Regret
Leonel completely lost himself in a new world. Though he wasn't sure about why he had to do all of these hand exercises just yet, Leonel had already completely forgotten about that curiosity. His mind was entirely focused on the target he had set for himself.
According to his father's training program, flexibility was the very first step to training the fingers of a Force Crafter. Without flexibility as a foundation, everything else would come harder. The flexibility exercises were almost like a mechanic diligently oiling even the smallest components of their machines, building it up so that even the smallest corners were in top working condition.
Only after laying a foundation of flexibility would Leonel turn his attention to strength and speed. Upon reaching this step, Leonel would begin working in dexterity exercises which would teach him how to use his newfound strength and speed.
