Why less volume for the smaller muscle groups, you ask? Partially because they are smaller, but mostly because they get a ton of indirect volume while training the bigger muscle groups (e.g. your biceps get hit pretty hard while training back, triceps get hit pretty hard while training chest and shoulders, shoulders get hit pretty hard while training chest, etc.).
While leg lifts, certain ab exercises, and even hula hooping can all help work the hips, the hip flexors can still be a tricky part of the body to stretch Kinetics of hula hooping: An inverse dynamics analysis. Cluff, T., Robertson, D.G., and Balasubramaniam, R. School of Human Kinetics, University of Ottawa, Ottawa, Ontario, Canada. Human Movement Science, 2008 Aug; 27 (4): 622-35.. To get them even stronger and more flexible, try these five simple hip flexor stretches:
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. 
You don't need to design a fresh plan every three weeks. Scaling up weight and modifying reps are obviously both important for progression, but playing with different set styles will shock your body and keep things interesting. Remember, bodybuilding isn't meant to feel like a chore. Below, we explain eight different types of sets to help you build muscle more efficiently during bodybuilding training.
The hip flexor muscles flex the hip during swing. They are particularly important for initiating swing91 when walking at slow speeds. Without adequate hip flexion during swing, knee flexion is more dependent on hamstring muscle activity.59 Patients with paralysis of the hip flexor muscles attempt to advance the swing leg by either externally rotating the hip and using hip adductor muscles as hip flexors or by circumducting the leg.59,61 The effects of hip flexor muscle paralysis on gait are particularly evident when walking up stairs or slopes, which requires lifting the leg.
Dynamic stretching (stretching while in motion), is the most efficient way to lengthen and strengthen the hip flexor muscles. An exercise that you can do that will engage the core and all of the lower extremity muscles while focusing on the hip flexors is called the Single Leg Split Squat. Remember that the rectus femoris crosses the hip and knee joint. This exercise involves both the hip and knee joint, making it an appropriate exercise to train the rectus femoris as well as the iliacus.
Foundational supplements are often overlooked for building muscle, because they work behind the scenes. In actuality, foundational supplements are important to take for building muscle, because they assist with overall health and wellness and contribute to the effectiveness of other muscle building supplements.* Some of the top foundational supplements are:
This exercise is challenging and will certainly be beneficial even without weights. If you can execute perfect form with your body weight, you can make the exercise harder by adding weights to your hands, by stepping on an unstable surface with your front foot (balance disc, foam pad), or you can place your rear leg on an unstable surface such as a physioball. You should be able to comfortably perform 2-3 sets of 10 reps on each leg before advancing this exercise.
How to do it: Lie on your back with your feet planted firmly on the floor, knees bent. If you’re just starting and using your bodyweight, reach your arms straight up over your chest and clasp your hands. If you’re using dumbbells, place the weight (plate, kettlebell, dumbbells) comfortably on your pelvis and hold it steady. To really activate your glutes, thrust your hips up toward the ceiling, driving with your legs, and dig your heels into the floor. Lower your hips until they’re hovering right above the floor level, then repeat.  
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.
“Don't get set into one form, adapt it and build your own, and let it grow. Be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot. Now water can flow or it can crash. Be water, my friend.” Bruce Lee
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.
A: If your goal is the largest accrual of muscle mass possible then there may be some benefit to ingesting nutrients with a period of 30-60 minutes after your workout. Does this have to be a protein shake? No, but ideally it should be a meal lower in fat to enhance the digest rate of nutrients within the gastrointestinal tract. However, if you have just eaten a mixed macronutrient meal pre-workout then you should keep in mind that that meal is still likely digesting so there’s no need to throw down the weights after your last set and rush to your locker to slam a protein shake.
A 2001 study at the University of Texas found that lifters who drank a shake containing amino acids and carbohydrates before working out increased their protein synthesis more than lifters who drank the same shake after exercising. The shake contained 6 grams of essential amino acids — the muscle-building blocks of protein — and 35 grams of carbohydrates.
Athletes with relative shortening of the hip flexors and accompanying weakness of hip extensors will exhibit decreased hip extension at terminal stance phase or “toe off.” Athletes who lack hip extension may also exhibit related limitation in great toe extension. Often these athletes will show decreased wear under the great toe aspect of their shoe sole and relative increased wear under the more lateral toes. These athletes may also demonstrate increased hip flexion at initial contact or “heel strike” in an effort to make up for the shorter stride length caused by limited hip extension. In patients with knee instability this will contribute to hyperextension or “giving way” of the knee.13
Just because your hip flexor region feels sore doesn’t necessarily mean the muscles there are tight — in fact, they might need strengthening. This is where that sports science debate we mentioned earlier comes into play. It’s important to identify whether you’re tight or if the muscles are weak. Again, the Thomas Test will help you identify if you’re maybe stretching something that actually needs strengthening. 

