Bad or Good?
Hmmm, I have never seen weighted clothing before or have heard of anyone using it. However, maybe you may have noticed, maybe not, sometimes joggers and walkers in particular will be wearing ankles weights which will improve your strength quickly. I do not know if these rules apply with your highschool or not, but wearing backpacks is good. If you carry around some of your heavier books up stairs and through halls, you will most definately feel a change in the weight. It will feel as if it is lighter. This is what happened to me. If you look at my lower back specifically, you will notice a very drastic change in my lower backs muscles size. I found this very startling just because they become enlarged so fast. My highschool is huge and has 2 floors so I am up and down them continuously. Therefore, I do not think you would be wearing that vest of yours as long. It's definately worth one hell of a shot. Who knows, you may even develop a new workout system. However, I think it may cause some severe long term effects if you plan to wear it four years. All the continous external weight on your legs and spine. It may cause damage. But I am no doctor so I can not give you a complete answer and this is only my opinion.
