Some people think that a weight belt will help them with their workout. While a weight belt helps keep your back and abdominals in line, if you continue to workout with the belt, you will actually weaken these areas. These areas will lose some of the workout that you deliver, so you should try to avoid the belt.
Vary your daily strength training routine to let muscles rest. Strength training puts stress on muscles and can cause painful muscle tears and other injuries. By rotating your strength training exercises and focusing on different group of muscles each day, you will avoid injury to your muscles while achieving full body results.
Test your abdominal strength. Start in a sitting position, as if you were finishing a crunch, and lower yourself to the floor. The slower you go, the better you are doing with control. If you feel that you are going to give out and end up falling back quickly you need to do a bit more work.
