Final answer:
To prevent straining your back, it is important to use proper lifting technique and lift with your leg muscles instead of your back. Squatting down and keeping your back straight while engaging your leg muscles helps distribute the weight more evenly and reduces the strain on your back.
Step-by-step explanation:
The type of cut that helps prevent straining your back is to bend your knees and lift with your leg muscles, rather than bending at the waist and using your back muscles. This technique is known as proper lifting technique and it helps distribute the weight of the object being lifted more evenly throughout your body, reducing the strain on your back.
For example, when picking up a heavy box from the floor, you should squat down, keeping your back straight, and use the strength of your leg muscles to lift the box. By keeping your back in a neutral position and engaging your leg muscles, you can prevent straining your back and minimize the risk of injury.
