A functional capacity evaluator has a strain block and a strain gauge attached to the strain block. A first pair of grips is attachable to the strain block such that when a user squeezes them together using a grip motion, the strain block and strain gauge are flexed for measuring the users grip strength. A second pair of grips is attachable to the strain block such that when the user squeezes them together using a pinch motion, the strain block and strain gauge are flexed for measuring pinch strength. A deadlift bar is attachable to the strain block such that when the strain block is supported in a first direction and the user pulls on the bar in an opposing direction, the strain block and strain gauge are flexed for measuring deadlift strength.
