The Seated Barbell French Press is an isolation exercise that emphasizes the triceps, particularly the long head. Sit on a bench with back support, holding a barbell with a narrow grip above your head. Slowly lower the bar behind your head by bending at the elbows, then extend back to the starting position with control. This movement improves tricep strength, definition, and endurance while maintaining proper elbow and shoulder alignment for safe, effective training.
