Most people require around 20 calories per pound (or 44 kcal / kg) of bodyweight to gain muscle mass. Using a 180-pound (82kg) male as an example, the required daily calorie intake is 3600 calories (20 kcal x 180 lb = 3600 kcal). When it comes to gaining weight, it is likely that you may put on a few pounds of fat along the way, but if you do find your body fat increasing, either increase the amount of aerobic exercise (moderate intensity) you are doing or slightly reduce the total number of calories you are consuming. Remember you can’t force feed muscle gain!

But how do you actually know if you have weak glutes? A good way to test them is to do a single leg squat as low as you can go, says Brian Schulz, MD, an orthopedic surgeon and sports medicine specialist at Kerlan-Jobe Orthopaedic Clinic in Los Angeles, CA. “Knee flexion to 90 degrees is a good sign that the gluteal muscles are strong enough,” he says.
Your standard lunge does a nice job of making your derriere stronger, but to get glutes that function at their best, you need to start moving sideways, too. You see, when you do a side lunge or skaters, for example, you strengthen muscles in your outer hips. And strong outer hips can help you steer clear knee injuries. Plus, the sideways moves engage glute muscles so they can reap all the benefits of lower-body exercises. Not sure where to start? These exercises will help inspire you to work your glutes at a new angle.
Stand on your right foot and lift your left foot off the ground. Inhale as you step your left foot backward into a lunge, so that your left knee hovers above the ground. Exhale as you drive through your right heel to rise to a single-leg stance, bringing your left leg forward and up to hip height. Do 10-12 reps. Switch sides. Optional: Load this move by holding a kettlebell at your chest or a dumbbell in each hand. 

Most folks work a 9 to 5 position but if you’re not in the corporate world yet then odds are you’re a student with classes scattered throughout the day and it takes up the vast portion of your free time. That being said, you’re likely going to have to work out in the morning or the evening in order to fit in your session amidst the hectic commitments in your everyday life. Here are a few things to consider in regards to each time period:

The motor proteins actin and myosin generate the forces exerted by contracting muscles. Current recommendations suggest that bodybuilders should consume 25–30% of protein per total calorie intake to further their goal of maintaining and improving their body composition.[30] This is a widely debated topic, with many arguing that 1 gram of protein per pound of body weight per day is ideal, some suggesting that less is sufficient, while others recommending 1.5, 2, or more.[31] It is believed that protein needs to be consumed frequently throughout the day, especially during/after a workout, and before sleep.[32] There is also some debate concerning the best type of protein to take. Chicken, turkey, beef, pork, fish, eggs and dairy foods are high in protein, as are some nuts, seeds, beans, and lentils. Casein or whey are often used to supplement the diet with additional protein. Whey protein is the type of protein contained in many popular brands of protein supplements and is preferred by many bodybuilders because of its high Biological Value (BV) and quick absorption rates. Whey protein also has a bigger effect than casein on insulin levels, triggering about double the amount of insulin release.[33] That effect is somewhat overcome by combining casein and whey. Bodybuilders are usually thought to require protein with a higher BV than that of soy, which is additionally avoided due to its claimed estrogenic properties. Still, some nutrition experts believe that soy, flax seeds and many other plants that contain the weak estrogen-like compounds or phytoestrogens, can be used beneficially, as phytoestrogens compete with estrogens for receptor sites in the male body and can block its actions. This can also include some inhibition of pituitary functions while stimulating the P450 system (the system that eliminates hormones, drugs and metabolic waste product from the body) in the liver to more actively process and excrete excess estrogen.[34][35] Cortisol decreases amino acid uptake by muscle, and inhibits protein synthesis.[36]
In case you weren't aware, your butt is pretty amazing. It helps your body stay upright, enables you to power through workouts, and looks fantastic when squeezed into a pair of skinny jeans, just sayin'. That's why it's so important for you to know how to get the most out of your glutes, the muscles in your posterior. Read on for all the crazy details.

