Turns out Hector Bellerin isn't just a skinny speed merchant, he's actually a bit of a beast!
We absolutely love a good training montage, from chasing chickens around to running up a mountain and screaming 'DRAGO', we can't get enough.
So when Puma popped up with a training montage to help sell their new sneaks, they decided to call upon those some Arsenal lads to pump some iron.
Now, while we all think of Arsenal players at having fancy footwork and and being a little bit delicate, rather than being super strong and really, REALLY fit. So you'll be pleasantly surprised when you see Olivier Giroud and Hector Bellerin seriously pumping some iron and showing off some impressive biceps.
Despite looking all sorts of skinny and just being super quick, it turns out that Bellerin is actually a bit of a gym hound and certainly impressed us with his grimacing faced pull up.
We reckon Arsenal fans will be hoping all the gym work pays off, as the Gunners kick off their Champions League campaign on Wednesday against Dynamo Zagreb in the Croatia capital.
