Yes, usually exercise is a good idea with arthrogryposis, but it should be personalized. The safest and most useful approach is usually regular stretching, range of motion work, strengthening, balance, walking or gait practice, and function-based movement that helps with real daily tasks. Good activity ideas are often pool or swimming work, walking, treadmill work, bike or adapted bike work, and therapist-guided exercises for the joints and muscles that need the most help. The intensity should usually be gentle to moderate and consistent, not all-out. The goal is to improve movement, strength, and function without pushing into sharp pain, joint strain, or heavy fatigue. In plain terms, it should feel helpful and challenging, not punishing. What works best really depends on the person’s joints, strength, pain level, and goals, so PT or OT guidance matters a lot.
