Take Care of Your Lats

latissimus dorsiIf you’ve ever rowed a boat, done a pull-up, or deadlifted weight, you’ve probably felt the effects in your lats. Your Latissimus dorsi (lats) are the broadest of the main muscles in your back and are located in your mid/lower back.

The muscle is responsible for extension (rowing, swinging your arms as you walk), adduction (pull-ups, chin-ups, or lifting a heavy object from a shelf above your head) and rotates the arm toward the body’s midline (like when you fold your arms over your chest) and serves a minor role in assisting other muscles.

While your lats perform important functions, they also are largely responsible for holding the shape and contours of your midsection and chest. Developed lats make for a trimmer appearance.

For those into anatomy, here’s the official scoop on the lats:

Please, Tell Me About Knees!

Your knees are among the largest joints in your body and are under intense weight-bearing strain and used daily–no wonder they hurt sometimes.

The knee joint joins your thigh bone (femur) and your shin bone (tibia). The fibula bone runs alongside the tibia and, along with the kneecap (patella), make up the rest of the bones in the knee. Two c-shaped pieces of cartilage, the medial and lateral menisci, act as shock absorbers between femur and tibia.

The knee joint is the most complex in the body.  It’s a “condylar” joint, meaning it has two protrusions on the femur (called condyles) and the the tibia has two grooves which enable them to roll and slide against each others. Because of it’s unique structure, it’s also a hinge joint.
