How to Prevent Patellar Tendon for Good

The training and strength levers that keep patellar tendon from coming back — built for runners.

Stop the Cycle

Patellar Tendon is rarely a one-time event — it returns when the underlying causes aren't addressed. Build these into your weekly routine.

  • Quad strength 2-3x/week year-round
  • Progress jumping and sprint volume gradually
  • Address calf mobility
  • Strength through full range

Strength Work That Actually Helps

Most prevention failures come from skipping consistent strength. The exercises below are the ones with the best evidence for patellar tendon.

  • Spanish Squat — 3 sets of 45s isometric holds, daily
  • Heavy Slow Squats — 3 sets of 6-8, 2-3x/week
  • Single-Leg Decline Squat — 3 sets of 10, 2x/week
  • Calf Stretching — 30s per side, daily

Training Rules to Follow

  • Cap weekly mileage jumps at 10%
  • Run easy on easy days — most runners run their easy too fast
  • Replace shoes between 350-500 miles depending on body weight and surface
  • Build one strength session into every training week, year-round
  • Sleep at least 8 hours during heavy training blocks
