How can a waiter reduce the risk of back strain when placing item on the table?

A waiter can reduce the risk of back strain by using proper lifting techniques, such as bending at the knees rather than the waist when reaching for items. They should also keep their load close to their body to minimize strain on the back and use smooth, controlled movements while serving. Additionally, arranging items strategically on trays can help distribute weight evenly and reduce awkward bending or twisting. Regular breaks and stretching can further help maintain back health during long shifts.
