John knew he shouldn't have just taken the class down into the weight room. The small class of seniors obviously would have rather played dodge ball in the gym but he was the teacher after all. For a second he started to worry about the transformation he'd just done. One of the guys couldn't keep their eyes off his massive muscles. He shrugged it off realizing he just liked looking. And once John was able to see his full figure in the mirror he couldn't really be upset.
The high school gym teacher easier filled out the XXL shirt the school had provided him. He posed a little more for himself checking out all his muscle. A couple of the guys laughed. John turned around and realized what he was doing. "Anyway... We'll be in here for today. I want you guys doing proper rotations."
It didn't take long before the students paired up with their friends. Each small group shuffled to a different part of the gym and started working out. John walked over to the dumbbells to try them out. Normally he could lift the forty pounds pretty well. It was heavy but it gave him a good work out. Leaning over the dumbbells he picks it up. "Shit!" he scares himself as the forty pound weight comes hurtling at him. The students look at him and when they realize he's not hurt start to laugh a little. It's a good thing for John only his pride was hurt a little.
His focus changed back to the weights in his hand. They were definitely 40 pounds but they felt so much lighter. He pumped out a few reps and barely felt anything. "Wow..." he grinned. Being able to do that shot his pride right back up. He set the weight back down and went to a heavier one. 50 pounds felt almost as light. There was a little more strain but it wasn't enough for a good workout. He went up to 60. It was better but after two sets already he felt like he could probably do a lot more. He couldn't get over just how big he was. Solid muscle all over his body. He gave his bicep a squeeze feeling the dense strength packed in it.
For a second he almost forgot that he had a class to run. Scanning the room he watched as most of the guys were working out normally. His athletes were dutifully going through a workout while egging each other to lift more. There were a couple of guys just sitting on the stationary bikes watching the TV. But then he noticed one of the one of the smaller guys off in a corner with someone known for being a bit of a bully.
