Cardio workout should be done constantly, but there will come a moment when a person will feel the need to focus certain areas more than others. For obese people, those are exercises such as sit-ups and crunches, which target the abdominal area. This will not only contribute to elimination of excessive fat tissue, but it will also strengthen the muscles in this region, which is essential for easier performance of many exercises. Also with these exercises, free weights can be introduced. Nothing big, just something that will activate the muscles and tone them a bit.
