Using these York dumbbells is easy. You can do a variety of exercises like bicep curls for your arms, shoulder presses for your shoulders, and lunges with the dumbbells for your legs. When using them, make sure to hold them firmly to avoid any accidents. Also, start with a lower weight if you're a beginner and gradually increase it as your strength improves. For maintenance, keep them in a dry place to prevent rusting. Wipe them with a clean cloth after each use. Remember, since they are oversized, they can't be sent to rural or overseas areas.
