If you've ever wondered why elite runners look so effortless – like they're bouncing lightly off the ground with every stride – plyometrics training is a big part of the answer.
Plyometrics has become one of the most evidence-backed tools in a runner's routine. Whether you're chasing a 5K PR or building up to your first marathon, adding plyometric movements into your week can meaningfully improve your running economy, speed, and resilience.
This guide covers exactly what plyometrics is, why it works, which exercises to start with, and how to safely weave it into your Runna training plan.
What Is Plyometric Training?
Picture a pogo stick. When it hits the ground, it compresses – storing energy – then springs straight back up, releasing all that energy in one explosive bounce. Your legs work in almost exactly the same way when you run.
Plyometric training (or plyos for short) is simply jump-based exercise – think hops, skips, bounds, and box jumps. These work the stretch-shortening cycle (SSC) of the muscle fibers. It sounds straightforward, but the magic happening inside your muscles and tendons is really important:
Here's what's actually going on: Every time your foot hits the ground, your muscles and tendons stretch and load up like a coiled spring. A fraction of a second later, they snap back and propel you forward into your next stride. The faster and more efficiently your body can do this, the less energy you burn at any given pace.
Runners call this running economy, and it's one of the biggest differences between feeling effortless and efficient vs grinding out every kilometre.
Benefits of Plyometrics for Runners
Improved Running Economy
This effectively means you can run faster without working any harder. Think of the springs we described earlier – plyometrics makes them stiffer, snappier, and more efficient.
When will I feel a difference? Over 6–10 weeks of training, you might notice improved efficiency as hitting a pace that used to feel tough and thinking "this feels easier than it should", or cruising at your usual effort but clocking a slightly faster split.
This effect is distinct from aerobic and anaerobic gains and comes primarily from tendon stiffness adaptations and neuromuscular efficiency.
More Power and Speed for Your Finish Kick
You know that feeling in the final stretch of a race – legs heavy, lungs burning – when someone comes flying past you like they've been saving a secret gear? Plyometrics helps you be that runner.
Here's why: a powerful finish kick comes down to how explosively your muscles can push off the ground in that fraction of a second of contact. Plyometrics dramatically improve rate of force development (RFD) – how quickly your muscles can generate force from the ground. For runners, this translates directly to a more powerful push-off and the ability to accelerate when it matters most: the final 800m of a race.
Injury Prevention: Improved Tissue Resilience, Bone Density
Plyometric training, when progressed correctly, strengthens the tendons, ligaments, and muscles in your lower limbs – the exact structures most at risk when you start running more miles.
Think of it like this: every hop, bound, and jump is a small controlled stress on your body, the kind it can handle and adapt to. Over time, your tendons get tougher, your bones get denser, and your legs get better at absorbing the impact of each stride.
In practical terms, that means:
Greater Achilles and patellar tendon stiffness, reducing injury susceptibility as your ankles and knees are less vulnerable – stronger tendons mean the structures around your joints can better handle the demands of high mileage.
Safer landings with every stride as your legs learn to spread the load more evenly, rather than dumping it all into one spot.
Better balance when things get uneven, crucial for trail runners or anyone who's ever rolled an ankle on a pothole.
Stronger bones as the impact forces from plyometrics stimulate bone density in a way that steady-state running simply doesn't.
This is especially worth knowing if you've had a previous lower-limb injury. Research consistently shows that strength training programmes, which include plyometrics, significantly reduce re-injury rates compared to standard training alone.
Improved Balance
It sounds basic, but for runners, every single footfall is a brief, single-leg balancing act. When you're fresh, your body handles this without thinking. But when you're tired – think mile 20+ of a marathon, the back end of a hard interval session, or a technical trail descent – that balance starts to become more challenging.
Your form can break down and your muscles can compensate in unhelpful ways.
Plyometrics trains your body to stay stable and controlled under fatigue and pressure, because that's exactly what single-leg hops and bounds demand.
Better Neuromuscular Coordination
Plyometrics trains your nervous system to fire muscles faster and more precisely – reducing wasted motion, improving your cadence, and making each stride more economical without conscious effort. The result is a stride that feels more fluid, coordinated and effortless – less like you're fighting your body, more like everything is working together.
The Best Plyometric Exercises for Runners
Start with these fundamental movements, progressing from bilateral (two-leg) to unilateral (single-leg) exercises as your strength and confidence grow. For exercises involving a step, you can gradually increase the height of the step to continue improving.
Technique is important when it comes to plyos. Your main goal is to make contact with the ground lightly and minimise your contact – leave the ground quickly! If your movement focuses on landing (e.g. a box jump), then focus on landing with control.
How to Incorporate Plyometrics to Your Runna Training Plan
If you are new to plyos, it is important you introduce them into your training schedule gradually. They are a fairly high impact form of training, so we recommend leaving at least a 6-hour window between your running and plyometric training and avoiding them the day before a key speed or long run session. This is due to the timing of your bone cycles and will reduce your chance of injury.
The good news is that if you're already doing Runna's strength sessions, you're likely already doing plyometric movements. Exercises like jump squats, single-leg hops, and explosive step-ups are all plyometric in nature, and they're built directly into Runna's strength programming. If you haven't set up your strength plan yet, go to Manage Plan and configure your Strength Plan.
Here's how to integrate plyometrics safely:
Frequency
Beginners: 1 session per week
Intermediate/Advanced: 1–2 sessions per week
Progression
Build over 6–8 weeks like this:
Weeks 1–2: Double-leg only, low volume, focus on landing quality
Weeks 3–4: Introduce single-leg work, add horizontal movement
Weeks 5–6: Increase speed/reactivity, add bounding
Weeks 7–8: Introduce drop jumps / more complex movements
Using Plyometrics in Your Warm-Up
A handful of well-chosen movements at the start of a run is another effective and underused ways to incorporate plyos. Try including some light plyometric drills in your dynamic warm up to:
Activate key muscles (glutes, calves, hip flexors) that tend to be sluggish first thing
Reinforce good movement patterns that carry over directly into your running form
Common Mistakes to Avoid
Starting single-leg work too soon – build double-leg strength and stability first
Too much volume, too fast – the tendons and connective tissue adapt more slowly than muscles so keep progress steady
Doing plyometrics when fatigued – technique can break down and injury risk rises
Replacing strength training – plyometrics works best in combination with heavy resistance training, not instead of it
Plyometrics vs. Strength Training: Do You Need Both?
Short answer: yes. They complement each other perfectly.
Strength training builds the muscle force and tissue capacity needed to safely tolerate plyometric loads
Plyometrics trains the elastic energy return
Final Takeaways
The runners who stay healthy and keep improving year after year aren't just the ones who run the most miles. They're the ones who invest in the foundations, strength, mobility, resilience, that allow those miles to keep adding up. Plyometrics is part of that foundation.
