We know you're tough, but overexerting yourself and ending up in the emergency room doesn't help your tough-guy (or tough-girl) image.
Lifting 10 pounds doesn't sound like much, but do it wrong and you could be putting more than 1,100 pounds of pressure on your lower back!
Overexertion injuries typically result in strains or sprains to the muscles, tendons or ligaments. Lifting heavy loads or lifting incorrectly
are examples of overexertion, but there are others. Ergonomics - the design of a workplace to help people work more efficiently and safely -
plays an important factor. How you sit and how you move can cause fatigue and/or impact musculoskeletal health. Big word, but think
"muscle and skeleton," and you'll get the idea. Even using the wrong tool or poorly-maintained tools can hurt by requiring you to
use awkward motions or more force than necessary.
