<p>As a general rule, walking on a treadmill (and really walking in general) should be viewed as offering two benefits;</p>
<p>a) Getting a totally de-conditioned couch potato (like I was) to a level of basic fitness that allows them to begin more intenstive exercise.</p>
<p>b) Later, as an active recovery providing an enjoyable way of moving a little more on alternate days in between more intense workout days. You can’t (or shouldn’t) do the intense stuff (weights, bodyweight circuits, interval cardio) without a rest day in between. Walking, jogging, bike riding, swimming – those are all perfect in between day add-ons as you get more fit and ramp up the number of exercise days.</p>
<p>While I enjoy a nice long walk, from a fat loss or fitness standpoint, there is not much to be gained by stretching your 30 minute walk to a 60 minute walk. I mean, certainly go for it. Walking 60 minutes will burn more calories than walkng for 30 minutes. However, to maximize fat loss and fitness gains, it’s better to think about increasing the intensity of those 30 minutes as you are able, rather than simply slogging away for longer periods of time.</p>
<p>For example, as your fitness allows, start turning that 30 minutes into an “interval” workout. Increase the speed for 30 seconds and then slow it back down for 60 seconds. Or 1 minute and 2 minutes. Or whatever. The details don’t matter much. Better yet, crank the incline up so you are walking uphill and then vary the pace so that the fast bits really hammer you. The idea is to start incorporating short bursts into your workout that get you sweating and panting hard, then ease off to recover. Keep repeating and as your fitness improves, increase the length and intensity of the hard bursts and decrease the length of the rests.</p>
<p>Also, starting to incorporate some body weight and core exercise circuits into your workouts is almost essential for maximizing weight loss and fitness gains. You will progress much faster with less overall time invested than if you just walk (or run or elliptical or whatever) for longer and longer periods. In the early going, an intense 30 minute workout three days a week, along with some lighter walking or whatever a couple more days is probably all you can handle.</p>
<p>My standard walk is under 40 minutes. I’ve never been on the exercise bike for longer than 42 minutes. And I didn’t have my first one hour exercise circuit workout until I had been at it for six months, having lost nearly 50 pounds. My longest workout in the last eight days has been 44 minutes, except for one day when I went for a 5K walk that took me just over 50 minutes. So, don’t feel like you have to slave away for hours on a treadmill.</p>
