The right weight
Rule of thumb: the bag should weigh about half your body weight. Too light and it swings like a pendulum; too heavy and it's harsh on wrists and joints.
Filling types
- Fabric/fiber: even distribution, the favorite for technical striking.
- Sand: very hard, only for the already conditioned.
- Water (Aqua Bag): great feedback, protects the joints.
Anchoring
Use a ceiling mount on a load-bearing beam or a free-standing frame with a weighted base.
Disclaimer: always verify the load capacity of the anchor point. A falling bag is a serious hazard.
