Up-to-date training facilities are developed which are able to control loading in order to adapt to the trainee physical abilities, the aim of exercises and make the loading as close as possible to specific sports movements. The arm exercising is simple and effective, thus widely used in practice. Its disadvantage is instability of the arm loading due to inertia forces acting on the lifted mass and changing the arm geometry when exercising. The paper deals with the analysis of possibilities to control the law of loading during the exercising cycle by means of magnetorheological fluid damper.
