FEIERDUN

FEIERDUN is a home strength-equipment brand that now sits within FED Fitness, the master brand that also includes FLYBIRD, YOSUDA, SPORTSROYALS and BCAN. A 2025 FED Fitness press release describes FEIERDUN as a fitness equipment line founded in 1993, while US trademark records show the FEIERDUN mark registered in 2016 to Yiwu Feier Sporting Goods Co., Ltd., a company in Zhejiang province, China. FED Fitness's companion app was previously named Feier, and the former feierfitness.com domain now redirects to the FED Fitness store.

FEIERDUN's range centers on adjustable dumbbells, including 5-in-1 sets with plastic-shelled plates that convert into dumbbells, a barbell, kettlebells and push-up stands, and quick-adjust dumbbells. It also covers bumper plates, a compact rowing machine, vibration plates and machines for leg extensions, calf raises, chest presses and hip thrusts. FED Fitness sells the line on its own website and through online marketplaces such as Amazon.
