When it comes to cardio, you'll find that a lot of people skip the treadmill and head straight to the elliptical machine. They think that it gives a better workout, but the truth is that nothing can beat the treadmill in terms of cardio awesomeness! On the elliptical machine, you can't do your sprint training, and even your HIIT workouts aren't as effective. The stride just doesn't feel natural and normal, and you often spend more time wobbling and trying to find your balance than actually working out.

If the weather is cold, the pollution is thick, and allergens hang heavy in the air, it's time to come inside and hit the treadmill. With a treadmill, you can not only change the speed, but you can adjust the incline to make it much harder. Tackle those hills like you would outside, and you'll fit in that epic cardio session.
