Storage is for anyone whose training space is also a garage, hallway or spare room. Plates, dumbbells and kettlebells need a home or they become the thing you stub a toe on.
Trees start with a 3-tier hex saddle rack or a 3-tier neoprene tree. The Commercial Kettlebell Half Rack is a black two-shelf stand with lips to keep bells from sliding. Horizontal plate racks come standard and extended; there is a 3-tier weight tree with bar holders; the vertical disc-and-dumbbell rack states a 300kg total capacity. Dumbbell-only stands are grouped under dumbbell storage. Free delivery across Great Britain (Scottish Highlands and Islands included) is on every order, heavy storage frames included.
A rack is easier to live with than a pile; the home gym guide puts storage in the build order.
