SIZE MATTERS. The largest ever recorded Blue Whale measured 108 feet (33 meters) in length! Typical adult Blue Whales tend to measure approximately 75-100 feet (22-30 meters).
A FEW OF THE HIP FLEXOR TENDONS. As you might imagine, the âHip Flexorsâ are muscles that flex your hips. Flexion of the hip is easy to understand. If you bring your knee toward your chest, you are flexing your hip.
The hip flexors are made up of three different muscles. The Rectus Femoris, Psoas Major, and Illiacus. These muscles work together to help flex the hip, and to provide stability for the lower extremity. The Rectus Femoris is one of the quadriceps muscles, and also helps with knee extension.
