Final answer:
In resistance training, bones are typically the least likely to be injured due to their design to support load, whereas muscles and tendons are more susceptible to overuse injuries from misuse or inadequate recovery.
Step-by-step explanation:
In resistance training, the least likely site to be injured is typically the one that is exposed to the least amount of stress during the exercise routine. Considering muscle, tendon, and bone, the bones are often the least likely to be injured as they are designed to support the load, provided that the muscles and tendons are functioning correctly. The overuse injuries most commonly associated with resistance training are more likely to occur in muscles and tendons due to improper technique, excessive load, or insufficient recovery time. Muscles can suffer from cellular damage leading to soreness, and tendons can be overworked, but bones are generally more resilient unless subjected to extreme loads or sudden impacts that exceed their structural capacity.
