Healthy Life Program

ok so im 14 and i do kendo, weight training, and track. apparently, according to my doctor ive been exercising my body too much to the point where my joints are getting messed up, my muscles cramp up frequently, and am tired all the time. also, he says my back is real bad because of stress and that i am overstressed. so my doctor says i cant do activities like running, any kind of weight training, of anything with snappy movements or straining joints for several weeks. so if someone can advise me with any exercise that i can do even while waiting for my body to recover that would be great. any tips will work. thank you.
