For studio fitness classes or to supplement home workouts, our preloaded barbell sets are perfect for building strength or working up a sweat. Featuring a barbell, rubber plates and quick release collars, our barbell sets offer great variety for training in class settings. The quick release collars enable weights to be changed in a flash, great for circuits and HIIT. Studio barbells are made from rubber or urethane, meaning no damage to home and studio floors with use.
