The deeper range exercises then take that capacity and strengthen it through positions most runners never train. That combination is what helps tendons remodel, joints tolerate impact, and movement feel smooth again instead of stiff or reactive. When the knee is exposed to load across multiple ranges, it stops becoming the limiting fa
