[ Wally can't say that visiting the gym is something he does with any sort of regularity himself. It's not that he's adverse to physical exertion, he just has a job that provides him with plenty of exercise to go along with his own hero activities. He also happens to have a metabolism that's faster than most which helps with the whole staying in shape thing.

But, one of the downsides of that metabolism is hunger is always right around the corner, especially after he expends a lot of energy from say working out, which is why his gaze lingers on her bag of snacks a little longer than it should when she pulls out the apple to the point he misses part of what she's saying.

Luckily, he stops mentally kicking himself for not bringing at least a few protein bars with him to catch her asking about his speed and his eyes shift from the bag to meet her own as he sheepishly runs the hand not holding the towel through his slightly damp hair. ]

Well, not always. I think the best way to describe it would be to say there is kinda like an inherent switch I can turn on whenever I want to use my powers.

[ He shrugs, tossing the towel haphazardly in the direction of his own bag lying on the floor near the bench. He doesn't mind discussing his powers and what he can do with them as long as he doesn't have to mention the extra-dimensional energy known as the Speed Force that serves as the source of his abilities. ]

It's a good thing too because otherwise everything would appear to be moving in slow motion all the time and that's not as fun as it might sound.
