Yes, it’s true – stronger tendons make a stronger body. Tendons, and their helpful cousins retinaculae, are specialized fascia that reinforce the body’s biotensegrity structure in areas where a lot of movement occurs. They can make or break the quality of our movement choices.
According to traditional anatomy and fitness culture, strength is increasing the size of a few big muscles that we can see in the mirror. But bigger is not better.
Doing isolated exercises, like bicep curls, causes the belly or center of the muscle to get bigger. But the tendons at the ends of the muscles are not involved.
