Mace 10-to-2: A Complete Guide
Quick Intro
Mace 10-to-2 is a shoulder mobility and control drill performed by holding a Persian mace vertically behind the head, one hand high on the handle and one low, then levering the implement side to side from the 10 o’clock position to the 2 o’clock position like a pendulum behind the head. Controlling the deceleration with the shoulders at each end of the arc keeps this a control drill, not a swing that simply gets caught at the last second.
Equipment Needed
A Persian mace, also called a gada, light enough to stop under control at each end.
Why It Matters
The drill is built around decelerating a long lever at two separate end ranges across many reps. Because the mace stays behind the head the entire time, never arcing overhead or across the body, the shoulders have to manage torque at both the 10 o’clock and 2 o’clock ends without ever getting a moment where the implement is close to the body’s centerline. It works well as a way to build end-range shoulder control under a long lever.
When to Do It
Place this early in a session, once a light general warm-up has settled the shoulders, as preparation for any activity that asks the shoulder to decelerate a load at end range. It also works well as a standalone drill for anyone building comfort with behind-the-head mace positions before combining them into a fuller flow. Anyone with a diagnosed shoulder condition should get clearance from a doctor or physical therapist before levering a weighted implement behind the head.
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 lever. Trying one slow, small pass from the middle toward one side is a reasonable way to gauge how much control feels available at end range that day.
Step-by-Step Instructions
- Hold the mace vertically behind the head, one hand high, one low.
- Lever the mace toward the 10 o’clock position.
- Control the deceleration at that end range.
- Lever back across to the 2 o’clock position.
- Perform 10-15 reps per direction, switching hand positions each set.
How Many, How Often
| Level | Reps (per direction) |
|---|---|
| Beginner | 10-11 |
| Intermediate | 12-13 |
| Advanced | 14-15 |
Controlling the deceleration at each end of the arc with the shoulders matters more here than how wide the pendulum swings. The long lever means even a light mace generates significant torque at end range, and letting the implement’s own momentum stop the arc defeats the entire purpose of the drill.
Modifications and Variations
Easier: Mace 10-to-2 — Short Arc. Levering through a smaller side-to-side arc, roughly 11-to-1, reduces the torque demand at each end while still training the same pattern, a more approachable entry point for anyone whose shoulders aren’t ready for the full lever yet.
Harder: Mace 10-to-2 — Heavier Implement. Performing the same side-to-side lever pattern with a heavier mace substantially increases the torque both hands have to control at each end of the arc, a clear step up once the standard load feels smooth.
Common Mistakes to Avoid
Letting the mace’s weight yank the arms at end range. Once momentum, not the shoulders, decides where the arc stops, the drill has stopped being a control exercise and become a swing that just gets caught. Actively decelerating with the shoulders at both the 10 o’clock and 2 o’clock ends is the skill being trained.
Always leading with the same hand position. Keeping one hand high and the other low every set trains only one direction of the lever, leaving the reversed grip undertrained. Switching hand positions each set is what builds control evenly on both sides.
Rushing through the middle of the pattern. Moving quickly through the center to get to the next end range skips the part of the arc where the grip transition is easiest to feel and correct. A controlled pace matters through the entire pattern, at the middle as well as the ends.
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 decelerate a long lever at two separate end ranges.
Going Deeper
The marker of progress here isn’t how wide the pendulum swings, it’s whether the deceleration at both the 10 o’clock and 2 o’clock ends stays controlled by the shoulders rather than by the mace’s own momentum. Once that control holds steady with both hand positions, a heavier mace becomes a reasonable next step. Chasing a wider arc while the ends stay uncontrolled usually just means the shoulders are absorbing a stop they should be actively creating.
How to Know You’re Improving
- The deceleration at both end ranges is controlled by the shoulders, not the mace’s momentum.
- Both hand positions, high-right and high-left, feel similarly controlled.
- The transition through the middle of the pattern stays smooth and unhurried.
- The arc can widen slightly without either end feeling uncontrolled.
- A heavier mace starts to feel like a reasonable next step.
Muscles Worked
- Posterior Deltoid (the back of the shoulder cap, active through the 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 lever)
- Rhomboids (the muscles between the shoulder blades, active as the mace shifts side to side)
- Erector Spinae (the muscles running along the length of the spine, keeping the torso stable through the lever)
FAQ
Why does the mace stay behind the head the whole time, rather than circling overhead? Keeping the implement fixed behind the head isolates the demand to decelerating a long lever at two separate end ranges, a different skill from carrying an implement through a continuous circle where it’s rarely at a dead stop. That end-range control is the specific thing this drill trains.
Why switch hand positions every set? Each hand position, high or low on the handle, manages a different side of the lever, and switching every set is what trains both directions evenly rather than building control on only one side.
Is the short-arc version a good place to start? Yes, reducing the arc from the full 10-to-2 range to a smaller pendulum cuts down the torque at each end considerably, making it a sensible starting point for anyone whose shoulders need to build tolerance before taking on the full lever.
Is some shoulder fatigue after a set normal? Yes, decelerating a long lever at two separate end ranges repeatedly is hard work, and some fatigue afterward is expected. Should a sharp pain appear anywhere in the shoulder instead, that calls for backing off the drill and getting it checked by a doctor or physical therapist.
When is it time to move up to a heavier mace? Once the standard implement’s full 10-to-2 arc feels smooth and controlled at both ends with either hand position, a heavier mace is a reasonable next step.
