Meet the Fitfighter Steelhose: a versatile fitness tool that can replace a dumbbell, kettlebell, sandbag, medicine ball, and sledgehammer. You can use these to try lift, swing, drag, and toss movements. They are available from 5 to 50lbs in weight.
The Steelhose has a tough coarse polyester fabric to give you a better grip. They are available in lengths from 18 to 36″. The brass grommets on the ends let you attach these to cable machines.
