It’s great when people decide to start going to the gym, but there are several problems that new gym members could face regarding injuries.

If not properly trained or stretched, a person may end up with a dangerous workout and some serious injuries.

In an article on Painmed.com, the Centers for Disease Control and Prevention (CDC) stated that 28% of people suffer from low back pain, 19% have knee pain, 15% experience pain in their neck, and 9% have shoulder pain.

Additionally, about 25,000 Americans suffer from ankle sprains every day. That’s 34% of the population dealing with ankle pain each year. However, many of these injuries can be prevented with proper training.

New gym members who jump right into expert-level workouts are far more likely to get injured while working out.

On Mic.com, Hollis Molloy, a CrossFit gym owner, told The Huffington Post that it’s better for new members to “do about 50% of what the rest of the class does.”

It’s very dangerous for beginners to exceed their physical limitations early on. Incorrectly warming up muscles and not knowing the correct techniques and movements for some workouts can rapidly increase the risk of injury.

Just being knowledgeable on the workouts isn’t enough, though. Beginners who do not take care of their bodies, in all aspects, are much more susceptible to injury.

Neuromuscular therapist Maurizio Caveletti says that along with incorrect exercises and bad form, poor sleeping habits can increase the chance of injury. For example, simply sleeping on your stomach can lead to more shoulder pain.

“When you sleep on your stomach, you are putting your shoulder in a constant state of impingement,” Caveletti noted in an article on Frontiersmedia.com.

Experts note that focusing on the importance of stretching, knowing proper techniques, and taking care of one’s body inside and outside of the gym is essential for a beginner to remain healthy.
