Ehlers-Danlos Syndrome (EDS) is a group of rare genetic disorders that affect collagen production, making connective tissue more fragile. This results in excessively elastic and weak ligaments and tendons, causing joint hypermobility, instability, chronic pain, frequent dislocations, and fatigue. Among the most common types is hypermobile EDS (hEDS), but all forms require special care with physical activity.
The good news is that exercise can be a powerful ally — as long as it’s the right type. Weight training (strength or resistance training) emerges as one of the most recommended interventions, while intense aerobic exercise requires caution due to possible cardiac complications.
Why is weight training essential? Muscles as “secondary support” for ligaments.
In individuals with EDS, the ligaments—responsible for the passive stability of the joints—do not perform their function well due to defective collagen. The muscles then become the primary dynamic stabilizers of the joints.
Strengthening the periarticular muscles (around the joints) provides extra support, reducing the risk of subluxations and dislocations, decreasing mechanical stress on fragile structures, and alleviating chronic pain. Studies and systematic reviews show that therapeutic weight training brings consistent benefits: significant pain reduction, increased muscle strength, and improved joint stability.
The Ehlers-Danlos Society and specialized physical therapists emphasize that strength training improves proprioception (body position awareness), coordination, and daily functional capacity. Unlike excessive stretching (which can worsen instability), controlled strength training rebuilds the body’s natural “muscular belt.”
How to practice safely :
- Always start by consulting a physiotherapist or physical education professional specializing in EDS (Exercise-Related Musculoskeletal Disorders).
- Prioritize stabilization exercises (isometric or eccentric) before heavier loads.
- Use resistance bands, light weights, or body weight, focusing on slow and controlled movements.
- Avoid positions that cause joint hyperextension.
- Progress gradually to avoid flare-ups of pain or injury.
The result? Many patients report less pain, greater confidence in their movements, and increased independence in their daily activities.
The risks of aerobic exercise: pay attention to the heart and dysautonomia.
Although cardiovascular conditioning is important, aerobic exercises (running, intense swimming, strenuous cycling, or any activity that significantly raises the heart rate) require careful evaluation in EDS.
Many people with EDS experience cardiovascular complications:
- Dysautonomia (including Postural Orthostatic Tachycardia Syndrome — POTS), which causes tachycardia, hypotension, dizziness, and exercise intolerance.
- Mitral valve prolapse (common).
- In the vascular type (vEDS), there is extreme fragility of the arteries, with a real risk of aortic dissection or rupture.
Intense aerobic activity rapidly and sustainably increases blood pressure and heart rate, which can overload fragile blood vessels or worsen symptoms of POTS (post-exercise extreme fatigue, palpitations, fainting). There are reports of exercise-induced myocarditis in cases of vEDS, and physical deconditioning (common due to pain and fatigue) makes returning to aerobic exercise even more challenging.
Practical recommendations :
- Opt for low-impact, controlled aerobic exercises: swimming, stationary cycling, elliptical training, or light walking.
- Monitor your heart rate and symptoms (never ignore dizziness or chest pain).
- Undergo a prior cardiological evaluation (echocardiogram, stress test) — especially if there is a family history of vascular complications.
- Prioritize strength training as a foundation; aerobic exercise comes as a complement, always with proper pacing (start small and increase slowly).
Conclusion: Exercise, yes, but intelligent and individualized.
In Ehlers-Danlos Syndrome, weight training is not just “good”—it’s one of the most effective strategies to compensate for ligament fragility, stabilize joints, and improve quality of life. In contrast, intense aerobic exercise can pose unnecessary risks to the cardiovascular system, especially in those with dysautonomia or vascular involvement.
The secret lies in individualization: a program supervised by professionals who understand the SED (physiotherapist, physical education teacher, and cardiologist) makes all the difference. Never start or change an exercise routine without medical guidance.

Take care of yourself consciously. With the right training, it’s possible to live a stronger and more stable life, even with EDS.
