Last update: 30 May, 2022

CrossFit is a form of high-intensity power fitness that’s become very popular around the world. While its initial goal was to prepare people with physically demanding jobs, nowadays, it’s been adapted to all audiences. Do you know the benefits and risks of CrossFit?

Although this type of training is quite attractive for those who want to lose weight, increase muscle mass, and gain strength, it has some disadvantages people should consider before practicing it. Below, we explain them in detail.

What’s CrossFit?

Before knowing the benefits and risks of CrossFit, it’s important to know what it’s all about.

This is a form of training based on constantly varied exercises with functional movements that are executed at a certain time, which shouldn’t exceed 50 minutes. The activities practiced include cardiovascular exercises, weight lifting, and strength work. It also aims to explore a person’s different skills and physical abilities.

However, it’s necessary to have enough fitness, flexibility, balance, and muscular and respiratory resistance. It also requires proper motion biomechanics, as not doing the exercises properly can lead to spine, joint, and other bodily injuries.

The benefits and risks of CrossFit

Although CrossFit has become popular around the world, its practice is controversial. While many of its benefits have been supported by studies, cases of multiple injuries and serious consequences have led people to believe that it can be dangerous.

The big problem is that many people have decided to practice it without first evaluating their fitness and state of health. Some people have even decided to follow intense workout routines without the supervision of an expert trainer.

Below, we’ll detail these benefits and risks.

The benefits of CrossFit

Contrary to what many people think, CrossFit isn’t an exclusive form of exercise for high-performance athletes. In fact, nowadays, many people practice it around the world.

However, it’s necessary to know how to adapt it to each person’s physical abilities. In this regard, the exercise routine won’t be the same for a person in poor physical condition than for those who exercise regularly or are used to vigorous exercise. Therefore, it’s imperative to consult your doctor and evaluate your physical performance before trying it out.

In light of the above, and respecting the biomechanics of movement of each exercise, CrossFit offers interesting benefits such as:

  • It increases cardiovascular and respiratory endurance.
  • It increases physical endurance.
  • CrossFit enhances coordination and balance.
  • It improves mood and self-esteem.
  • It helps to increase muscle mass.
  • CrossFit helps people lose weight (it’s considered a “fat burner”).
  • It fosters relationships, as it’s often practiced in groups.

The risks of CrossFit

As we mentioned above, CrossFit can be dangerous if you don’t take precautions. If you don’t evaluate your current state of health or do vigorous exercises without having the necessary endurance, you can suffer from:

  • Muscle, ligament, tendon, and bone injuries.
  • Spine injuries.
  • Weakening and prolonged fatigue.
  • Cardiovascular system changes, such as increased blood pressure.
  • Rhabdomyolysis, a condition that involves the breakdown of muscle tissue. As it causes the release of muscle fiber contents in the blood, it can lead to problems such as kidney failure and arrhythmias.
