IRON KNEE ACADEMY
When it comes to running without knee pain, a great strength protocol is only half the battle.
How you bridge the gap between rehab, plyometrics and running is just as critical.
To safely get back to running properly again, you must pass 3 sequential baseline tests. Think of these as your green lights to keep moving forward.

TEST 1
Before you lace up for a run, your knee must tolerate force absorption safely.
THE TEST: Perform 5 controlled drop & sticks. Focus on a soft, quiet landing and “absorbing” the impact.
TEST 2
The Spring Test
The poison is the antidote. Impact created the problem, but controlled impact is also the solution.
THE TEST: Perform 20 ankle hops. Focus on quick contact bounces and pushing off the big toe.
THE GREEN FLAG: Smooth, reactive bounces with zero to mild, fading sensation (<4/10). This means your achilles and patellar tendons are storing and releasing elastic energy effectively.
TEST 3
The 24-Hour Recovery Window
The ultimate test of plyometrics happens the next day.
THE GREEN FLAG: If your pain settles back down to absolute 0 within 24 hours (12 hours is even better), your knee successfully tolerated that load. You are clear to start your run/walk return-to-run progression.
