The Hidden Muscles: Why We Need to Focus on Our Posterior Chain The posterior chain, comprising muscles along the lower back, glutes, hamstrings, and calves, plays a crucial role in our overall stability, mobility, and athletic performance.

Runners have found that strengthening their hamstrings – typically the most neglected muscle group in running – can significantly reduce niggles and improve performance.
