To diagnose a problem with the port, try using a different battery and cord for a while. Damaged Power Cord. The power cord is a wire inside a plastic sheath, and the wire can break with or without damage to the sheath. If the power goes on and off as the cord is moved or bent, the wire is likely broken.
You can work out if you're sore. Don't exercise the same muscle groups that are hurting. Do legs one day and exercise your upper body the next. By doing so, you'll still be able to get exercise and allow your lower body to recover and rebuild.
[â]Swhey 0 points1 point2 points 3 years ago (0 children) As others have said, your back should be sore if you work it properly. You have lower back pain, and that could be an issue. Lower your weight and concentrate on your mind-muscle connection at the top of the lift. Really pull the back tight at the top and feel it through your lats/traps.
