How to improve your impact loading symmetry?
This section highlights how to improve your impact loading using specific exercises. If you want a deeper understanding of what impact loading is and why it matters, you can explore our dedicated article.
Impact loading is largely determined by the strength and coordination of the lower limb muscles (calves, hamstrings, and quadriceps) and how effectively they absorb the shock. Balanced loading and impact absorption between your left and right leg is important to avoid uneven stress on your body and potential injury.
Since running impacts occur within a (very) short time frame (± 20–130 milliseconds), your muscles must activate rapidly. Plyometric (jump) training is one of the most effective ways to develop this quick activation.
Before your body can handle the demands of plyometric training, it’s essential to first build a foundation of strength. Stronger muscles, tendons, and bones not only prepare you for explosive work but also improve resilience against the repetitive load of running. Additional focus on single-leg strength during this phase also ensures both sides of your body develop evenly.
As you develop this foundation, plyometric training should progress from low-intensity to higher-intensity jumps. This gradual approach ensures safety while maximizing adaptation. The combination of strength training and plyometric drills equips you to be stronger, more resilient, and more efficient at handling the impact forces of running.
Training plan for impact loading
Here we provide a training plan divided into three phases, designed to help you transition smoothly from strength work to more plyometric-based training. Each phase includes three levels of example exercises that can be integrated into your program. Throughout all three phases, integrating single-leg variations helps you build symmetrical impact tolerance so that both legs can share the load efficiently with every stride.
- Goal phase 1: Prepare the body for heavier loading.
- Focus: General (single-leg) strength work combined with light-loaded plyometrics.
