up-sized each.
My reasons for my choice are because, in the image on the right:
> there's more definition in his Chest and Abdomen.
> the rim light on his L Upper Arm and his R Side creates a better sense of DEPTH (3 dimensionality).

I had a play with a bit of DODGING on his chest and abdomen - I think that it might be worthwhile for you to selectively lighten some areas - that will add a tad more depth (and subsequent general 'strength') to the Image. (And I reset the Black Point, to kill more of the Background).
Here is a rough (my redo is on the right):
The changes are in some areas subtle, I hope they are visible to you.
I think I went too far with the burning of the L. Breast area, but I think his gut generally and especially his R. Side are better defined in the redo - anyway, all for you consideration, it's your call ultimately.
Nice Body. Good Shot - well timed.
The rim lighting really works, I am glad you pursued that direction, not because it was I who initially commented on it, but because I believe that it really works for this type of Subject - AND - it is a real effort in Planning the Camera Viewpoint and Anticipating the Movement to get a decent shot - and when you do, it is so much more rewarding.
