Performing biceps curls in different positions surely ads to the intensity of your workout. This shallow-end exercise requires aqua dumbbells or any water resistance device for better results. If you have none, use the inside of your hand to create more resistance as you push the water in front and down.
Stand in the shallow-end. Bend one leg in front and stretch your other behind. Put your shoulders in the water and hold the dumbbells with your arms spread out, wide. Let your palms face forward.
With your shoulders still, bend your elbows toward your torso bringing both dumbbells closer to each other. Extend again, twist your arms to let your palms face downward, then repeat the same by bending your arms as deep as you can. Always keep your shoulders still as you bend and stretch your arms all the way out.
Focus on using your biceps with each arm bend. Feel your triceps too as you extend your arms on your torso level. Extending your arms up does not create resistance if you are using floating dumbbells.
Inhale as you extend your arms and exhale as you bend. Don't bend your arms too fast and focus on good breathing.
