You will get a lot more out of the exercises that you perform for weight loss if you will choose exercises that greatly involve your larger muscle groups like your legs, back and chest. Ultimately the exercises that you choose to help with weight loss should help you to burn more calories during your workout and also stimulate more muscle growth from your workout so that you will burn more calories all the time. By performing exercises that use your larger muscle groups you best accomplish these goals because the larger muscles require more fuel during the exercise and will also develop a greater amount of muscle mass from the stimulus of working out than smaller muscle groups like your arms. Unfortunately many people seem to do the exact opposite and spend all their time working the smaller muscle groups like the abdominals which not only will not help any more to get rid of abdominal fat but will actually do less to help than working the larger muscle groups elsewhere because they are such a small muscle group. Your best plan is to perform exercises like squats that focus on large muscle groups like your legs and back and actually work many other muscle groups at the same time including your abdominals. Try incorporating some large muscle group exercises like the squats into your exercise program and you will quickly see a big positive difference in the results you get out of exercising for weight loss.
