Beginner 1 Mile Walk | Walk at Home

Walking is also one of the best exercises for losing weight — it’s relatively easy to do, easy on the joints, it’s free and you have to do it every day anyway. 
To start walking for fitness, try to begin with a 20-minute walk every day. “If that’s too much, start smaller,” Dr. Roizen says. “But do set a goal of building to 30 minutes a day, every day.”
Once you’ve mastered that, take your time increasing to a higher level. Never increase more than 10% more any one day than your maximum the prior week. 
When you’re ready, increase your goal to 10,000 steps a day (a pedometer will help — see item #4).
