Knee Circles
Also works: Hamstrings · Quadriceps
Stand with your feet together, hands resting just above the kneecaps, and draw slow circles with both knees at once. It is a joint-preparation drill rather than a stretch: it moves the knee through flexion, extension and a little rotation under no load, and it takes about thirty seconds.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Stand with your feet and knees touching, toes pointing straight ahead.
- Place your palms just above the kneecaps, fingers pointing down, so your hands guide rather than push.
- Bend both knees slightly to unlock them — start from a soft quarter-bend, not from locked-out legs.
- Keep your weight even across both feet and your heels on the floor throughout.
Every rep
Breathing & tempo — Breathe normally and continuously — roughly one full breath per circle. There is no bracing and no held breath in this drill.
How much, how often
Where to start, and what to change when it stops being hard.
Bodyweight only, and the knees stay barely bent throughout. Ten to fifteen circles each direction, once at the start of any session involving the legs. Daily is fine. There is nothing to progress here — when this feels easy, that is the correct outcome, and the next step is loaded work like bodyweight squats, not more circles.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Slow to three seconds per revolution and make the circle as large as you can while keeping both heels down. Ten slow circles do more than forty fast ones.
Rest your palms there for feedback only. Loading a bent knee from the top compresses the patella against the femur, which is exactly the surface that complains in most knee pain.
Shorten the circle until you can keep both heels flat. If you want ankle range, do ankle circles separately where you can actually control the joint.
Use it to warm up, then go and load the joint. Knee pain responds to progressive quad and hamstring strengthening; unloaded circles give you a few comfortable minutes, not an adaptation.
Why bother
Knee cartilage has no blood supply. It gets its nutrients from joint fluid being squeezed in and out as the joint moves, which is why a knee feels stiff after two hours in a chair and loose after a few minutes of walking. Circling the knees under bodyweight is the fastest way to trigger that exchange before you ask the joint to do anything harder.
Set your expectations honestly: this is not building range, strength or stability. Thirty seconds of unloaded circles will not change what your knee can do next month. What it does is make the first working set feel like the third one, which is a real and modest benefit.
Where it fits
First thing in a lower-body warm-up, before ankle circles and bodyweight squats and well before any bar comes out of the rack. Ten to fifteen circles each direction is the whole dose. It also works as a desk break on a long day, and there is no reason not to do it daily.
If this one isn't it
No kit, too hard, or too easy — here's where to go instead.

Asked and answered
Is this safe if my knees click?
Painless clicking or grinding is extremely common and is not evidence of damage — it is usually gas moving in the joint or a tendon passing over bone. Keep going. Clicking that comes with a sharp catch, swelling afterwards, or a feeling that the knee might give way is a different signal and worth getting looked at.
How is this different from ankle circles?
Knee circles bend and straighten the knee while the foot stays planted, so the movement happens mainly at the knee and hip. Ankle circles move the foot in the air with the knee still. They warm different joints and neither substitutes for the other — if you are about to squat, do both, in about forty seconds total.
Should I do this before or after training?
Before, and only before. This is joint preparation with no lasting effect, so putting it at the end of a session wastes it. Afterwards you want static holds for the calves and hamstrings, where the longer holds actually do something for accessible range.
