An over-torque resistant vial and closure assembly includes a vial having an outwardly projecting rib that cooperates with a stop surface provided on a closure. When the closure is threadably coupled to the vial, the stop surface of the closure engages the outwardly projecting rib of the vial so as to prevent over-torquing of the closure onto the vial.

A plural parallel cuff for muscle training is made to reinforce muscles of limbs while it is wound broad around the portion of an upper arm and/or a thigh with uniform and stable binding force for the light exercise training. Three cloth sleeve bags are sewn to a connection cloth spaced in parallel. Three short rubber bags are inserted into three cloth sleeve bags respectively. The rubber bags are connected each other with T-joints for air channel. A plug and a socket are used to connect the pneumatic pump detachably to the thin tube. The plural parallel cuff is wound around a limb and hook-and-loop fasteners are used to form loops by uniting both ends of each of the cloth sleeve bags. The rubber bags are inflated by a pneumatic pump for restricting the bloodstream and then an low intensity exercise is performed.
