See Calorie Expenditure Calculator. >Review of the scientific literature suggests that moderately intense aerobic activity needs to be performed most days of the week to bring about significant fat loss. Some sources recommend brisk walking progressing to 45 minutes or more daily. Other authorities recommend working up to 60-90 minutes of daily physical activity for weight loss. >The USDA recommends at least 60 to 90 minutes of daily moderately intense physical activity while not exceeding caloric intake requirements to sustain weight loss in adulthood. About 60 minutes a day may be needed to prevent weight gain. (USDA 2005). >Alternating weight bearing with non-weight bearing exercises every other day may be recommended to minimize the repetitive orthopedic stresses of exercising daily. See Overtraining. The combination of aerobic and anaerobic exercise may utilize more fat than either type of exercise alone. See Fat Loss. http://exrx.net/WeightTraining/Myths.html >Contrary to what the infomercials suggest there is no such thing as spot reduction. Fat is lost throughout the body in a pattern dependent upon genetics, sex (hormones), and age. Overall body fat must be reduced to lose fat in any particular area. Although fat is lost or gained throughout the body it seems the first area to get fat, or the last area to become lean, is the midsection (in men and some women, especially after menopause) and hips and thighs (in women and few men). Sit-ups, crunches, leg-hip raises, leg raises, hip adduction, hip abduction, etc. will only exercise the muscles under the fat.
