For those living with hypermobility spectrum disorders (HSD) or Ehlers-Danlos Syndrome (EDS), the advice to "get stronger" is a double-edged sword. While it is widely accepted in clinical circles that building muscle is essential for stabilizing joints that lack natural connective tissue support, the path to achieving that strength is fraught with unique biological challenges.
Research indicates that individuals with hypermobility often generate approximately 30% less muscular force at baseline compared to their non-hypermobile counterparts. Because their bodies lack the structural integrity provided by dense tendons, ligaments, and fascia, they are disproportionately reliant on muscular support. Yet, standard fitness programs—designed for the general population—often lead to fatigue, injury, and systemic pain for this demographic.
To navigate this, experts are increasingly advocating for the "Goldilocks Principle": a tailored approach to strength training that avoids the extremes of over-exertion and under-stimulation.
Main Facts: The Physiology of the Bendy Body
At the core of the hypermobile experience is a fundamental disconnect between the nervous system and the musculoskeletal structure. Connective tissue serves as a sensory organ; when it is lax or overly compliant, the brain receives suboptimal data regarding joint position (proprioception). This leads to a state where the body must work twice as hard to perform basic movements.
Strength training, when approached correctly, addresses this by:
- Improving Proprioceptive Feedback: Through controlled resistance, the brain receives clearer signals about where the limbs are in space.
- Creating Active Stability: By increasing muscle mass, the body creates an "internal brace," compensating for the "loose" external passive structures.
- Regulating Nervous System Tone: Slow, deliberate movement can help modulate the overactive sympathetic nervous system often found in those with dysautonomia.
Chronology: The Evolution of Exercise Protocols
Historically, medical advice for hypermobile patients leaned toward total avoidance of heavy loads to prevent subluxations. However, the last decade has seen a paradigm shift.
- Pre-2015: Conventional wisdom focused on low-impact activities like swimming or gentle yoga. While safe, these often failed to provide the necessary stimulus to increase bone density or muscle power.
- 2015–2020: Emerging pilot studies, such as the feasibility study on "Heavy Shoulder Strengthening" in HSD patients, began to challenge the status quo. Research showed that tissues could adapt to resistance if the load was introduced with extreme precision and gradual progression.
- 2020–Present: The current era emphasizes "neuromuscular control." Experts like Dr. Libby Hinsley have moved the focus away from "exercise as a chore" and toward "exercise as a precision tool," utilizing slow tempos and specific sensory feedback to ensure the target muscles—rather than compensatory stabilizers—are doing the work.
Supporting Data: Why Standard Training Fails
The failure of standard gym programs for the hypermobile population is rooted in three primary areas:
1. The Proprioceptive Gap
Studies have consistently shown that hypermobile individuals suffer from impaired proprioceptive precision. When a standard workout program mandates high-speed repetitions or complex, multi-joint movements, the bendy body struggles to track the joint’s position, leading to micro-trauma or "over-shooting" the safe range of motion.
2. Muscle Recruitment Patterns
A phenomenon frequently observed in clinical practice is "compensatory recruitment." Even when a movement looks correct, the individual may be using secondary muscles (like the traps or neck) to stabilize a joint because the primary movers are under-engaged. This leads to chronic tension headaches and neck pain, even if the person is "working out."
3. Recovery Thresholds
The "bendy body" often requires a longer duration to recover from the metabolic and mechanical stress of exercise. Standard programming that calls for 3–5 days of intense training per week often triggers a "crash"—or a flare-up of symptoms—that can set a patient back by weeks, reinforcing the cycle of sedentary behavior.
Official Responses and Clinical Perspectives
Physical therapists and exercise physiologists specializing in EDS emphasize that the most critical element of any program is individualized agency.
"Strength training is not a monolith," says Dr. Libby Hinsley, a specialist in the field. "It is a highly individual process that must account for daily symptom fluctuations."
Clinical experts argue that the "Goldilocks Principle"—finding the middle ground—is the only sustainable path. If a session is too intense, the nervous system enters a fight-or-flight state, causing a flare. If it is too light, the body never reaches the threshold of adaptation required to build the muscle needed for long-term stability.
Implications: Building a Sustainable Program
To build a program that actually works, one must shift the goalposts from "performance" to "functional control."
The "Just Right" Variables
- Frequency: Start at one day per week. If the body recovers within 48 hours without a symptom flare, consider adding a second day in the following weeks.
- Volume & Intensity: Instead of "3 sets of 10," try "1 set of 3–5." The goal is to finish the set feeling capable of doing more, not exhausted.
- Tempo: Adopt a slow cadence—2 seconds to lift, 4–5 seconds to lower. This forces the brain to remain engaged and prevents the use of momentum to "cheat" the movement.
- Range of Motion: Don’t go to the end of your joint’s range. Stop just before the point of hyper-extension. The goal is to build strength in a "mid-range" that is stable and safe.
- External Feedback: Use mirrors, kinesiology tape, or compression garments to provide the sensory input the brain lacks. If you can’t feel the muscle, you can’t recruit it.
Positioning and Safety
For those with associated conditions like POTS (Postural Orthostatic Tachycardia Syndrome), upright exercise can be dangerous. Shifting to supine (lying down) or seated positions allows for the benefits of strength training without the cardiovascular strain of constant postural changes.
The Path Forward: A Call for Caution and Consistency
The most important takeaway for the hypermobile community is that there is no race.
If you are just beginning, start by performing an "educated guess" on your capacity, and then do half of that. Use the following days to monitor your response. Did you experience a mild, "good" muscle soreness? Or did you experience a multi-day crash?
When to consult a professional:
- If you experience sharp, shooting pain during movement.
- If you have persistent swelling in joints following exercise.
- If your heart rate remains erratic or you feel lightheaded during or after the session.
- If you are unsure how to isolate a specific muscle group.
A hypermobility-informed physical therapist can help design a bespoke program that accounts for your specific sub-type of EDS/HSD, skin fragility, and autonomic nervous system triggers. By respecting the "Goldilocks" boundaries—neither too much nor too little—strength training transforms from a source of anxiety into a powerful tool for autonomy, stability, and long-term quality of life.
Summary Checklist for Beginners
- Preparation: Always perform a gentle, low-resistance warm-up to "wake up" the connection between brain and muscle.
- Engagement: Ask yourself, "Where should I be feeling this?" If you aren’t sure, reduce the weight or the range of motion until the target muscle becomes obvious.
- Record-Keeping: Track your sessions. Note not just the weight lifted, but how your body felt 24 and 48 hours later.
- Patience: Your goal is adaptation, not fatigue. If you finish your workout feeling energized rather than depleted, you are in the "just right" zone.