For many people, appearance is the top priority when it comes to their posterior. But yoga practitioners also know that the glute muscles can do so much more than look great in jeans: They’re the primary players in many of the movements that make it possible to do yoga. The gluteus maximus, medius, and minimus—along with many other smaller, supporting muscles—act as a base of support for the pelvis and hips. What’s more, these hard-working muscles stabilize your femur (thighbone) in your hip socket, rotate your femur internally and externally, and draw your leg back. And yes, all of these actions also help us stand and walk, and even support us when we sit.
There are many camps within the weight training fitness community. We have bodybuilders, Crossfit athletes, powerlifters, Olympic lifters, and strongman athletes just to name the most popular ones off the top of my head. One thing they all have in common is that they all use resistance to achieve a particular goal. They all also “share” particular exercises. Most resistance-training athletes do barbell squats, overhead presses and deadlifts. I can write pages of differences between each of the disciplines I listed above and I can also write quite a bit about their similarities but one form of resistance training is MORE different than the others. Bodybuilding is the only sport that judges the appearance of the athlete rather than their performance. This may be why bodybuilders tend to get poked at the most.
If the iliopsoas and other hip flexors are tight, they pull down and forward on the pelvis, which tilts the pelvis forward and compresses the lower back. Picture a man standing with the front of his pelvis tilting forward and his tailbone lifting. To stand upright, he has to overarch his lower back. Anatomically, this is called hyperextension; commonly, it's called "swayback." Prolonged standing or sitting in this position increases pressure on the facet joints of the lower spine, which can contribute to arthritis in those joints.
If your fitness goals are to get strong and build hard, visible muscle, then you’re going to want to train in three phases according to Heath. Strength, conditioning, and a blend of the two that works for you. “If you can get to the gym 4-5 days a week, that would be perfect,” he says. “You can still do chest/tri’s, back/bi’s, legs, shoulders, and make the fifth day a cleanup day, meaning focus on body parts you may be weaker in.” Check out Heath’s guide to finding your best muscle-building routine.
(1) Water - I drink this all the time. Mainly in the morning. Doesn’t it make sense to hydrate upon waking up? I use to get nauseous, but that was because of a poor “diet”/food choices. Now, it’s like a filtering fluid at this time of day (morning). I drink it all day, but I have like 1 water bottle every hour. It’s easy to remember and to do (well, for me). We should aim for around 100oz of water, consuming all this in one time would suck. So “timing” water (which is a nutrient) is considered “nutrient timing”.
A: First, you have to realize that when one is gaining weight it’s nearly impossible (steroid discussion aside) to gain solely muscle without the acquisition of some body fat as well. That being said though, you can improve thedistribution of lean body mass to fat mass by ensuring that your calorie consumption isn’t too aggressive (i.e. 1000+ over your BMR). Also, it should go without saying, but you need to be training hard while focusing on progressive overload to ensure that the calories you’re ingesting are actually going towards muscle growth. You shouldn’t be neglecting cardiovascular work either; both HIIT and LISS each play a role in enhancing mitochondrial density, balancing neurotransmitters, improving oxidative capacity, and influencing brain plasticity.
(5) Fasting helps - sure, it helps, but one needs to understand why. Fasting is for when we sleep. When we sleep we are not eating. That is fasting. Fasting during the day is a religious practice and I’m not sure how “fasting” in nutrition got started, but it’s wack. I feel someone didn’t eat for awhile and noticed a change that they liked. Well, duh. Not eating is what helped you. Fasting takes away time to eat. Less time to eat means less food consumed. Less food consumed is less calories. Less calories should help enter into a deficit. It’s the deficit that is helping, fasting is just a way to get there. For instance: If I sleep at 9pm every night, but one night I had to do something until 11pm. Let’s say this night I didn’t have any food or water around me. That’s okay, but I usually sleep at 9pm which means my body is going to be awake for 2 more hours than usually. During these 2 hours I will be using energy that I’m not usually using because I would be sleeping. This energy used during these 2 hours is a “fast”. Why? Because I’m doing the same thing as if I was sleeping, but I’m awake. Being awake is going to use more energy. Or think about it this way: I wake up at 7am everyday, but one day I wake up at 9am. Those two hours I slept in was lost time for me to eat which means I was fasting. For someone that wants to eat less, they need to make less to eat or just eat less. Sleeping in creates less time. Now, I could regain those calories back by eating more during the day or staying up later and eating it back. Make sense?

Most typical bodybuilding programs have way too many sets and reps and use the wrong exercises. However, if you lower the total volume, go heavier, and use compound movements as I’ve outlined above, there is nothing wrong with a body-part split for advanced lifters. In fact, it’s often less stressful to the joints than your average upper/lower split.
