Performing the: A Step-by-Step Tutorial Dumbbell Seated Alternate Biceps Curl
Keep your elbows close to your torso at all times, then curl one dumbbell while contracting your biceps, keeping the rest of your body still.
Continue to raise the dumbbell until your biceps are fully contracted and the dumbbell is at shoulder level, while your other hand remains at arm length.
Hold the contracted position for a brief pause as you squeeze your biceps, then slowly begin to bring the dumbbell back to the starting position.
Repeat the process with the other arm, alternating back and forth between each arm for your desired number of repetitions.
