Loosening a tight Achilles tendon requires a combination of stretching, strengthening, and proper care. Here's what you can do: 1. Stretching: Perform gentle calf stretches to alleviate tension in the Achilles tendon. Examples include the wall calf stretch and the stair stretch. 2. Foam Rolling: Gently roll a foam roller along your calf muscles to help release tension and increase blood flow. 3. Eccentric Exercises: Consult a physical therapist for guidance on eccentric exercises that specifically target the Achilles tendon. 4. Massage: Consider getting a professional massage to help relax and loosen tight muscles. 5. Footwear: Ensure you wear appropriate footwear that provides proper arch support and cushioning. 6. Rest: Avoid overuse and give your Achilles tendon adequate time to recover between workouts.
