CalGym CG-7508 Selectorized Seated Tricep Extension Machine - The CalGym CG-7508 by TuffStuff is a selectorized tricep extension machine that allows the user to isolate the tricep muscles similar to performing lying tricep hammer extensions with dumbbells and a flat utility bench. Using the neutral grips, train the outer and mid heads of the triceps by keeping the elbows in close throughout the exercise and to hit the inner head bring the elbows slightly out. The pivoting handle and biomechanically engineered cam drive system work together with the body to provide an effective tricep workout with minimal stress on the joints. Providing the resistance to the user is a 150 lb. weight stack that is adjustable in 10 lb. increments via a magnetic selector pin. Users of all heights can customize the fit of the CG-7508 thanks to the adjustable thigh rollers and telescoping seat. The seat also includes a secondary pad in the back to prevent the user from sliding while performing heavy tricep extensions. All padding consists of dense urethane foam padding backed by 3/4” plywood to withstand the harshest workouts.

The CalGym selectorized tricep hammer extension machine offers exceptional value and performance and is ideal for use in school weight rooms, fitness training studios, apartment building gyms and corporate wellness facilities. Each selectorized strength training machine offers commercial grade components throughout including heavy-duty 2” x 4” x 11 gauge oval steel tubing with platinum sparkle powder coat finish, 3/4” solid steel guide rods and protective weight stack shrouds with exercise placards.
