"Yeah, yeah, 'Lee. Take five", the turtle groaned, as he managed to get on one knee. Taking a moment to crack his neck, and rolling his shoulder, Raphael sat down in the grass. 

Even though Charlie was nowhere near as muscular as him, it was all thanks to her newfound workout routine with Jennifer that she was able to gain some upper body strength. As humble as Jennifer was, her sister was making an improvement, beneficial to Charlie's ever-growing athleticism. These routines took hours, from an early morning, all the way to an early evening, along with a few breaks in between. Although it seemed easy, but it was a rather rough journey, but the girls were able to pull it off together, along with a bit of help. 

Weapons were a [i]whole[/i] 'nother matter. While Charlie was prepared for hand-to-hand situations, learning how to defend yourself from a certain weapons were something that didn't quite fit in with the styles that they were currently teaching her...at least, not yet. As a result, Raphael didn't, at all, use his sais in any of his sessions with her. Learning how to defend yourself from such a weapon wasn't easy to come by, it was just as hard as wielding them; anything in the Kobudo category wasn't for beginners, unlike other martial art styles. 

Charlie was a fast-learner. He and the others figured that out, a long time ago. While not exactly experienced, she clearly had great tenacity, as she wanted to take in as much as she could from her sister and the brothers. So far, she proved to be a very capable student. These thoughts circled in the red turtle's mind, putting them to high regard.
