Targeting the larger muscles???

hamstrings are definatly one of the largest, walking/jogging/skipping ect can tone your hamstrings

I find conflicting information but I've read before that the back is the largest. I found the below information using Yahoo.

The largest muscle is actually the latissimus dorsi(back muscle),the gluteus maximus is the strongest muscle.longest muscle is the sartorius and as everyone has said the skin is actually an organ and not a muscle.the skin s the largest organ in the human body.

The gluteus maximus or buttock muscle is the biggest of the 639 named muscles in the human body.

The longest muscle in the human body is the sartorius. This narrow muscle of the thigh passes obliquely across the front of the thigh and helps rotate the leg to the position assumed in sitting cross-legged. Its name is a derivation of the adjective "sartorial," a reference to what was the traditional cross-legged position of tailors (or "sartors") at work.

The Body's Bulkiest Muscle

The biggest (bulkiest) of the skeletal muscles is the Gluteus maximus - the buttock muscle. It is a very superficial and prominent muscle. In humans it is bigger than that of chimpanzees and gorillas. There are three major muscles in the buttock: the Gluteus maximus, medius and minimus.

The Gluteus maximus has an origin in the iliac crest (the hip bones upper margin) as well as from the sacrum (the triangular bone forming the hip girdle). The Gluteus maximus is inserted into the femur, or thigh bone. The job of the Gluteus maximus is to move the thigh away from body in median line. It also rotates the thigh laterally, or sideways.

The Muscle With the Most Surface Area

The muscle with largest surface area is the latissimus dorsi, the broad muscle that covers the middle portion of the back. The word 'latissimus' itself means 'widest'. It originates from the last six thoracic vertebrae, lumbar vertebrae and last four ribs. It is inserted into the arm bone humerus with a tendon about 7 cm (slightly less than 3 in) long.

It helps in moving the arm toward the central axis of the body and also in arm rotation. Our shoulders can be drawn backwards and downwards with this muscle. It also helps in forced expiration in violent breathing movements, such as coughing or sneezing

The Longest Muscle

The body's longest muscle is the sartorius. It is a strap-like, narrow muscle which runs from the hip to the knee. It has its origin in upper part of ilium, the ear-shaped hip bone, and is inserted into the tibia, the broad, strong bone of the shank. The insertion resembles a flattened tendon. The sartorius moves our leg nearer the body in midline and helps to rotate and cross the leg.
