A walking exercise program is most definitely a viable way to lose weight (assuming you are following a quality diet). However, here is a great SPIN you can place on the average walking exercise program so that you may get the most of it.
1. Interval Training
It is funny how many people get scared off by the word "training". For some reason it seems to imply strenuous work that nobody really want to put up with. Interval training is NOT the worst thing in the world!
All you do in interval training is add short bursts of hard running into your daily walks. For example, as you are walking, burst in to a run and go for about 15 seconds. Many people believe they can go much longer than 15 seconds when they first do this.
They have MUCH different views after they actually do this! The time you are running is not important, so do not try making intervals longer by easing up on the running. The idea is that after walking for a bit (and being fairly warmed up), you burst into a hard run for a short period of time. Try and go as fast as you can for this short time period.
After about 15 second, ease up and start walking again. Repeat this process a few times as you are walking. The amount of calories you burn just from 45-60 seconds in total of hard running is amazing.
2. Take a Cold Shower
Once you get home from a walk have a shower. When you are finishing up, turn the water to the coldest and rinse under it for 45 seconds. This will put your body in a state of thermogenesis. In other words, your body will begin burning fat in order to create more heat.
This walking exercise program is the ONLY one you need to be successful.
