Resistance band seated biceps curl

Sit on a chair or bench with your back straight and feet flat on the ground. Hold the resistance band with an underhand grip, palms facing up, and arms extended down by your sides. Keeping your upper arms stationary, exhale and curl the resistance band up towards your shoulders. Pause for a moment at the top, squeezing your biceps. Inhale and slowly lower the resistance band back to the starting position. Repeat for the desired number of repetitions.
