1 - Stand with your feet shoulder-width apart, holding a kettlebell in both hands with your palms facing forward. Let your arms hang naturally by your sides.
2 - Keeping your upper arms stationary, exhale as you flex your elbows and curl the kettlebell towards your shoulders.
3 - At the top of the curl, squeeze your biceps for a moment to maximize the contraction.
4 - Inhale as you slowly lower the kettlebell back to the starting position, fully extending your elbows.
5 - Repeat the curling motion for the desired number of repetitions.
