Struggling with stiff, painful knees after 40? Here are 3 equipment-free exercises I've used for the past 14 years (I'm 54!!) to bulletproof my knees and obtain deep knee flexion, extension, and strength.

In this video, you’ll learn:
👉🏻 Why ignoring knee stiffness accelerates joint breakdown (and how daily motion prevents permanent loss of function).
👉🏻 Critical tibia rotation drills to unlock full knee range (internal/external rotation fixes).
👉🏻 A 5-second terminal extension stretch that targets restricted knee straightening.
👉🏻 The progressive half side bridge that bulletproofs knees under load (basic → advanced variations).

These 3 Knee Exercises are perfect if you’re an athlete, fitness enthusiast, or anyone wanting to experience pain-free squats, running, or daily movement.

Remember: “Motion is lotion”—consistent movement builds resilience, not age-related decline.
