Packing three weights inside of a weighted shell, this kettlebell seamlessly adjusts from 18 lb to 35 lb in seconds, making it the most versatile bell in your weight room. Simply place the side pin in any slot on the shell to adjust it to your desired weight and immediately start lifting at your level. A magnetic pin head keeps weights in place in front rack position and during swings and overhead movements for ultimate safety. A classic contoured bell shape increases comfort for students' forearms and reduces impact during quick reps. Cast-iron construction withstands institutional use and abuse (not intended for gym floors). Includes 18 lb (9 kg) shell and nesting 22 lb (10 kg), 26 lb (12 kg), and 35 lb (16 kg) weights.
