Which structures are strengthened by progressive overload in addition to muscles?

• A. Cartilage only
• B. Ligaments and tendons
• C. Nerves
• D. Hair and skin

Answer: (B)

Progressive overload strengthens not just the muscles but also the tissues that connect and support them. Ligaments and tendons bear the increased forces during training, and with gradually higher loads their collagen fibers adapt by realigning and cross-linking to become tougher and more resistant to strain. This helps joints remain stable and better able to transmit greater force as you get stronger. Cartilage doesn’t respond to overload in the same way and is more limited by its blood supply, so it isn’t strengthened to the same extent. Nerves improve in how efficiently they recruit muscle through neural adaptations, but that’s not a structural strengthening of tissues. So the best answer is ligaments and tendons.