Don’t take sets to the point of failure—where you absolutely can’t perform another rep. You should never get to where you’re turning purple and screaming like you’re getting interviewed by “Mean” Gene Okerlund before WrestleMania. Most of the time, you want to end your sets two reps before total failure. Not sure when that is? The moment your form breaks down, or you’re pretty sure it’s going to break down, end the set.

But, what about fats? Well, our body fat is the home for fats. Whatever fats not used for energy will be stored as fat. That’s the point of fat. This doesn’t mean fats make us fat, sure fats lead to direct fat gain, but this doesn’t mean weight gain. Fat vs weight gain is different. Fat gain can only lead to weight gain if you eat in a calorie surplus. Even if carbs to stored as fat, if you aren’t in a surplus…this fat will be used, so it doesn’t matter this is got stored as fat. Just stop filling up your glycogen levels unless you are always depleting then. Same with fats, just because they increase fat doesn’t mean they make us fat. INCREASED FAT VS INCREASED WEIGHT is different. If we eat fat we store fat. If we eat carbs we store carbs. If we store fat, that fat will only remain their and contribute to weight gain IF it’s not used for energy. If it’s used for energy then we are in a deficit unless we eat out way back to a surplus.
Too much sitting: You probably know it can contribute to serious health problems like obesity and osteoporosis. But did you know it also contributes significantly to back woes, including lower back pain in yoga poses? Fortunately, you can use your yoga practice to offset the effects of a sedentary lifestyle, relieve associated back pain, and set the stage for safe practice of intermediate poses like backbends.

The volume here isn’t excessive. You’ll do 11 sets total for large muscle groups (the one exception being shoulders, for which you’ll do 15) and train each bodypart once a week. Reason being, to pack on tons of mass you need ample recovery time. Doing endless sets in each workout can easily put you in a catabolic (muscle-wasting) state in which lean tissue is broken down, not built up. Gaining 10 pounds of muscle in such a short period requires the right balance of adequate volume to rest and recovery.

  Take note to see if the thigh rests down parallel to the ground (Picture 2) or if it stays up in the air (Picture 1) (You will need someone to be nearby to see what your leg does). Perform on both sides and compare. If the thigh does not stay raised up in the air then there is no true hip flexor tightness and stretching does not need to be performed. If one of the thigh/legs stays up noticeably higher than the other, then stretching will need to be performed. If your leg is able to hang down comfortably parallel to the ground or lower then you passed the test!
To avoid hip flexor pain, you should pay more attention to these muscles, Dr. Siegrist explains. When you are seated, your knees are bent and your hip muscles are flexed and often tighten up or become shortened. “Because we spend so much of our time in a seated position with the hip flexed, the hip flexor has the potential to shorten up. Then, when you are in a hurry because you are running to catch a bus or a plane, or you trip and fall, the muscle could become stretched. Here’s this stiff, brittle muscle that all of a sudden gets extended, and you could set yourself up for strain or some hip flexor pain.”
A: Start with the calculations above but don’t be afraid to adjust up or down. Your metabolism and physiology will adapt to more food by trying to maintain homeostasis and regulate your bodyweight. Some may have to increase more than others but the number on the scale doesn’t lie. If it’s not going up, then you probably need to increase your calories.
If you're 12 weeks out from a competition, you want to maintain as much muscle as possible while torching fat from every angle. This means low-intensity cardio – high intensity cardio speeds up your metabolism and burns fat very quickly, so you run the risk of burning muscle too, Terry says – either first thing in the morning on an empty stomach, or immediately after your weights session, once you’ve depleted those glycogen levels.
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]
(6) “Needs to go somewhere” This is where I explain the end of point 3. Insulin is not a fat storage hormone. Insulin simply transports, nutrients, into cells for energy and then stores the nutrients. Protein is not stored, they are recycled, this is why it’s wise to be consistent with protein. Fats are stored as fat. Carbs are stored as glycogen. IF GLYCOGEN is full then insulin will transport the excess glucose to body fat as the glucose needs to go somewhere. It’s not just gonna sit in the blood. If so, this calls for chaos. People that are insulin resistant usually have this chaotic issue.
How many calories your metabolism needs in order for one to stay the same weight will depend on ones weight as mostly everyone weighs a different number (and some the same). People that weigh more will have a higher metabolism because their body requires more food then if someone that weighed less. People that weigh less will have a lower metabolism because their body doesn’t need as many calories compared to someone weighing more.
And not to drop a truth bomb but, most of us need to be doing glute exercises — and aren’t. “Lack of use is the biggest reason so many people tend to have weak glutes,” says Cassandra York, PhD, MS, RD, CSCS, best-selling fitness author and a professor at Central Connecticut State University. “We don’t walk as much as we used to. We don’t take the stairs. And when we do move, we tend to be quad dominant,” says York.
In addition to adequate protein, you need more calories (your protein intake contributes to your total caloric intake, so these two go hand in hand). Use the following formula to calculate the number you need to take in daily to gain one pound a week, and break down your diet using the macro guidelines listed above. (Give yourself two weeks for results to show up on the scale. If you haven't gained by then, increase your calories by 500 a day.)

