Whoa, and we thought Mark Wahlberg had some impressive muscles to show off while in Miami filming his latest movie Pain and Gain!  Clearly Dwayne ‘The Rock’ Johnson has been hitting the gym too!

Dwayne and Mark both star in the film about personal trainers, and while Dwayne is normally quite muscular it looks like he’s been definitely hitting the weights pretty seriously to buff up for this role.

I’m a big fan of muscles, but I think this might be just a bit too much for me.  Very impressive, but I think I prefer men a little less ripped. What do you think?
