Do any of you guys that lift at home use olympic dumbbell’s? and if so what type of collars do you use? I have been using the spring collars and they seem to allow to much movement of the plates.
Bulldog collars from ironmimd
Pricey but they lock on tight. Good for bench and overhead work. The spings are sloppy but are fine for me for db rows and similar type work.the bulldogs lock on TIGHT. Not great if you want to change weight every set.
