Swinging a sledgehammer onto a tire loads the trunk through a violent high-to-low diagonal while the rebound tests your grip and forearms on every strike. Alternate which hand leads so both sides learn the pattern, and count strikes per side rather than chasing the clock; the quality of each swing is the exercise.

How to do the Sledgehammer Tire Slam

  1. Stand with your feet shoulder-width apart and hold the sledge hammer with both hands.
  2. Engage your core and keep your back straight.
  3. Swing the sledge hammer down towards the ground, using your core and upper body strength.
  4. As you swing down, pivot your hips and transfer the force to the hammer.
  5. Repeat for the desired number of repetitions.

Tip: Pivot on the back foot and let the hips turn with the shoulders so the rotation is shared across the whole body.

Muscles worked

Primary

Abs · Core

The obliques rotate the torso and resist the return, and you should feel the side of the waist tighten on each side as you turn.

Secondary

Common mistakes

  • Twisting from the lower back — the rotation should come from the mid back and hips; keep the lower back neutral and let the hips turn with you on standing variations.
  • Using the arms to swing — on cable and band rotations the arms stay locked out in front of you and the torso does the turning.
  • Rushing the reps — control the return and pause briefly at the end range on each side instead of bouncing back and forth.
  • Loading barbell twists heavy — gravity barely resists rotation, so keep barbell twists light and controlled, and use a cable or band when you want real rotational load.

Where it fits in a workout

Rotations work at the end of a session with the other core work, or as a warm-up before throws and rotational sports. Superset cable rotations with a cable side bend or pull-through on the same stack.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
