Charlie looked to gem than at the gym rubbing back of his head unsure of how he should start.. he decides to just walk over to some dumbbells and took a simple 20 weight one and starts working out. going bit slow but steady to insure best work out. after a bit would switch hands, as he worked out every now and again he'd get an exp alert, gaining very minor to 5 or 10 exp every few moments, not close to enough to help him level. though after a while he would get an alert saying his Str stat has been increased by one. when he'd stare at the message for a few seconds before starting to grin.. if he simply practiced what is required for the stat he could increase it by 'grinding' so to speak without having to use a stat point. though chances are it'll take longer and longer by doing the same thing over and over, so he'd have to change up as he gets better with each of his stats.
