Behind the Stroller? Pushing the Pram?

The one thing I am certain I do properly, is make sure that the baby gets at least one good walk a day. Even if it is cold or raining (I am Canadian, I wait for no weather).

That said, walking and pushing the stroller isn’t get me back into shape. I find this is a bit shocking. When I wore one of those “ten thousand steps a day” pedometers, I found out that I generally take 10,000 steps before 11 a.m.
According to an article in UK’s The Guardian, walking can be a fitness and weight loss program, if you do it properly. Here are some tips I gleaned from the story:

1. Incorporate 10-minute sprints of fast walking into your daily plan
2. To lose weight, you probably need to take at least 16,000 steps per day
3. Climbing hills or walking challenging terrain will increase calories burned
4. Walking on mud, sand or grass burns more calories than walking on pavement
5. Walking on cobblestones or rocky ground may have more benefits. Physiologists at the Oregon Research Institute found that walking on cobblestones — an activity rooted in Eastern medicine — leads to improved blood pressure and physical balance.

Now, all I need is an all-terrain pram with really big wheels…and possibly mud flaps. Anyone care to make a recommendation?
