Plyometrics — training that involves rapid, explosive movements (jumping, bounding, medicine ball throws) — are often viewed as training only for athletes. In reality, they're valuable for building power and maintaining athleticism across the lifespan. Power declines with age and is a predictor of mortality and disability; plyometric training helps maintain it.

What Plyometrics Train

Power is the ability to produce force quickly. It's distinct from strength (maximum force production) and from aerobic endurance. Power is trained through rapid, explosive movements against resistance.

Plyometrics train the nervous system to recruit muscle fibers quickly and powerfully, and they train the muscles to generate rapid force production. Unlike strength training (which trains maximum force at any speed), plyometrics train force production at speed, which is more relevant to real-world movement.

Power matters for everything from jumping and running to stepping up stairs, recovery from a stumble, and maintaining athleticism with age. It declines roughly 3% per year after age 30 in sedentary individuals but is partially preservable with training.

The Research Evidence

Studies on plyometric training show:

  • Power gains: Plyometric training improves vertical jump, horizontal jump, and rate of force development (how quickly muscles produce force). Improvements are larger than strength training alone for power development.

  • Strength improvements: Plyometrics also improve maximum strength, though not as much as dedicated strength training. The strength improvement is likely because power training recruits high-threshold motor units.

  • Running speed: Plyometric training improves sprint speed and running economy, even in non-athletes. Improvements of 3–5% in vertical jump and 2–4% in running speed are typical.

  • Fall prevention: In older adults, plyometric training (modified to lower-impact versions) improves balance, leg strength, and reduces fall risk similar to balance training alone. The added power component provides additional benefit.

  • Bone density: Plyometrics create high ground reaction forces that stimulate bone-building. Research shows plyometric training improves bone density, particularly in the lower body.

  • Joint stress: Plyometrics create high impact forces. In individuals with healthy joints trained progressively, this doesn't increase injury risk. In individuals with joint issues, it can exacerbate symptoms.

Practical Plyometric Exercises

Beginner/low-impact:

  • Double-leg box step-down (step down from a 12–18 inch box, controlled landing)
  • Bilateral jump-down (jump down from a low step, land softly, pause 1 second)
  • Double-leg hops in place (small rapid hops, 10–15 per set)
  • Medicine ball chest passes (catch and throw a light medicine ball against a wall or to a partner)

Intermediate:

  • Single-leg hops in place (10–15 per leg)
  • Lateral bounds (hop sideways, alternating legs)
  • Box jumps (jump onto a box, land softly)
  • Depth jumps (step off a low box, land softly, immediately jump as high as possible)

Advanced:

  • Single-leg box jumps
  • Bounding (repeated single-leg hops, covering distance)
  • Triple jump (3 consecutive single-leg hops on one leg, then switch)

Medicine ball plyometrics:

  • Rotational throws (hold medicine ball, rotate and throw against wall)
  • Overhead throws (throw ball downward from overhead)
  • Lateral throws (throw sideways against wall from standing position)

Programming Plyometric Training

Plyometrics are intense and require significant recovery. Most programs include them 1–2 times per week, not more.

Beginner plyometric program (1× per week):

  • 5-minute warm-up (easy jogging, dynamic stretches)
  • 3 sets of 8–10 box step-downs
  • 3 sets of 10 bilateral hops in place
  • 3 sets of 8 medicine ball chest passes
  • 2–3 minutes rest between sets
  • 5-minute cool-down

Intermediate program (2× per week):

  • Session 1: Lower-body power

- 5 sets of 5 box jumps (landing softly, rest 2–3 minutes) - 3 sets of 8 single-leg hops per leg - 3 sets of 10 lateral bounds - Rest 2–3 minutes between sets

  • Session 2: Upper-body + rotational power

- Medicine ball rotational throws: 3 sets of 8 per side - Medicine ball overhead throws: 3 sets of 8 - Medicine ball chest passes: 3 sets of 10

Integration with strength training: Do plyometrics on days separate from heavy strength training. The neuromuscular demand is high and overlaps with strength training demand. Example weekly structure:

  • Monday: Strength training (squats, deadlifts)
  • Tuesday: Plyometric training (jumps, bounds)
  • Wednesday: Strength training (presses, rows)
  • Thursday: Easy aerobic + mobility
  • Friday: Plyometric training (medicine ball, jumping)
  • Saturday-Sunday: Rest or easy movement

Progression and Safety

Start conservatively: Begin with low-impact plyometrics (step-downs, light medicine ball work) and progress slowly. The impact forces from plyometrics are high, and rapid progression increases injury risk.

Land softly: Plyometric training requires landing technique. Emphasize landing with soft knees, controlled deceleration, and proper alignment. Poor landing mechanics negate the benefit and increase injury risk.

Adequate rest: 2–3 minutes rest between sets of intense plyometrics. The nervous system fatigues quickly and needs recovery.

Progression timeline: Spend 2–3 weeks on beginner variations before progressing to intermediate. Spend 2–4 weeks on intermediate before advancing.

Joint health: If you have knee, ankle, or hip pain, start with very low-impact options (light medicine ball work) or skip plyometrics and use strength training with explosive concentrics (fast lifting, controlled eccentric).

Plyometrics for Older Adults

Plyometrics are safe and effective for older adults when progressed conservatively. Modified versions work well:

  • Step-downs from low boxes (8–12 inches): Improves power while managing impact
  • Soft landing practice: Step off a small height (6 inches), land softly, pause
  • Light medicine ball work: Catches and throws with 2–4 lb medicine balls
  • Double-leg hops: Small amplitude, controlled landings
  • Walking with rapid arm swings: Combines movement with power element

Frequency should be 1 time per week initially, progressing to 2 times per week if tolerated. Recovery is slower, so adequate rest between sessions is essential.

Special Considerations

Tendon stress: Plyometrics stress tendons significantly. Individuals with tendon issues (Achilles tendonitis, patellar tendonitis) should be conservative, starting with very low-impact work and progressing slowly.

Coordination and proprioception: Plyometrics require coordination. People with poor balance or proprioceptive issues should work with a coach initially to ensure proper movement patterns.

Fatigue effects: Plyometrics are neurologically demanding. They shouldn't be done when fatigued (at the end of a long training session) or when systemic fatigue is high. Do them fresh, early in training.

Footwear: Use cushioned shoes with good support. Plyometrics on hard surfaces with minimal cushioning increase injury risk.

Power is a valuable fitness quality that predicts athletic performance, fall prevention, and long-term health. Plyometric training, when progressed conservatively with proper technique, is an efficient way to develop and maintain power across the lifespan.
