exercise heavy bag

Common types: hanging/unfilled bags (traditional canvas or leather bags hung from a mount), water-filled (aqua) bags (filled with water for adjustable weight/feel), freestanding bags (a heavy fillable base or stand lets you place the bag anywhere), and hybrid water bags (inner air core with a neoprene cover combining water damping with air rebound).

Common materials: PVC, neoprene, polyester, and PU/PU leather for exterior coverings; internal layers often use foam or reinforcing materials to improve durability and rebound.

Sizes range from compact short bags up to full‑height freestanding bags. Example heights mentioned include around 23", 28", 44", 65", with some freestanding options reaching up to about 70".

Common accessories include adjustable hanging chains and safety/insurance buckles, water hoses or pumps for water bags, and some hanging sets that bundle gloves and hand wraps. Many product listings offer complete accessory kits for setup.

Firmness is adjusted mainly by changing the water volume (some listings recommend filling to about 70%–80%). On certain designs you can also add or release air via valves to fine‑tune firmness in separate chambers.

Freestanding bags use large fillable bases loaded with water or sand (examples note capacities like 100 lb water or 110 lb sand), suction cups on the base, and internal shock‑absorbing springs or dampers to stay stable during use.
