TuffStuff’s Proformance Plus Standing Calf (PPS-238) is a full commercial machine for developing calf muscles.  Surprisingly, calf training is frequently overlooked by strength, power, and fitness athletes and coaches.  Many think that isolated calf training is not an effective use of training time.  However, whether walking, running, pulling, or performing nearly any other upright exercise, the first base of support we have with the floor is via the foot and up through the ankle.  “When performing strength and power movements, ankle stability and force production can impact our ability to perform at higher intensities.  Seeing that the standing calf raise can strengthen our ability to plantarflex (place pressure downwards into the floor through the foot), most strength and power athletes will find benefit in growing stronger calves” (read more on barbend).

The Proformance Plus Standing Calf Machine includes high density contoured shoulder pads that seamlessly adjust to accommodate different user heights and ranges of motion.  It comes standard with a 220 lbs. solid steel weight stack and accepts TuffStuff’s patented add-on weight system.  The weight stack may also be upgraded to the optional 295 lbs. stack.  Like all Proformance Plus equipment, the Standing Calf Machine may be customized, and is backed by a 10-year commercial warranty covering the frame, welds, cams, and weight plates.
