CrossFit and injury prevention: advice from an osteopath

Advice from an osteopath to help prevent the most common injuries during CrossFit practice

Created by Greg Glassman and Lauren Jenai in 2001, CrossFit has continued to grow in popularity ever since, with new boxes opening every month around the world.

In Spain, approximately 190,000 practitioners enthusiastically follow the achievements of their national representatives in international competitions. Among the best-known names are Elena Carratalá Sanahuja and Sara Alicia Fernández in the women’s category, as well as Fabian Beneito and Martín Cuervo in the men’s category.

CrossFit is characterized by the repetition and combination of high-intensity movements from different disciplines: weightlifting, gymnastics, running, rowing, swimming and others. Each workout, known as a WOD, or Workout of the Day, is unique and combines different types of physical and technical effort.

Although this training method offers proven benefits for health and athletic performance, it also raises questions about athletes’ physical safety, especially when complex movements are performed at high intensity and with a high number of repetitions.

Injuries and CrossFit: what is the real risk?

With a rate of 3.1 injuries per 1,000 hours of training, CrossFit presents a risk similar to weightlifting, 3.3/1,000 h, gymnastics, 3.1/1,000 h, or running. By comparison, sports such as rugby, 20 to 150/1,000 h, ice hockey, 78.4/1,000 h, or football, up to 35/1,000 h, have considerably higher injury rates.

Contrary to popular belief, beginners are not the ones who get injured the most; experienced athletes are. Once they have mastered the basics, many seek to push their limits: increasing intensity, lifting more weight or attempting more complex movements. The competitive mindset can lead some athletes to exceed their real capacity and increase the risk of injury.

The most common injuries in CrossFit

The most common conditions mainly affect:

Shoulders, 25%: rotator cuff tendinopathy, instability, impingement syndrome.
Back, 14.3%: low back pain, upper and mid-back pain.
Knees, 13.1%: patellofemoral pain syndrome, meniscal injuries.
Elbows: medial or lateral epicondylitis, tennis or golfer’s elbow, ulnar nerve compression.

Most of these injuries are related to overload, overuse or traumatic movements, often worsened by poor technique.

For example, pull-ups and overhead movements place particular stress on the shoulders if they are not performed correctly. In fact, the expression “CrossFitter’s shoulder” is already common in many boxes.

In addition, the risk of injury increases with:

the number of training hours,
participation in competitions,
changes in nutrition,
experience in the practice,
and the presence of previous injuries.

In this context, the coach’s role is essential: they must adapt sessions to each athlete’s level, correct posture and ensure proper supervision throughout training.

Warm-up and recovery: two essential stages

Warm-up plays a crucial role in injury prevention. It prepares the body for the intense effort of the WOD by progressively increasing muscle temperature and mobilizing the joints. A few minutes of gentle cardio, joint mobility and specific muscle activation can significantly reduce the risk of trauma.

In the same way, active recovery — gentle stretching, mobility work, self-massage with a foam roller — supports the elimination of muscular waste products, improves tissue regeneration and reduces the appearance of discomfort and injuries in the long term.

Lifestyle hygiene: the role of sleep and nutrition

Beyond technique, lifestyle hygiene directly influences the appearance of injuries. Lack of sleep alters muscle recovery and increases neuromuscular fatigue, reducing attention and precision during technical movements.

Likewise, an unbalanced diet can delay tissue repair and promote chronic inflammatory processes. An adequate intake of protein, omega-3 and essential micronutrients, such as magnesium and vitamin D, helps support performance and reduce the risk of injury.

In some cases, it is also recommended to consult a sports nutritionist, who can design a personalized nutrition plan according to the athlete’s needs, training intensity and performance goals.

Osteopathic support

Prevention: a key tool

In osteopathy consultations, we often see patients after they have already been injured and have been forced to stop their activity for days or weeks. However, prevention should play a central role.

Why can a perfectly mastered movement, repeated hundreds of times without pain, suddenly become painful? The reasons are multiple: overconfidence, accumulated fatigue, lack of recovery, postural imbalances or poor lifestyle habits.

An osteopath can help to:

relieve muscular and joint tension,
improve mobility,
correct inadequate movement patterns,
and support better recovery between sessions.

Although prevention is a widely accepted concept in osteopathy, solid scientific data supporting it are still lacking. Even so, it can help reduce risks and create better conditions for safe training.

After an injury: recovering mobility and confidence

When an injury occurs, the osteopath works to recover residual mobility and rebalance the mechanical loads that alter movement.

They can also collaborate with other professionals, such as physiotherapists, physical trainers and sports doctors, to ensure a progressive and safe return to training.

An inspiring example: Anthony López Brun-Buisson, osteopath, supported champion Jeff Adler and his coach Caroline Lambray in Canada for eight years, accompanying them all the way to their victory at the 2023 CrossFit Games.

When should you consult an osteopath?

It is not necessary to wait for acute pain before seeing an osteopath. At the first signs of discomfort — persistent stiffness, loss of mobility, unusual muscle fatigue or recurring pain after training — a session can help identify and correct imbalances before they develop into more serious injuries.

For regular CrossFit practitioners, preventive follow-up several times a year helps maintain an efficient body and minimize risks related to the high intensity of this sport.

Conclusion

CrossFit is a demanding discipline that combines intensity, variety and personal challenge. Like any sport, it involves a risk of injury, but this can be significantly reduced through good technical preparation, supervised training, healthy lifestyle habits and regular osteopathic follow-up.

Prevention remains the best strategy for enjoying a safe and sustainable practice.

“CrossFit puts a lot of pressure on the human body. I put my body in vulnerable positions every day.

Osteopathic treatments take pressure off where I need it. In my case: in the lower back and hip. My difficulty bending practically disappeared 100% in just a few treatments.”
