How to perform Sledgehammer Swings
- You will need a tire and a sledgehammer for this exercise. Stand in front of the tire about two feet away from it with a staggered stance. Grip the sledgehammer.
- If you are right handed, your left hand should be at the bottom of the handle, and your right hand should be choking up closer to the head.
- As you bring the sledge up, your right hand slides toward the head; as you swing down, your right hand will slide down to join your left hand. Slam it down as hard as you can against the tire. Control the bounce of the hammer off of the tire.
- Repeat on the other side.
Muscles worked
- Core (primary): braces the trunk and resists twisting to protect the spine.
- Calves (secondary): points the foot to power push-off and steady the ankle.
- Forearms (secondary): controls your grip and keeps the wrist steady under load.
- Back (secondary): pulls the arms down and toward the torso and keeps the spine stable.
- Shoulders (secondary): raises and rotates the arms and drives everything overhead.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Brace as if about to take a light punch and breathe shallowly — don't hold your breath for the whole set.
- Set the seat and pads so the machine's pivot lines up with the joint you're training before your first rep.
- Land softly through the whole foot with bent knees to absorb the force, and reset fully between reps.
- Stop a rep or two short of failure on most sets to keep form clean and recover faster.
Common mistakes
- Cranking with the hip flexors or neck instead of moving from the trunk.
- Leaving the seat or range on a setting that forces the joint into an awkward angle.
- Landing stiff-legged or with locked knees, which spikes the load on the joints.
