| most overtraining refers to athletes in a high school or collegiate setting. Some of these kids are training year-round for multiple sports (competition, practice, conditioning, weight room). Most who experience this are not giving themselve opitmal time to rest or allow proper progression as their training cycles change. It's an unfortunate thing I've seen happen (and well-documented). Most fitness enhusiasts or recreational athletes worry about this but they are coming nowhere close to the type of volume some of these kids are taking on. For the general fitness population, I say don't even think about overtraining. Just worry about plateauing |
