It's clobbering time!
Of course, when we say "it's clobbering time," we really mean that it's time to get ripped at the gym!
Matty was recently spotted heading home for the afternoon after a tough workout in West Hollywood!
We're not exactly sure what his regimen consists of, but what we do know is that it's doing some pretty amazing things to his arms!
Seriously, look at those guns!
Ch-ch-check out more pics of Matty getting wicked buff (above)!
