Which are the strongest muscles?
Although it is not very big, the strongest muscle in the body, for its weight, is the masseter muscle in the jaw. It allows you to have a powerful biting action. The largest muscle of all is the gluteus maximus (a Latin name, like many medical terms). It runs from the buttocks down the back of the thigh. The longest muscle is the sartorius, which runs from the hip bone, or pelvis, right down to just below the knee.
What is muscle tone?
Muscles need constant work to keep them strong and healthy. When two muscles work against each other, they will always be slightly contracted and under tension. This is called muscle tone. The fitter you are, more strongly these muscles will pull against one another, even while you are relaxed.
