Start walking for fitness/health, begin with a 20 minute walk every day. If that’s too much, start smaller like 10 minutes. Set a goal of building to 30 minutes every day. A 12-week study of significantly overweight women, those who walked for 30 minutes, 5 days a week, lost weight at a rate similar to women who walked twice as long, 5 days a wk. Once you’ve built up strength & stamina, increase your pace & lengthen your walks to 60 minutes for even greater cardiovascular/overall health benefits.