By that logic, a 160-pound man should consume around 160 grams of protein a day—the amount he'd get from an 8-ounce chicken breast, 1 cup of cottage cheese, a roast-beef sandwich, two eggs, a glass of milk, and 2 ounces of peanuts.) If you don't eat meat for ethical or religious reasons, don't worry — you can count on other sources, too. Soy, almonds, lentils, spinach, peas, and beans are packed with protein.

Other muscles that can be recruited to assist with hip flexion include the tensor fascia latae (TFL), the pectineus, the adductors, the gracilis, and the anterior aspects of the gluteus medius and the gluteus minimus. The contribution of these secondary hip flexors largely depends on the position of the hip at the time at which movement is initiated.
Longer rest periods are more ideal for making progressive tension overload happen, and shorter rest periods are more ideal for generating metabolic fatigue. So, if you’re doing an exercise that is better suited for progressive overload (i.e. primary compound exercises), you’re going to want to rest longer between sets to maximize strength output. And if you’re doing an exercise that is better suited for metabolic fatigue (i.e. isolation exercises), you’re going to want to rest less between sets to make that happen. And if you’re doing an exercise that is suited equally for a combination of the two (i.e. secondary compound exercises), you’re usually going to want a moderate rest period somewhere in between.
If you tend to stand with a "swayback," developing awareness of the opening at the front of your hips is especially important. In Tadasana (Mountain Pose), practice lifting the ASISes, moving the tailbone down, and lifting the lumbar spine. Putting a belt around your waist, as you did in Warrior I, may help you increase your awareness of your pelvic alignment in this pose too.
Sure, using a more effective workout routine or diet plan will work better/faster than a less effective one. However, even when you’re doing everything just right and you’ve optimized every single major and minor factor to work as quickly and effectively as possible (which I’m going to show you how to do), the simple fact is that you’re still not going to build muscle “fast.”
Eating the right carbs is important too. Carbohydrate is stored in your body in the form of glycogen. Glycogen in the muscles is an important fuel reserve during intense physical exercise or in times of energy restriction – protein sparing. It is best to restrict or to keep away from junk carbohydrates such as sweets, cakes, and biscuits, and stick to foods like porridge, pasta (wholemeal), rice (brown), bread (wholegrain), and cereals (try to choose the versions with low or reduced sugar and salt).

How to do it: Lie on your back with both feet planted firmly against the flat base of a Bosu ball, knees bent. Stabilize your body. If you’re feeling a bit wobbly, your arms can hover on either side of you in case you fall in one direction. If you feel balanced, raise your arms straight up above your chest, hands clasped to challenge and work your stability. Drive your hips toward the ceiling, then lower and repeat.
