Stairs need range
Climbing stairs takes roughly 85–90° of knee bend; descending takes more. Range is a daily requirement, not a luxury.

Real-world load: bags, stairs and a knee that can lower a body weight under control.
Climbing stairs takes roughly 85–90° of knee bend; descending takes more. Range is a daily requirement, not a luxury.
Regular walking reduces pain and slows functional decline in knee osteoarthritis. Ten minutes after this session counts.
Calf strength absorbs load before it reaches the knee. Weak calves send that work upstairs.
Three couplets · two rounds · twelve minutes · a knee that carries you
Pack on; whole foot on each step, drive through the heel, walk down slowly.
Easier bodyweight · Harder heavier
Pack at the chest; up in one second, down in three, whole foot on the step.
Easier bodyweight · Harder higher step
Two heavy bags; walk tall, short quick steps, shoulders quiet.
Easier lighter · Harder heavier
Two bags at the shoulders; sit down with the elbows high and the chest tall.
Easier one bag at the chest · Harder heavier
Walk backwards with small controlled steps — it loads the quad and spares the kneecap.
Easier hold a support · Harder up a slight slope
Lower into a lunge for four seconds, then step out and reset — no drive up.
Easier three seconds · Harder hold a backpack
Each couplet: 60 s scored → the loading set → 10 s to move on. Done at 12:00.
