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 calf is actually two muscles: the gastrocnemius, and the deeper muscle, soleus. Both of these muscles insert into the Achilles tendon at the back of the ankle. The calf, because of the configuration of the ankle and relatively long lever arm is a very powerful plantar flexor.
