Running with a sway to one side or experiencing muscle spasms? If your gait is off, it could be a sign of weak glutes. “A stiff hip joint would usually cause a more severe or obvious altered gait. If there is hip stiffness/poor mobility in the hip joint, it will lead to abnormal movement in all of the hip stabilizer muscles, including the glutes, and eventually pain and weakness,” Bayes explains.
Take your vitamins. In addition to a well-balanced diet, include a multivitamin supplement to your dietary regimen. It will ensure that your body is getting the full amount of vitamins and minerals it needs to stay healthy. There are many options, depending on your age, your sex, and your particular health and diet needs. Find the one that's right for you, and make it part of your daily routine.
The hip flexors are a group of muscles in the front of the hip that act to lift the knee and bring the thigh towards the abdomen. The major muscles making up the hip flexors that we will focus on are the iliacus and the psoas, or the iliopsoas and the rectus femoris. The rectus femoris  is a “two joint muscle” because it crosses both the hip and knee joints. As a group, the hip flexors have attachments on the lumbar spine, the pelvis, and the femur. In addition to their major function of flexing the hip, their attachment on the spine makes them an important part of the core muscles and spinal stabilizers.

Build an effective exercise routine. A good diet is required for your body to be able to maximize your potential, but there's no potential at all until you start the process of tearing down your old muscles and rebuilding them bigger, bulkier, and stronger. The best way to do that is to start at the beginning. If you're not sure where to begin, find a solid workout program online and try it out for a while. Don't immediately jump from one program to the next - you'll end up keeping yourself from making steady progress.
It’s a lofty goal: Gain 10 pounds of muscle in just one month. While such results are aggressive and can’t continue at the same torrid rate indefinitely, we’ve seen firsthand individuals who’ve followed our mass-gaining programs and reached double digits in four short weeks, averaging gains of 2-3 pounds a week. Trust us, it can be done. But if there’s one thing such a bold goal needs, it’s an ambitious training and nutrition strategy. In regard to nutrition, don’t even think about taking that aspect lightly. You can work out all you want, but if you don’t ingest adequate calories and macronutrients, you won’t build muscle. What and when you eat is paramount to your results, and you’ll find all you need to know about gaining mass in a short amount of time in our bulking diet meal plan.
Functional strength: Exercises designed to strengthen multiple muscle groups simultaneously. Instead of a single muscle exercise, such as as bicep curl, functional strength exercises, such as a push up, strengthen all of the muscles in the shoulder simultaneously. When you move normally, muscles work together, so it just makes more logical sense to exercise them together as well. 
(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”.
Rest your hip. Sore hip flexor muscles can benefit from rest. Avoid the activities that caused your pain. Ice your affected hip for 20 minutes at a time, several times a day. Keep the leg of your affected hip elevated as much as possible 48 hours from the first onset of pain. You can also take over-the-counter pain medications to help control pain. 

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.
I fortunately remember the nutrition label for many foods. If it doesn’t have a label, I remember what I’ve studied. It just sticks mentally and saves me time as I don’t have to input my calories via tracking. I use to track calories (started like 5yrs ago) which did help me get a better understanding (started to remember within 6m) of which foods had what and at what amount.
(4) Fats mixed with Carbs make you even more fat. I other words: Fats with Carbs can lead to retaining more fat. Remember fats get stored as fat and carbs will only get stored as fat once glycogen is full. Which means….if your glycogen is full and you combine carbs and fats in a meal…then yes, you will store more fat compared to eating just fats or carbs by itself. Why? Well, fats get stored as fat and then the carbs have to get stored as fat as well due to glycogen being full….that is stored fat from two sources, rather than just one. If your glycogen wasn’t full, then only the fats would get stored and the carbs would just go towards glycogen. This is my next point for you.
Athletes with marked weakness of the hip abductors will exhibit the classic Trendelenburg gait pattern. Hallmarks of the Trendelenburg gait pattern are depression of the swing phase pelvis (as the stance phase hip abductors cannot resist the pull of gravity on the unsupported side of the body).4,8,13 Athletes often find ways to compensate for a relative weakness, such as with a compensated Trendelenburg gait pattern. With this pattern the athlete exhibits increased deviation of the body in the frontal plane toward the stance leg. This causes a decrease in the moment arm of gravitational forces pulling on the unsupported half of the body and a relative decreased load on the stance phase hip abductors (Table 12-1).8,13

If you’re a beginner, you should train with three full-body workouts per week. In each one, do a compound pushing movement (like a bench press), a compound pulling movement (like a chinup), and a compound lower-body exercise (squat, trap-bar deadlift, for example). If you want to add in 1–2 other exercises like loaded carries or kettlebell swings as a finisher, that’s fine, but three exercises is enough to work the whole body.

And how much should you work out? According to the American College of Sports Medicine guidelines, beginners should do at least two days per week of any type of strength-training exercise. Your workout should consist of 8 to 12 repetitions each of 8 to 10 different exercises working all the major muscle groups -- chest, back, shoulders, arms, abdominals, and legs. (A repetition is how many times you lift the weight, pull the rubber tubing, do a pushup, or whatever.)

You may hear a clicking noise when you move your hip, but that sound is not necessarily a hip flexor issue. Siegrist says the clicking isn't generally the hip flexor alone and often comes from a moving part, like the joint. "Maybe there is a loose body in the joint or loose cartilage at the edge of the hip joint that is mechanically getting irritated,” she says.

There are many potential reasons, but I am going to keep it simple and give you just two. The first and most common reason people suffer from underactive glutes or “glute amnesia” is due to lifestyle. Even when people train hard every day, if they spend the majority of the remainder of the day sitting down, then they are simply not using their glutes. And remember the old saying - if you don’t use it, you lose it. Unfortunately, this is just what happens with your glutes.
How to do it: Begin with one foot firmly planted in front of you with your other leg extended back. Keep balance by putting your weight in the ball of your front foot and the back heel of your back foot. Hold a dumbbell in either hand, arms at your sides. Or, place a resistance band under the foot of your working leg, up, and around the same shoulder. Stand tall and bend your front working leg to approximately 90 degrees, keeping your knee directly over your ankle so it doesn’t over-extend. Return to the start position and repeat. Do both sides.
