The sartorius originates at the ASIS and proceeds to traverse obliquely and laterally down the thigh to eventually insert at the anterior surface of the tibia, just inferomedial to the tibial tuberosity, as part of the pes anserinus. In addition to flexing the hip and knee, the sartorius aids in the abduction of the hip. It is innervated by the femoral nerve (i.e., the posterior division of L2 and L3).
A: At the end of the day, the most important variable regarding weight gain or loss is calorie consumption. However, meal frequency and timing around activity can both influence workout intensity and duration thus potentially allowing for further improvements in body composition. Remember, muscle growth isn’t a pulsatile process, it doesn’t just acutely spike and then return to baseline so if there aren’t circulating amino acids within the blood stream then they’ll have to be broken down from muscle as this is the highest form of concentrated amino acids within the body. That being said, it would probably be a good idea to consume anywhere from 3-6 meals spread throughout the day depending upon your schedule and preference. Ideally, we want to stimulate anabolism through food every 3-5 hours.

When it comes to building muscle, your body only knows or cares about the tension, fatigue and damage an exercise is generating… not the type of equipment you were using when performing that exercise. It really couldn’t give the slightest crap about that. For this reason, ALL types of exercises and ALL types of equipment are capable of stimulating muscle growth.
Bodybuilders often split their food intake for the day into 5 to 7 meals of roughly equal nutritional content and attempt to eat at regular intervals (e.g. every 2 to 3 hours). This method can serve two purposes: to limit overindulging in the cutting phase, and to physically allow for the consumption of large volumes of food during the bulking phase. Contrary to popular belief, eating more frequently does not increase basal metabolic rate when compared to the traditional 3 meals a day. While food does have a metabolic cost to digest, absorb, and store, called the thermic effect of food, it depends on the quantity and type of food, not how the food is spread across the meals of the day. Well-controlled studies using whole-body calorimetry and doubly labeled water have demonstrated that there is no metabolic advantage to eating more frequently.[38][39][40]
Elsa Pataky's trainer, Fernando Sartorius, says that focusing on squeezing your glutes while performing a booty-blasting exercise allows you to activate the muscle group to their maximum potential. Cameron Diaz's trainer, Teddy Bass, founder of the trademarked booty-sculpting program called Rock Bottom Body, says you should get into a bridge position and memorize what it feels like to really engage your buns—and then try to feel that burn every time you work your butt. The point: Thinking about squeezing your glutes (and actually squeezing them) while strength-training helps you work the muscles in your butt harder.
Choosing the right size stability ball matters—if you’re using one that’s too big or small, your body positioning could be wonky, making the move less effective, says Henwood. For the V-Lift and Bulgarian Split Squat in this workout, choose a ball that naturally has your legs at a 90-degree angle when you sit on it (your hips should be at the same height as your knees). You may need a smaller option for the Hamstring Press—opt for one that you can comfortably hold between your legs so it stays put for every rep.
Notice when we are scared or exited that we start to breathe faster. Adrenaline causes this. Which means to calm ourselves we must not breathe fast, we just breathe slower. The slower we can breathe the less stressed we will feel. The slower we can breathe the longer our strokes will be. When we breathe fast, our strokes (breathing in and out) becomes shortened. When we breathe slower we can engage the diaphragm in a way to eventual allow us to breathe longer strokes.

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]

In today's extra-large society, we tend to focus on the admirable guys who train hard and switch up their diet to transform their bodies by losing weight. We highlight their quests to lead healthier lives every chance we get — but there's another side of the wellness scale that can be just as difficult, depending on your body's makeup: Gaining mass and muscle.
In the 1970s, bodybuilding had major publicity thanks to the appearance of Arnold Schwarzenegger, Franco Columbu, Lou Ferrigno, and others in the 1977 docudrama Pumping Iron. By this time, the IFBB dominated the competitive bodybuilding landscape and the Amateur Athletic Union (AAU) took a back seat. The National Physique Committee (NPC) was formed in 1981 by Jim Manion,[7] who had just stepped down as chairman of the AAU Physique Committee. The NPC has gone on to become the most successful bodybuilding organization in America and is the amateur division of the IFBB. The late 1980s and early 1990s saw the decline of AAU-sponsored bodybuilding contests. In 1999, the AAU voted to discontinue its bodybuilding events.
Work on strengthening all of your core muscles and glutes. These muscles work together to give you balance and stability and to help you move through the activities involved in daily living, as well as exercise and sports. When one set of these muscles is weak or tight, it can cause injury or pain in another, so make sure you pay equal attention to all of them.
Your hip flexors are the muscles that comprise the front of your hip; you use them when you bend your hip, run or kick. Your hip flexors are susceptible to pain or injury if you place excessive or repetitive stress on them. Hip flexor pain is often the result of strains that occur when your hip flexor muscles sustain tears. Tight muscles, a direct blow to your hip or poor conditioning can lead to a hip flexor strain. While hip flexor pain should be examined by a physician, there are actions you can take to help get rid of hip flexor pain.
The iliopsoas is another powerful hip flexor that begins in two distinct regions proximally. The iliacus has a broad origin, arising from the inner table of the iliac wing, the sacral alae, and the iliolumbar and sacroiliac ligaments. The psoas originates at the lumbar transverse processes, the intervertebral discs, and the adjacent bodies from T12 to L5, in addition to the tendinous arches between these points. Distally, the two large muscular bodies converge to become one distinct structure—the iliopsoas—and subsequently jointly insert at the lesser trochanter of the proximal femur. The nerve to the iliopsoas (i.e., the anterior division of L1 to L3) supplies the iliopsoas muscle.

