Walking is one of the best forms of exercise and it doesn’t require any special equipment, just a willingness to get up and go.
If you haven’t walked in awhile, go until you feel the first signs of fatigue and turn around.
Go a bit farther each day afterward. If you can walk just everyday for 30 days, you will have developed a habit of walking.
A pedometer will measure the distance you walk and count the number of steps you take each day. Aim for 100 more tomorrow than you took today until you can regularly take 10,000 steps a day.
