Walking before you can run is usually a good idea - for some, walking is all you can or want to do. But don't think that walking is just simply putting one foot in front of the other - cos it isn't, even though really it is! Confused? Read on...
POWER WALKING - No, not lifting weights as you walk - you silly!! Basically it's speed walking. Striding along at a good 5mph is what you want to aim at, takes a bit of practice, though you can achieve it easier on a treadmill as you're in control and once you get going you don't notice the speed. I tend to strap on my iPod and disappear into the shed, jump on Roger and away I go! There are actual mechanics to a speed walk, short fast strides, a strong "toe off" (which sounds rude to me) and a powerful swing to the arms, keeping them close into your body bent at 90 degrees. Thing is, as you go at a faster speed,your body tends to adopt a power walking posture anyway and your arms have to keep up with you. Just be careful you don't whack your hands on your treadmill console as flying off the back inevitably follows.
HIKING - a pre/post lunch amble in the park is not a hike - although its walking so I'll let you off. Hiking is more about were you are not how you do it, though you should try to maintain an even effort. Invest in good foot wear, buy or borrow a roomy backpack and chuck in food, water and a map, if you can fit someone in there who can map read too,that will help!!! Wear layers so you can thin them down instead of freezing if you get wet/sweaty. And take tissues as you always end up with a runny nose when you go out hiking, especially if its anywhere near the sea!
