Wrist CARs: A Complete Guide
Quick Intro
Wrist CARs is a wrist mobility drill performed by extending one arm in front and, with the opposite hand stabilizing the forearm, slowly rotating the wrist through its full range under active muscular control. Stabilizing the forearm firmly is what isolates the movement to the wrist joint alone, rather than letting the whole forearm rotate and quietly do the wrist’s job for it.
Equipment Needed
No equipment is required.
Why It Matters
The drill asks the wrist to move through four distinct positions, flexion, radial deviation, extension and ulnar deviation, as separate deliberate stops rather than one loose circle. Because the opposite hand actively stabilizes the forearm, the wrist gets no help, which gives a clear read on how much of its own range it can generate. It works well as a regular drill for anyone doing pressing, carrying or gymnastics work, since all three ask the wrist to hold load through positions this drill rehearses unloaded first.
When to Do It
Place this early in a session, as a warm-up before pressing, carrying, gymnastics work or any activity that loads the wrist through end ranges. It also works well as a standalone drill for anyone who wants a clean baseline read on wrist mobility, isolated from any grip or load. Anyone with a diagnosed wrist condition or a history of wrist injury should get clearance from a doctor or physical therapist before working the joint through a full active rotation.
Getting Ready
Extending one arm in front and using the opposite hand to firmly stabilize the forearm for a moment first confirms the wrist is isolated before the first rotation. Trying one slow pass through the four positions is a reasonable way to gauge how much range feels available that day.
Step-by-Step Instructions
- Extend one arm in front and stabilize the forearm firmly with the opposite hand.
- Flex the wrist, moving slowly under active control.
- Rotate into radial deviation, tilting the hand toward the thumb side.
- Extend the wrist, then rotate into ulnar deviation, tilting toward the pinky side.
- Repeat for 3-5 full CARs per direction, then switch to the other wrist.
How Many, How Often
| Level | CARs (per direction, per wrist) |
|---|---|
| Beginner | 3 |
| Intermediate | 4 |
| Advanced | 5 |
Keeping the forearm stabilized and still matters more here than how far the wrist appears to travel. Letting the whole forearm rotate along with the hand is what turns an isolated wrist drill into a forearm movement.
Modifications and Variations
Harder: Wrist CARs — Weight Bearing. Placing the hand flat on the floor and bearing partial bodyweight through the arm before rotating adds a strength-through-range demand on top of the same wrist positions, a fair progression once the unloaded version feels smooth.
Common Mistakes to Avoid
Letting the forearm rotate along with the wrist. Once the stabilizing hand loosens its grip on the forearm, the whole arm can rotate to fake a bigger-looking wrist circle. Keeping that stabilizing hold firm is what isolates the movement to the joint the drill is meant to train.
Blurring the four positions into one loose circle. Moving quickly through flexion, radial deviation, extension and ulnar deviation makes it easy to skip whichever direction feels stiffest without noticing. Treating each position as a distinct, deliberate stop keeps every direction in the drill.
Rushing through the repetitions. A fast pace trades control for speed and makes it harder to feel where the range runs out in each direction. A slow, deliberate tempo gets more out of the drill.
After Your Set
A few gentle wrist shakes are a reasonable way to close out a set that just asked the wrist to work through its full isolated range.
Going Deeper
The marker of progress here isn’t how fast the four positions can be cycled through, it’s whether each one, especially whichever direction tends to feel stiffest, gets an equally full, equally controlled range. Once that balance holds across all four positions, the weight-bearing version is a reasonable next step, since it adds load on top of range that is already there unloaded. Chasing speed before every direction feels equally open usually just means the stiffest one is being quietly shortchanged.
How to Know You’re Improving
- All four directions feel roughly equally open, with no single one trailing the rest.
- The forearm stays still while the wrist does the moving.
- The range in the stiffest direction gradually opens up across sessions.
- Both wrists manage a similarly sized, similarly controlled rotation.
- The weight-bearing version starts to feel like a reasonable next step.
Muscles Worked
- Forearm Flexors (the muscles of the inner forearm, driving the flexion phase of the rotation)
- Extensor Carpi Radialis (a forearm muscle on the back of the wrist, driving the extension and radial deviation phases)
- Flexor Carpi Radialis (a forearm muscle on the palm side of the wrist, active through the flexion and radial deviation phases)
- Brachioradialis (a forearm muscle running from the elbow to the wrist, assisting the controlled rotation throughout)
FAQ
Why stabilize the forearm with the other hand? Without that stabilizing hold, the whole forearm can quietly rotate along with the hand, making the wrist’s own range look bigger than it is. Holding the forearm still is what keeps the drill isolated to the joint it’s meant to train.
Why does this drill treat the four positions as separate stops instead of one continuous circle? Breaking flexion, radial deviation, extension and ulnar deviation into distinct, deliberate positions makes it much easier to notice if one of them is being skipped or rushed past. Working through separate stops makes a weak or stiff direction obvious in a way a single sweeping circle tends to hide.
Is this the same as the weight-bearing wrist rotation used before push-ups? Related but different, since this unloaded version isolates pure joint range with the forearm stabilized, while the weight-bearing version adds bodyweight through the hand during a similar rotation. Both work through a related range, but under very different demands.
Is one direction, often ulnar deviation, noticeably stiffer than the others normal? Yes, that’s a common pattern, since ulnar deviation tends to have less natural range than the other three directions for many people. Working it just as deliberately as the more open directions is worth the extra attention.
Can this be done daily, especially before pressing or carrying work? Yes, since it’s a slow, zero-impact, zero-load drill, making it reasonable to include as a regular warm-up before any activity that will load the wrist later in the session.
