Performing the: A Step-by-Step Tutorial Smith Machine Bicep Curl
Stand facing the machine, feet shoulder-width apart, and grab the bar with an underhand grip (palms facing up), hands shoulder-width apart.
With your elbows close to your torso, curl the bar towards your chest by bending your elbows, while keeping your upper arms stationary.
Hold the position for a moment when your biceps are fully contracted and the bar is at shoulder level.
Slowly lower the bar back to the starting position, fully extending your arms and stretching the biceps, and repeat for the desired number of repetitions.
