In other primates, gluteus maximus consists of ischiofemoralis, a small muscle that corresponds to the human gluteus maximus and originates from the ilium and the sacroiliac ligament, and gluteus maximus proprius, a large muscle that extends from the ischial tuberosity to a relatively more distant insertion on the femur. In adapting to bipedal gait, reorganization of the attachment of the muscle as well as the moment arm was required.[4]
The good news is that there are plenty of good hip stretches out there that you can do to relieve discomfort, decrease tightness, and increase mobility in your hips. Since your hips are involved in so many of the movements you make (both inside and outside of the gym) stretching them is a great way to keep them feeling good and ready to work for you. Add some of the 12 hip stretches Atkins demos below to the end of your workout, or spend 10 minutes each day just doing a few of them, to improve mobility in your hips.
The hip flexors help balance the posterior pelvic muscles. Three key muscles often become tight and shortened as a result of activities of daily living. These are the iliacus, psoas major, and the rectus femoris. The iliacus and the psoas major are often referred to as the iliopsoas because they share the same insertion at the lesser trochanter of the femur. The psoas minor inserts on the superior ramus of the pubis bone and mainly supports the natural lordotic curvature of the spine, but is only found in about 40% of the population. The psoas major originates on the anterior surface of the lumbar vertebrae and runs over the pubis bone and inserts into the lesser trochanter of the femur. This muscle not only helps to flex the hip, but also has an effect on the lordotic curvature of the lumbar vertebrae. The rectus femoris has a proximal attachment at the acetabulum and inserts into the tibial tuberosity. This long muscle plays a role in both hip flexion and leg extension (Figure 9-4).
How to do it: Start by stepping forward into a lunge with your left foot. Place your right forearm to the ground and your left elbow to the inside of your left foot, and hold the stretch for two seconds. Then place your left hand outside of your foot and push your hips up, pointing your front toes up. Return to standing position and repeat by stepping out with your right foot. Continue alternating sides.
Manipulating carbs is one thing, but dealing with fats is another. Bigger people already have enough fat, they don’t need to eat fat. They don’t need keto. Skinny people don’t have much fat, which means they should eat it. Doing Keto is helpful. BUT, skinny people fasting during Keto is nonsense because they don’t have enough fat to sustain a fast. Bigger people don’t need to worry about fasting during Keto because they shouldn’t even be doing Keto.

There are nutrients within these fat sources which decrease inflammation, improve mental function, improve eyesight, and give you healthier skin, hair, and nails. When I'm crushing the iron in the gym each day, my goal is to be strong and big, but also healthy and mobile. To get that way, I eat all of these generously on a regular basis, and I also take omega-3 supplements daily, in the form of fish oil or krill oil.
