Isolate the inner and outer heads of the bicep muscles with the Muscle D Seated Arm Curl
Also known as a plate-loaded preacher curl bench, the Muscle D Seated Arm Curl is different from your normal free-weight curls as it offers a consistent form of resistance throughout the entire lifting experience through cam-driven movements throughout the entire exercise.
Even the biggest lifters won't have trouble getting enough resistance from the chrome-plated weight horn. The roomy arm pad is made of dense closed-cell foam and is positioned to maximize the resistance strain on the biceps. And it's a breeze to set the seat pad's height thanks to the gas-assist adjustable seat.
