Wrist CARs — Weight Bearing: A Complete Guide
Quick Intro
Wrist CARs — Weight Bearing is a wrist mobility drill performed with one hand flat on the floor, fingers spread, bearing partial bodyweight through the arm while slowly rotating the loaded wrist through as much range as the weight-bearing position allows. Loading through the whole hand evenly before starting the rotation is what turns this into a strength-through-range drill under bodyweight, rather than the free, unloaded circle of the standard wrist CAR.
Equipment Needed
No equipment is required, though a yoga mat is a reasonable addition for comfort under the loaded hand.
Why It Matters
The drill asks the wrist to control a much smaller range under weight rather than a large range with no resistance, so strength and endurance matter more here than in the unloaded version. Because the loaded wrist has far less available range than its open-air counterpart, this version measures and builds a different quality, control and strength through a working range under load. It works well as a direct way to prepare the wrist for the demands of crawling, all-fours work or any position that puts weight through the hand.
When to Do It
Place this early in a session, as preparation for crawling patterns, all-fours work or any activity that puts bodyweight through the hand. It also works well as a progression for anyone who has already built comfort with the standard unloaded wrist CAR and wants to add a loaded component. Anyone with a diagnosed wrist condition, carpal tunnel symptoms or a history of wrist injury should get clearance from a doctor or physical therapist first, since this version puts bodyweight through the joint.
Getting Ready
Placing one hand flat on the floor with the fingers spread wide and shifting a little weight onto it for a moment first confirms the load is there before the first rotation. Trying one small, slow rotation is a reasonable way to gauge how much loaded range feels available that day.
Step-by-Step Instructions
- Place one hand flat on the floor, fingers spread wide.
- Bear partial bodyweight through the arm.
- Slowly rotate the loaded wrist through as much range as the position allows.
- Keep the movement small and controlled, respecting the reduced range under load.
- Repeat for 3-5 slow rotations per direction, then switch to the other wrist.
How Many, How Often
| Level | Rotations (per direction, per wrist) |
|---|---|
| Beginner | 3 |
| Intermediate | 4 |
| Advanced | 5 |
Loading through the whole hand evenly with the fingers spread wide matters more here than how far the wrist rotates. A loaded wrist has less range available than the unloaded version, and respecting that smaller range is what keeps this a strength-through-range drill.
Modifications and Variations
Easier: Wrist CARs. Rotating the wrist with no weight through the hand removes the loaded demand, a more approachable entry point for anyone whose wrist isn’t ready to bear weight through a rotation yet.
Common Mistakes to Avoid
Loading the hand unevenly. Letting the weight concentrate through one part of the hand rather than spreading evenly across the spread fingers changes how the joint experiences the same rotation. Even loading through the whole hand keeps the drill working the way it’s designed to.
Expecting the same range as the unloaded version. Comparing this rotation’s size to the standard wrist CAR misses the point, since a smaller range under load is expected and appropriate here. The drill is better judged by control and comfort than by matching the unloaded range.
Rushing the rotation. Moving quickly through a loaded rotation risks pushing the wrist past the smaller range it can control under weight. A slow, deliberate pace respects how much less forgiving a loaded position is compared to an open-air one.
After Your Set
A few gentle wrist shakes and a brief seated wrist stretch, hands relaxed and unloaded, is a reasonable way to close out a set that just asked the wrist to rotate under bodyweight.
Going Deeper
The marker of progress here isn’t how large the loaded rotation gets, it’s whether the wrist can move through its current available range smoothly, with the weight staying evenly distributed across the spread fingers the whole time. Once that control feels solid, the loaded range itself tends to expand gradually across sessions as a natural result. Chasing a bigger rotation before the load stays even usually just pushes the wrist into a range it cannot yet manage under weight.
How to Know You’re Improving
- The loaded rotation can move through a slightly larger range without discomfort.
- The weight stays evenly distributed across the spread fingers throughout.
- Both wrists manage a similarly sized, similarly controlled loaded rotation.
- The wrist feels more comfortable bearing weight in an all-fours position generally.
- Crawling or other all-fours work starts to feel easier on the wrists specifically.
Muscles Worked
- Forearm Flexors (the muscles of the inner forearm, controlling the wrist through the loaded rotation)
- Extensor Carpi Radialis (a forearm muscle on the back of the wrist, active through the loaded extension phase)
- Flexor Carpi Radialis (a forearm muscle on the palm side of the wrist, active through the loaded flexion phase)
- Brachioradialis (a forearm muscle running from the elbow to the wrist, assisting the controlled rotation under load)
FAQ
Why is the range so much smaller here than in the unloaded wrist CAR? Bearing weight through the hand restricts how far the wrist can rotate compared to moving freely in the air, since the joint has to manage load and range at the same time. That smaller range under load is expected, not a sign of doing the drill wrong.
Why does spreading the fingers wide matter? Spread fingers distribute the bodyweight more evenly across the hand, which changes how the wrist experiences the same rotation compared to fingers bunched together concentrating pressure into a smaller area. Even loading is part of what keeps the drill working as intended.
Is this the same as the wrist circles used before push-ups? Related, since both bear weight through the hand, but this drill treats flexion, radial deviation, extension and ulnar deviation as distinct CARs positions, while a wrist circle moves continuously through an orbiting path. Both build loaded wrist tolerance, just through slightly different movement structures.
Is a pinching sensation during the loaded rotation something to push through? No, a pinching sensation signals the current loaded range has outrun what the joint can comfortably handle. Keeping the rotation smaller until that pinching resolves is the better approach.
Should the unloaded version be comfortable before trying this one? Yes, since this version builds directly on the same rotational range explored without weight, and starting here without that base risks pushing an unprepared wrist into a demanding loaded position. Building comfort with the unloaded version first is the safer progression.
