Strength training affects which of the following?

Strength training is known to have a comprehensive impact on the body, affecting various tissues, not just muscles or joints. When engaging in strength training, the muscles themselves adapt by increasing in size and strength. However, the benefits extend beyond just muscular development; tendons and ligaments also become stronger as they adapt to handle the increased loads imposed during training.

Additionally, the skeletal system benefits as well, as strength training can enhance bone density and structural integrity. This holistic effect means that all tissues related to movement and support within the body respond positively to strength training, making "all tissues" the most accurate choice. This encompasses not only muscle but also connective tissues, bones, and even the cardiovascular system, as conditioning improves overall fitness and health.
