Many of us boast our exercise accomplishments like badges of merit. But believe it or not, some of the trendiest workout regimens are not worthy. Really. As it so happens, certain activities can do more harm than good. 

The Department of Health and Human Services recommends at least 150 minutes a week of moderate aerobic activity or 75 minutes a week of more hardcore aerobic activity. With these guidelines, it’s important to keep in mind that all exercise is not created equally. 

While it’s better to have an exercise regimen than to be sedentary, working out is not without its own risks. Multiple factors are involved, including your age and fitness level, as well as where and when you are getting physical activity on a regular basis. Also, the type of exercise one does may present its own set of potential problems.

According to the National Electronic Injury Surveillance System, which is overseen by the U.S. Consumer Product Safety Commission, the rate of injuries that occurred as a result of exercise or exercise were up nearly 45 percent between 2007 and 2010. 

Below is a list of some of the most common offenders. Even though exercise enthusiasts may think they’re putting their best foot forward, upon closer look, that isn’t always the case.

Because of their vigorousness, jogging, running and competitive sports are associated with an increased risk of injury, says www.medscape.com. According to a report by FamilyDoctor.org, up to 70 percent of runners are injured annually.

If you are worried about hurting yourself from these activities, slow your roll. Switch to walking, a moderately intense physical activity, which is associated with a very low risk of musculoskeletal complications. Commonly used methods to reduce musculoskeletal injury and complications include warming up and cooling down before and after exercise, stretching, and a gradual progression in the intensity of your workout.
