For a calf-specific workout the Impulse IT rotary calf is a great choice. The machine is strong & will withstand heavy use & has been designed to be easy to use, with upholstery that can be wiped clean afterwards. The seat back is adjustable & the 91kg (200lbs) weight stack is covered by a protective screen for your safety. The hand grips allow users to control repetitions better & stabilise themselves during exercise.
