It's available to every one; You don't need to be in the shape of athletes that are training for the Olympics.
You can be overweight, underweight, obese, thinese, tall, small, men, women, elders, not so elders, almost everyone, all you have to do is get off the couch, move one foot forward, then the next one and repeat as long as you can. I found it easier to do with a mantra, so if you see my lips moving I might be repeating: “Left, Right, Left, Right, Left, Right...”
You can practice your activity almost every where. Tomorrow I'll post about some suggestions.
You don't need to spend a fortune in equipment. But I would highly recommended getting a good pair of comfortable running shoes. I buy a lot of stuff at Walmart but not that. As a bonus, you can get an activity tracker (I don't walk without mine) and a MP3 player for the time when you get sick of repeating your mantra.
Neither Rain, Nor Snow, Nor Sleet, Nor Hail Shall Keep you from enjoying walking.
Talking about walking, look at last week winner of the Vivofit challenge and the runner up.
I can't even imagine myself ever going over 160,000. The winner 201,978 steps and the second one 161,715. Those are very serious people. But really how does a human do that in a week? Yes I end up seventh, there was 10 persons in this challenge so I won't brag much LOL
