Strength training has long been overlooked by runners who often focus solely on logging miles and improving endurance. However, integrating strength training into a runner's routine is essential for enhancing performance, building resilience, and reducing the risk of injuries. This chapter introduces the foundational concepts of strength training specifically tailored for runners, highlighting why it is a vital component of a well-rounded training program.

Runners rely on efficient biomechanics, which depend heavily on strong, balanced muscles. Strength training targets key muscle groups, such as the core, glutes, hamstrings, and calves, which play pivotal roles in running form and power generation. Strengthening these areas not only improves running efficiency but also helps to correct imbalances that may lead to overuse injuries.

In addition to preventing injuries, strength training can significantly boost a runner's speed and endurance. Building stronger muscles allows for greater force production, which translates to a more powerful stride. Moreover, improved muscular endurance means that a runner can maintain optimal form and energy output over longer distances, delaying the onset of fatigue.
