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]
Objective: Are you getting stronger? Increasing either weight or reps? If you're measuring individual markers on a daily basis like vertical jump, grip strength, or resting heart rate then what sort of trends are you noticing in these variables? If they're staying the same while your strength is increasing, then you're recovering well. If they're decreasing and you find yourself weaker over time then you're not recovering well.
The function of the gluteus maximus is primarily upper leg (thigh) extension, such as moving the upper leg backward—think rising from a squat position. Another way of thinking about this is bringing the torso upright after being hinged forward. Think of a kettlebell swing and you’ll get a good visual for the major action of the gluteus maximus muscle.

Stand with your feet at shoulder width and position a heavy kettlebell between your feet. Hinge at your hips and bend your knees while lowering your hands to the kettlebell handle. Your shins should stay vertical. Gripping the handle, exhale as you drive through our heels to extend your hips and rise to standing. Inhale as you slowly lower the kettlebell back toward the ground by hinging at the hips and allowing your knees to bend as needed. Do 10 reps.
We’ve broken down the nine exercises into three sets of three. Before you begin each set, set a timer (or workout near a watch with a second hand.) If you are just starting to work out, do each exercise as hard as you can for one minute, followed by the next, until you complete the first set. Then, take a one minute break before moving on to set two, in which the exercises should also be performed for one minute each. 
The G-med and G-min perform similar functions, depending on the position of the knee and hip joints. With the knee extended, they abduct the thigh (out to the side away from the opposite leg). When running, they stabilize the leg during the single-support phase. With the hips flexed, they internally rotate the thigh. With the hips extended, they externally rotate the thigh.
Beach muscles and Olympic lifts draw more attention. But the many little stabilizer muscles around your shoulders, hips, and midsection — collectively the core — provide a strong foundation. Challenging the stability and mobility of these key muscles with medicine balls, physioballs, mini-bands, and rotational movements (lifting, chopping) pays huge dividends.
(4) Insulin is a fat storage hormone - this isn’t true, okay kinda. Like I mentioned, both insulin and protein trigger insulin. If insulin was the issue than high protein intakes should has a worse reputation beyond what it currently has. Insulin has a job of transporting nutrients into cells. Carbs have a more direct connection to insulin than protein, so when carbs are consumed, insulin is spiked higher. Insulin will take the carbs (sugars) and transport them into cells for energy and then the rest into glycogen to save for later. If glycogen is full, then insulin still has a job to do. It doesn’t just float around dumb founded. It takes the carbs (sugars) and stores then into fat. It’s smart like that. But, we abuse that system by eating too many carbs and being in a surplus. The body doesn’t want to convert carbs into fat, that’s what fats are for, yet we abuse and do it anyways.

As stated before, one of the primary hip flexor muscles is the psoas major. This muscle plays a role in core stabilization (something that is needed during running, squatting, and sitting) due to its attachment site at the spine. If there is a lack of core stability or poor movement patterns during these tasks then the hip flexor can become overworked/tired/fatigued (think what happens when your co workers or teammates don’t do their job, you have to pick up the slack and work harder, bringing you more stress and fatigue). It is when the hip flexor becomes fatigued that the sensation of tightness sets in. This is because the hip flexor has to “work harder” to compensate for other muscles not doing their job.

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 primary hip flexors are the rectus femoris, iliacus, psoas, iliocapsularis, and sartorius muscles. The rectus femoris muscle has two distinct origins proximally: the direct head and the reflected head. They originate at the AIIS and the anterior acetabular rim (in close proximity to the anterior hip capsule), respectively. The tendinous fibers of the rectus femoris coalesce distally and become confluent with the other quadriceps musculature in the thigh. The quadriceps consists of four distinct muscles: 1) the vastus intermedius; 2) the vastus lateralis; 3) the vastus medialis; and 4) the rectus femoris. The rectus femoris is the only quadriceps muscle that traverses both the hip and the knee joint. The rectus femoris is a powerful hip flexor, but it is largely dependent on the position of the knee and hip to assert its influence. It is most powerful when the knee is flexed, whereas significant power is lost when the knee is extended. The rectus femoris is innervated by the femoral nerve (i.e., the posterior division of L2 to L4).

I’m 6 foot and 154 pounds and I’m thinking of using this diet to bulk up before I do a cut to shed body fat for a more lean look. How good would this diet be to maintain body fat while building muscle and how much muscle could you expect to put on. Thanks. I do not want to gain that much body fat while bulking and if possible I would just like to maintain my current body fat while bulking.
A: Eat more frequently, drink less liquids while eating (they compete for stomach volume along with food), eat from larger plates and bowls, add lime or lemon juice to your water with meals (can help to increase production of hydrochloric acid that breaks down food), and consume more liquid calories (especially around the workout if appetite is suffering the rest of the day).
“Exercises such as single leg squats, regular squats, deadlifts, monster walks, side laying leg lifts, step-ups and reverse planks are some of the exercises that can strengthen the muscles," says Schulz. "You can also try a challenging lunge circuit, split squats, and deadlifts for some major toning." (And of course, if you need any further ideas, check out our roundup of the 17 best glute exercises out there.)

The majority of your workouts should be comprised of compound exercises. Common examples include squats, deadlifts, lunges, bench presses, rows, pull-ups, lat pull-downs, overhead presses, and so on. Isolation exercises should definitely also be a part of your program, just a smaller part in comparison. Common examples include bicep curls, tricep extensions, chest flies, lateral raises, leg curls, leg extensions, calf raises, and so on.
One of the biggest glutes-toning mistakes people make is relying on weight machines to tone their butts, says Metzl. Instead, try functional bodyweight training exercises like those squats and bridges we mentioned before. These moves are more effective at strengthening the layers of muscle in your glutes, he says—weight machines, on the other hand, isolate a single layer. 

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.
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.

It has been argued that purposely overtraining for a brief period can be beneficial. One article published by Muscle & Fitness magazine stated that you can "Overtrain for Big Gains". It suggested that if one is planning a restful holiday and does not wish to inhibit their bodybuilding lifestyle too much, they should overtrain before taking the holiday, so the body can recuperate and grow during the prolonged rest period. Overtraining can be used advantageously, as when a bodybuilder is purposely overtrained for a brief period of time to super compensate during a regeneration phase. These are known as "shock micro-cycles" and were a key training technique used by Soviet athletes.[53]
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. 
Firstly, let’s establish where your glutes are and what they actually refer to! Your ‘glutes’ — or your gluteal muscles, as they are more formally known — refer to the muscles in your butt. Specifically, there are three major muscles in this area: your gluteus maximus (the main, large muscle that shapes your backside), your gluteus medius and your gluteus minimus (two smaller muscles that assist the gluteus maximus in moving your body).
