A combination of weight training and aerobic exercise might be the best prescription for overweight people at risk for diabetes and heart disease.
Researchers randomly assigned nearly 200 overweight sedentary adults to three different exercise programs.
One group did resistance training, a second group did aerobic training, a and a third group did both.
On average the weight training group gained a pounded and a half and increased their waistlines without changing any heart or diabetes risk factors.
The aerobic group lost an average of three pounds and dropped a half inch off their waists.
The combination group dropped four pounds and an inch off their waists and also saw a decrease in the lower number of their blood pressure -- which is a mark for heart and diabetes risk factors.
Findings appear in the 'American Journal of Cardiology.'
