ABSTRACT:
A resistance-type exerciser has pivotally interconnected arms with a more closely spaced pair of handle forming ends and a less closely spaced pair of handle forming ends. A caliper-type spring unit is replaceably fitted to the arms to urge the less closely spaced pair of ends apart. The spring unit can be readily replaced with another unit of different spring pressure so as to vary the resistance of the exerciser. The exerciser is used by pushing the less closely spaced ends toward one another against the spring pressure or by pulling the more closely spaced ends apart.
