Mace 10-to-2 — Short Arc: A Complete Guide
Quick Intro
Mace 10-to-2 — Short Arc is a shoulder mobility and control drill performed by holding the mace vertically behind the head and levering it through a smaller side-to-side arc, roughly 11-to-1, reducing the lever demand on the shoulder while still training the same pattern the full 10-to-2 range uses. Keeping the mace closer to the body’s center through this shorter path is what cuts the torque at each end range down to a manageable level.
Equipment Needed
A light Persian mace, also called a gada.
Why It Matters
This is a smaller version of the same behind-the-head lever pattern the full 10-to-2 trains. Because the arc travels through a reduced range, the torque at each end drops significantly compared to the full pattern, making this an entry point for anyone whose shoulders aren’t ready for the complete lever yet. It works well as a way to build the pattern and the deceleration habit before taking on the full arc’s greater torque demand.
When to Do It
Place this early in a session, as preparation for building toward the full 10-to-2 pattern, or as a starting point for anyone new to behind-the-head mace work. It also works well as a standalone drill for building comfort with a loaded implement behind the head. Anyone with a diagnosed shoulder condition should get clearance from a doctor or physical therapist before levering a weighted implement behind the head, even through a reduced range.
Getting Ready
Holding the mace vertically behind the head, one hand high and one low, for a moment first settles the position before the first pass. Trying one slow, small movement toward one side is a reasonable way to gauge how the reduced arc feels that day.
Step-by-Step Instructions
- Position the mace vertically behind the head, grip high with one hand, low with the other.
- Lever the mace through a smaller arc, roughly toward 11 o’clock.
- Control the deceleration deliberately, even at this shorter range.
- Return through the same reduced arc toward 1 o’clock.
- Work through 10-15 reps each direction, switching which hand sits high every set.
How Many, How Often
| Level | Reps (per direction) |
|---|---|
| Beginner | 10-11 |
| Intermediate | 12-13 |
| Advanced | 14-15 |
Controlling the deceleration at each end deliberately matters more here than how quickly the arc completes. A short arc doesn’t mean a careless one, since the same active control the full pattern demands still applies at this reduced range.
Modifications and Variations
Harder: Mace 10-to-2. Extending the same side-to-side lever through the full 10-to-2 range, rather than the shorter 11-to-1 path, adds more torque at both end ranges once this shorter version feels completely controlled.
Common Mistakes to Avoid
Treating the shorter arc as a reason to stop actively controlling it. A reduced range still needs the same deliberate deceleration at each end that the full pattern demands, and letting the mace swing carelessly through this shorter path defeats its purpose as an entry point. Active control matters here just as much as in the full version.
Rushing straight to the full 10-to-2 range. Skipping this shorter version and starting directly with the complete arc asks the shoulder to manage full torque before the pattern itself has been learned safely. Building comfort with the reduced range first makes that eventual step up considerably more manageable.
Always leading with the same hand position. Keeping one hand high every set, even at this shorter range, trains only one direction of the lever. Switching hand positions each set builds the pattern evenly on both sides from the very start.
After Your Set
A few gentle shoulder rolls and a brief overhead shoulder stretch are a reasonable way to close out a set that just asked the shoulders to control a reduced-range behind-the-head lever.
Going Deeper
The marker of progress here isn’t how many reps get completed, it’s whether the deceleration at each end of this shorter arc feels active, not passive. Once that control holds steady with both hand positions, extending toward the full 10-to-2 range becomes a reasonable next step. Rushing to the full arc before this shorter one is controlled usually just means the torque increase arrives before the shoulder is ready to manage it.
How to Know You’re Improving
- The deceleration at each end of the shorter arc feels active and controlled.
- Both hand positions feel similarly comfortable.
- The pattern stays smooth through repeated sets.
- Both directions manage a similarly controlled short arc.
- Extending toward the full 10-to-2 range starts to feel like a reasonable next step.
Muscles Worked
- Posterior Deltoid (the back of the shoulder cap, active through the reduced behind-the-head lever)
- Rotator Cuff (the small muscle group deep at the shoulder joint, controlling the deceleration at each end)
- Trapezius (the muscle spanning the upper back and neck, stabilizing the shoulder blades throughout)
- Lateral Deltoid (the side of the shoulder, working through both ends of the shorter lever)
FAQ
Does a shorter arc still train the mace lever pattern? Yes. Keeping the mace closer to the center of the body through this reduced range still trains the same behind-the-head lever mechanics the full 10-to-2 pattern uses, just with less torque at each end. That is what makes it an entry point rather than a different exercise.
Why does the range stop at roughly 11-to-1 instead of the full 10-to-2? That smaller range is what keeps the torque at each end manageable for a shoulder that isn’t ready for the complete lever’s demand yet, while still building the same deceleration skill the full pattern requires.
Is this a reasonable starting point for someone new to mace work? Yes, the reduced torque at each end range makes this a sensible first version of the behind-the-head lever pattern, letting the shoulder build comfort with the movement before the full arc’s greater demand gets introduced.
Does the reduced arc mean less benefit for the shoulder? No, the same active deceleration skill and the same behind-the-head positioning are both being trained, just at a range the shoulder can currently manage safely. That skill transfers directly once the full arc gets introduced.
When is it time to move to the full 10-to-2 arc? Once this shorter range feels completely controlled at both ends with either hand position, extending toward the full 10-to-2 pattern is a reasonable next step.
