Bicep & Tricep Machines

Get on the gun show and pump up your biceps and triceps. These two muscle groups are antagonists, meaning they work together with opposing movements. When you contract the biceps the triceps will relax and lengthen, and vice versa. So don’t ignore the triceps, both are equally important and the triceps are the bigger of the upper arm muscles, potentially accounting for 70% of an arms total mass, making it the best muscle for filling out shirt sleeves. Various seated positions on these bicep and tricep machines offer a range of benefits for isolating these important upper arm muscles, while supporting your back and chest for maximum gain.
