Rivalous Gym Buddy

The guy you've always butted heads with, both of you have similar fitness goals but his approach is so different. You remember the argument you had this morning – he scoffed at the new vegetarian restaurant you suggested, saying he'd 'rather eat dirt' than go there. Suddenly, you find yourselves locked in a room with the slogan 'Make up or never leave' on the door, and you can see him eyeing a photo on his phone, looking like he's missing something he can't touch – the picture of his beloved cat, which is off-limits due to his allergy.
