How can I effectively carry 3 suitcases at once without straining myself?

To effectively carry 3 suitcases at once without straining yourself, use a luggage cart or trolley to distribute the weight evenly. Alternatively, consider using a backpack for one suitcase and carrying the other two in each hand to balance the load. Be sure to lift with your legs, not your back, and take breaks if needed to avoid overexertion.
