Man, if your back is popping your definitely overdoing it. Your only supposed to get really sore when you start working. A little bit sore is normal sometimes after a good workout, but even the trainer I used to talk to (someone who trains junior hockey players, some of the biggest and baddest young adults in amateur sport leagues) that you shouldn't be sore other than your first workout after a long. The most you should feel after a workout is some tense muscles.
NuAki's right you are really overdoing it. You may think yeah its less to worry about tommorow but in truth your probably doing more damage to yourself than actually keeping yourself fit and you might suffer from it in the future. its been proven that if you work out too long the acid (the name escapes me at the moment) that burns off the fat starts to burn off the muscle as well and as such its recomended you only workout for roughly a hour so as not to have such negitive effects.
When i worked out i was told that you should (say if your doing lifting weights) do sets of 30 lifts and by the time you hit 30 you should be struggling so if you hit 20 and you cant lift the weights its to heavy but if you hit 30 and can keep going its to light
... or you could come dig a trench with me at a chemical storage plant, hoping that you don't hit a gas line. I've been working on that for the last two days, as well as digging holes to find said gas and water lines, gluing ten foot PVC pipes together, moving them into the ground, and trying to break concrete with a hammer (because neither the diamond bladed saw nor the trencher could cut through it).
Come on, you know you want to. :D
