Running does not wear knees out
Recreational runners show lower rates of knee osteoarthritis than sedentary people, not higher.

The skills a knee is actually for: running mechanics, stairs at speed, and getting up from the ground.
Recreational runners show lower rates of knee osteoarthritis than sedentary people, not higher.
Getting out of a chair takes around 90–100° of bend and a strong quad. Time yourself over the thirty days.
Lowering off a step under control tests quad strength, hip control and confidence in one movement.
Three couplets · two rounds · twelve minutes · a knee that carries you
Land under the hips on the ball of the foot, knees driving; count the left foot only.
Easier marching · Harder faster turnover
Knee up, toe up, heel up; skip with a quiet, elastic contact.
Easier marching with the same shape · Harder higher and faster
Up the stairs on the balls of the feet, one at a time and fast; walk down.
Easier walk up · Harder two at a time
Drive off the step to a soft landing on top; step down under control.
Easier fast step-ups · Harder higher step
From lying, get to standing any way you can and lower back down; count rounds.
Easier use both hands · Harder hands off the floor
Sit to your deepest squat, hold one second, stand tall — no hands.
Easier hold a support · Harder hold a backpack
Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.
