One of the sleeves supports a fixed hanger and the other sleeve supports a swing-bar which can rotate through 360.degree. and carries a handle. A brake increases the resistance of the apparatus to the user, said resistance being already adjusted by resilient elements placed between the fixed hanger and the swing-bar.
