"Change someone's physique?" Ryan still looks a little unsure of himself.
"Yeah," you nod. "I mean, like add muscle, or make someone taller -- that kind of thing." It seems like a long shot, but it's worth trying, you figure.
"Hmmm," he thinks for a moment, before a slight grin appears on his lips. "Well, you said you needed to do crunches, right? Before baseball practice, or basketball, or whatever sport is going on this season."
"Football," you say, trying to withhold any signs of judgement in your voice as you correct him.
"Whatever," he shrugs. "Well, what if you had twenty more pounds of muscle on your frame, and a well-developed six pack? Then you wouldn't have to do any crunches, right?"
Almost as soon as he says it, you feel your chest and arms swell outwards, and your stomach begin to ripple. You lift up your shirt, revealing an impressive set of washboard abs that weren't there a moment ago. To top it off, your shorts have grown slightly tighter as your thigh and leg muscles build out with pound after pound of new muscle.
"Holy frick!" you exclaim, marveling at the results. "It would take me a month straight in the weight room to come anywhere close to this kind of results! I'm probably the most ripped kid on the team now!" Looking back up at Ryan, you see him smile slightly, excited to see that the test worked. "Thanks, Ryan!"
"Don't mention it," he says, his eyes glimmering. "But I've got something even bigger in store!"
"Oh?" you say, tilting your head slightly. "What's that?"
