TuffStuff’s Proformance Plus Biceps / Triceps (PPD-804) features a counter-balanced pivot arm with multi-grip handles that allow overhand and underhand grip positions.  The pivot arm on the Proformance Plus Biceps / Triceps is counterbalanced for true starting resistance, and adjusts with a pop pin to enable quick transitions between biceps curls and triceps extension exercises.  The arm pad is ergonomically designed to fit snugly when the gas-assisted seat is adjusted to the proper height. This ensures proper support and comfort for both curling and triceps presses.  As an added bonus, because the multi-grip handles are designed for overhand and underhand grip exercises, users can comfortably perform reverse curls to target their forearms as well.
