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.
Yes, you should keep working out even though you are sore, but there is more to it than that. Muscle soreness has two primary causes. The first soreness you experience happens during your workout (the burn) and should subside within a couple of hours.This is caused by lactic acid production.. You absolutely must rest the muscles you worked for 1-2 days after a workout. Take at least one day off between strength training sessions, and if you are still very sore, take 2 days off.