Stand tall with your hips square and bend your right knee, bringing your foot towards your bum. Grab the right foot with your right hand and actively pull the foot closer to your glutes. As you do this, send the right knee down towards the ground and keep both knees together. squeeze your butt to promote a posterior pelvic tilt and hold — then switch sides.
The three players that make up your glutes are the gluteus maximus, gluteus medius, and the gluteus minimus. The maximus is pretty much the M.V.P. It creates the shape of your butt and works anytime you raise your thigh to the side, rotate your leg, or thrust your hips forward. The other two, the medius and minimus, work together to aid your gluteus maximus in raising your leg to the side. Plus, those smaller glute muscles help rotate your thigh outwards when your leg is straight, and inwards when your hips are bent. Talk about a dream team! (To learn more about the workings of your glutes, check out The Women's Health Big Book of Exercises!)
From a standing position on your left foot, hinge forward from your hips keeping your back flat and right leg in straight behind it, and core braced. Reach your right hand toward your left foot. Then, engage your glutes and hamstrings on your left leg to drive yourself back up to standing and swing your right knee up and through toward your chest. Stand as tall as possible and hold that end position for 2-3 seconds before repeating. This entire exercise is about “sticking” the knee drive hold at the end, so don’t rush through it. Repeat for required reps, then switch sides.
Although muscle stimulation occurs in the gym (or home gym) when lifting weights, muscle growth occurs afterward during rest periods. Without adequate rest and sleep (6 to 8 hours), muscles do not have an opportunity to recover and grow.[citation needed] Additionally, many athletes find that a daytime nap further increases their body's ability to recover from training and build muscles. Some bodybuilders add a massage at the end of each workout to their routine as a method of recovering.[50]
A good butt workout should target the muscles of the entire glute complex: the big, power-producing gluteus maximus, and the smaller, stabilizing gluteus medius and minimus. Below, York, Jones, and award-winning personal trainer Katie Gould share 13 effective butt exercises you can do at home with minimal equipment. All you need for these glute exercises is a flat resistance band/mini band and a kettlebell.
I always recommend starting on the low end of the scale. Only increase volume when you absolutely need to. So, if you’re training chest, you could do 6 work sets of dumbbell bench presses to start out, breaking down to two sets per workout for three sessions per week. You can gradually add sets from there, experimenting with different training splits that will allow you to get in more volume without overtraining (we’ll discuss training splits next).
Learning to activate your glutes is important so that you can strengthen them. Strong glute muscles are extremely important as these muscles can have a major impact on your overall body strength; your glutes support your core, help to support a range of exercises and compound movements, as well as help avoid muscle imbalances which can lead to decreased mobility. 
Creating a workout playlist of high-energy tunes you love will not make your workout feel easier, but it may cause you to exercise harder without even realizing it. Best of all, you need only one or two great tunes to get you through this workout. If you are willing to try something a bit different, make your own music as you exercise. Sing, hum, clap your hands, whatever you can do to jam along to your playlist. It may give you an extra boost to finish strong.

Expert tip: “Optimum form and range of motion for the squat is very dependent on your physicality, structure, joint integrity, limb length, strength, flexibility, and current condition,” Reames says. Your range of motion is 90° max at the knee. Some guys will be able to go lower than this, but not everyone will squat to parallel, he says. And that’s totally okay. “Stick to form and the appropriate resistance levels for you; the squat is still one of the best and simplest moves for overall strength, building lower-body muscle, core strength, and athletic performance. 

Choosing the right size stability ball matters—if you’re using one that’s too big or small, your body positioning could be wonky, making the move less effective, says Henwood.
