Higher injury risk. Read the safety notes before adding weight.

How to do it
- Stand with your feet slightly wider than hip-width, knees softly bent.
- Hold the bag’s main handles with the bag in front of your waist.
- Swing the bag upward toward one shoulder.
- Guide the bag behind your head with your elbows bent.
- Continue the circle around your opposite shoulder.
- Return the bag to the front of your waist to complete the repetition.
Form cues
- Keep your wrists firm.
- Look straight ahead.
- Let your heels pivot with your turn.
- Breathe throughout the spin.
Common mistakes
- Pulling with only your armsUse a coordinated hip and trunk turn to help drive the bag around.
- Ducking under the bagUse a lighter bag that you can guide around your head without ducking.
- Jerking through the frontMaintain a steady rhythm rather than yanking the handles to start each circle.
Safety
An uncontrolled bag can strike your head or neck, and a slipping grip can send it into nearby people or objects. Excessive load or fatigue can also strain your shoulders or lower back as you redirect its momentum.
- Inspect the handles and seams before use.
- Clear enough space for the bag’s full arc, including overhead and behind you.
- Start with a light bag for a few controlled circles before attempting continuous sets.
- End the set before your grip tires by gradually slowing the bag in front before lowering it or reversing direction.
If you have shoulder, neck, or back pain, or limited overhead mobility, get guidance from a physiotherapist before attempting spins.
