Im afraid that Im experiancing a small back problem. Today when I changed a tire on the car, it was aching like crazy. I had to rest a couple times. Im not sure if its from deadlifting yesterday or what but it is annoying. It doesnt hurt when I stand up or anything, but if I bend over alot, or after some deadlifts it sucks. Would hyper extensions, deadlifts, and some stretching make the lowerback area stronger therefore lower my back pain in the future?
