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 (psoas) are the most important muscle for hip flexion (moving your leg forward). The most important muscle for extending your hip (moving your leg back) is the gluteus maximus. Both of these muscles obviously attach high on the hip and control the femur bone (upper thigh).
