Target muscles
The deltoids and triceps drive the overhead press, but the offset mace head turns it into far more than a vertical push — as the head tips and swings to one side, the obliques and deep core fight hard to keep the trunk from rotating and the upper back works to control the lever. The forearms and grip manage the long handle throughout, and the traps and serratus stabilise the shoulder blades at lockout. Alternating the swing between sides makes it a demanding press-and-anti-rotation combination.
How to perform
Setup
Stand tall with the mace in a front rack, hands stacked low on the handle and the core braced. Set the feet hip- to shoulder-width for a stable base and pull the ribs down.
Execution
Press the mace overhead, then let the head tilt and travel down behind one shoulder under control, resisting the trunk's urge to rotate with that side's obliques. Pull it back up to overhead, then flow to the other side, alternating the swing left and right with each press cycle. Keep the press path strong and the catch at lockout solid, and let the core — not the lower back — absorb the offset pull each rep. Move deliberately; this is a controlled flow, not a fling.
Common mistakes
- Arching the lower back to muscle the press instead of bracing the core against the offset head.
- Letting the trunk rotate and lean as the head swings to one side.
- Losing control of the head behind the shoulder so it yanks the joint.
- Going too heavy for a movement that lives on control, not load.
Progressions and regressions
Regress to a strict mace front press or the mace 10-to-2 to build the overhead and offset-control pieces separately before combining them. Progress by adding load, increasing the range of the side swing, or flowing it into a longer sequence with 360s. It is an advanced movement — earn it with solid overhead mace control first.
Programming notes
Program it as advanced shoulder and core work, 2-3 sets of 6-10 controlled cycles per side, when the shoulders are fresh and your overhead position is honest. It builds overhead stability and anti-rotation strength simultaneously, so it slots well into athletic or functional sessions. Skip it on days when overhead pressing is uncomfortable — the offset load is unforgiving of a cranky shoulder.
