Dean was panting hard, his head swirling. At this point, it felt like he was floating on air. "So... Hard," Dean panted. "I-I can't -"

"Shhh, just breathe," Castiel murmured. His breath was controlled and evenly paced.

"I thought you said this was going to be a light jog," Dean huffed. He was dying on the inside and he didn't know if he could make it back to school alive.

"This is a light jog," Castiel said. Dean wondered how the man could run for five miles without breaking a sweat. It was like he wasn't even human. Finally after running for what seemed like an eternity, they reached the pool. Dean collapsed from exhaustion. Sure he worked out, but not to this extent.

"Get up," Castiel ordered, and Dean groaned as he reluctantly obliged. "You complain far too much," Castel huffed. "We aren't even half way done."

"What?" Dean cried. They had just ran a fucking marathon for God's sake.

"You heard me, now get dressed and jump in the pool. Make it fast," Castiel commanded. "And put this on," he said as he tossed Dean some type of swimwear that he grabbed from his bag. Dean examined the suit of a second. It looked like normal tight fitting swim trunks, except there was more fabric on the back.

"A drag suit?" He asked, holding it up, so he could get a better look.

"Yes, and if you put it on in the next five seconds and jump into the pool, it's free." Castiel nodded. Dean ran to the locker room, got changed and quickly slipped his cap and goggles on before diving into the pool. Dean loved the water. It was the only place he felt he could escape his issues and he could just be by himself, with his thoughts. It was like therapy and with each lap he felt more and more relaxed, no matter how rigorous the workout.

By the end of practice, Dean felt like he was about to pass out. His muscles were already feeling sore, and he could barely walk on his trembling legs.

"You clearly would have never been capable of going to JO's if you continued to work out like you have up until today," Castiel signed, tossing Dean his towel. Dean had no energy to talk back, he just sat on the bleachers, towel in hand, panting like an idiot. "You need to lay off any soda from now on and eat more protein and complex carbohydrates. Start eating a lot more meat like chicken and fish. Rice, bread, pasta, and water are now your closest companions. Don't try starving yourself, or giving your food to your little brother. There is nothing you can't eat, except I would suggest to stay away from packaged foods as much as possible. I have written up a list for you of what you should not consume from here on out, if you want to maintain a healthy diet in order to perform well."

"Should I watch my calories too?" Dean asked sarcastically.

"No need. With how much I will be training you, you could eat up to 12,000 calories a day." Dean liked the sound of that. It sounded like a dream come true. Just stuffing his pie hole till he felt like throwing up. Castiel interrupted his train of thought to add that he was going to have to work out five hours every day.

"Wait what? How will I have time for that? I have school, and work, not to mention I have to take care of Sammy," Dean rambled on.

"I am trying to work you to your full potential Dean. This isn't just about JO's. I see potential in you Dean." He affirmed. Dean opened his mouth to say something, but before he could, Castiel continued. "Starting tomorrow you will go to the track at 5 A.M. to do a two hour workout on land. Then after school at 2, you will come back to the pool for a three hour workout in the water. On weekends Practice will be held at 10 A.M. until 3. I'll give you a 3 min break in between on these days until I feel you are capable of going all five hours." This was the worst thing that could have ever happened to him. Dean loved swimming, but this? This was something else. He'd have to push around his schedule, and ask Bobby for more flexible shifts down at the garage. But he supposed it was for a valid reason, and Bobby would understand. He always did.
