Illustrated guide to the Mace Splitting Wood exercise

Mace Splitting Wood

The abs and obliques drive an explosive overhead-to-down chop of a steel mace, mimicking splitting logs with an axe.

Level: Intermediate

Primary: Abs

Secondary: Back - Upper Shoulder

Movement: Compound

Tags: Explosive Rotational

Type: Functional Fitness (Obstacle & Hybrid)

Equipment: Mace

Target muscles

The rectus abdominis and obliques are the engine here, flexing and rotating the trunk to drive the offset mace head from overhead down past one hip in a powerful chop. The lats and shoulders accelerate the head downward, the forearms and grip control the long lever through the fast arc, and the hips and glutes anchor the movement and contribute to the snap. It trains explosive trunk flexion and rotation — the axe-swing pattern of splitting wood.

How to perform

Setup

Stand with feet shoulder-width or slightly wider, holding the mace handle with both hands and raising the head up overhead, arms extended. Brace the core hard and set a flat, strong spine before you swing.

Execution

Drive the mace down and across toward one hip by forcefully flexing and rotating the trunk, as if burying an axe into a log between your feet or just outside one knee. Let the abs and obliques pull the head down — the arms guide rather than yank — and hinge slightly at the hips to absorb the finish. Decelerate the head at the bottom, then control it back up overhead and reset for the next chop. Keep the spine braced through the snap and target the same point each rep before switching sides.

Common mistakes

  • Swinging with the arms and shoulders while the core stays passive, removing the explosive trunk action.
  • Rounding the lower back violently at the bottom instead of hinging the hips to absorb the chop.
  • Letting the mace head crash out of control rather than decelerating it at the finish.
  • Choosing a load too heavy to chop with real speed and a braced spine.

Progressions and regressions

Regress to a lighter mace, a slower controlled chop, or a half-kneeling version to learn the trunk-driven pattern. Progress by adding load, increasing the speed of the chop, or alternating sides for conditioning. A cable or band wood-chop is a smooth on-ramp before loading the offset mace head.

Programming notes

Program it as explosive core and rotational power work, 3 sets of 6-10 per side, balanced left and right. Place it when you are fresh so the chops stay fast and crisp, and keep the load moderate so the spine stays safe under the speed. It suits rotational and combat athletes and finishes a core day well alongside an anti-rotation hold.
