Your Tendency: To start your cooking marathon by clearing off the counter and quickly starting to chop. But be aware that a counter that is too high or too low for your height can force you to hunch over, straining the muscles in your neck, shoulders, and lower back.

The Better Way: To check the height of the counter before you slice and dice. Put your arms at your sides and bend your elbows to 90 degrees. The surface should be no more than a few inches below your hands. If it’s too low, stack cutting boards; if it’s too high, stand on a sturdy stool. To lessen back strain, stand with your feet shoulder-width apart, shoulders back, and knees soft.
