Which of the following is considered a bad habit to monitor in order to avoid repetitive motion problems?

Gripping tools too tightly is recognized as a bad habit because it can lead to undue stress and strain on the muscles and tendons in the hands and wrists. This excessive tightness can increase the risk of developing repetitive motion injuries, such as carpal tunnel syndrome and tendinitis, which are often caused by the cumulative effects of stress on the musculoskeletal system. It's important to use tools with a relaxed grip, as this can help minimize fatigue and prevent these types of injuries.

In contrast, using ergonomic tools, maintaining a straight back, and taking regular breaks are all positive practices that promote good posture and reduce the risk of injury. Ergonomic tools are designed to fit the natural position of the body, supporting better alignment and reducing strain. Keeping a straight back helps maintain proper posture, which is crucial for overall body health. Additionally, taking regular breaks allows the body to rest and recover from repetitive tasks, significantly mitigating the potential for injury.
