Walking and running are common aerobic exercises that can reduce diabetes risk. However researchers also found that strength training (weight lifting) or muscle conditioning (stretching, etc) helps too. From a national sample of 99,000 women aged 36-81, they found that at least one hour of strength training and conditioning plus at least 2.5 hours of aerobic exercise per week led to a 67% reduced risk of diabetes.
PositiveTip: Choose a variety of aerobic, strength and conditioning options to your exercise regime.
