Treadmill workouts are by far the most popular workouts done in gyms and home every day. While they may help you to burn some excess calories and lose some fat, they come at the expense of some pretty significant negatives. In this video, I show you the number one problem with relying heavily on treadmill workouts to get in shape.

Treadmills are not able to mimic the muscular demands of running outdoors because of the activity of the belt. The motorized belt passively takes your hips into extension, nullifying the need for the glutes and hamstring muscles to do that work for you. When you run outside, your body has to use both the hamstrings and glutes to propel your body through stance phase to initiate the next swing of the leg to move your body forward.

If you spend the majority of your cardio workouts running on a treadmill, you will no doubt have an underdeveloped posterior chain (namely the glutes and hamstring muscles) that will cause imbalances in your function when you go do other exercises that require balanced strength in your legs.

It is not uncommon for people that run on the treadmill and do mostly treadmill workouts to see more hamstring strains and injuries than those that run mostly outside. In comparing running on a treadmill vs running outside, this is actually just one of the major differences. I did a complete video covering two others that are just as important.
