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.
Tight hip flexors can also make it harder for your glutes to activate—since they're opposing muscle groups, when one is really tight the other becomes lengthened. When a muscle is more lengthened than it should be, it takes away some of its ability to contract. When your glutes are in this compromised position, it can cause other muscles to do more work than they should, making your workouts less efficient and sometimes, increasing your risk of injury.

Another common reason I see glutes that aren’t working properly is due to injury. Often an injury happens that changes the mechanics and motor programming of a person’s body. This can lead to some muscle groups becoming overactive, while others become underactive (think: compensation). This can alter things for a long time without the person even knowing it. 
(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.
But muscle can’t turn into fat, just like mud can’t turn into gold. If you quit lifting, your muscles mass will decrease over time because there’s no training to stimulate your body to keep it. And your body-fat level will increase if you don’t start eating less (since you burn less). The obvious solution when you stop lifting is to also stop eating so much.
Don’t make the mistake of trying to bulk up when you should be on a diet. While you might have muscle on your mind, most people need to get leaner first. If you’re fat and you start eating for size, you’re only going to get fatter. Get rid of the excess blubber first, to the point where you can see some abs, and then worry about getting big. You should be as low as 12% body fat before you change your diet up to focus on mass gain. That will ensure that your insulin sensitivity is high. When it is, you can eat more carbs and your body won’t store them as fat.
Get ready: Attach an ankle collar to a cable pulley at the lowest setting. Wrap the strap around one ankle, then step about three feet away from the pole. Lie facedown on a stability ball so your stomach and upper thighs rest on it, then place the toes of your non-working foot on the floor behind you and your hands shoulder-width apart on the floor in front of you. 
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.

The best way to know the real progress you’re making is by recording it on video or taking photos. “Photos mean everything because if you can take them in the same areas and in the same poses, you’ll see your strengths and weaknesses clearly,” says Heath. “Revise your training and diet programs to eliminate weaknesses.” Keep a file of your progress to see just how far you can take your fitness.


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!

The iliopsoas muscle is the prime hip flexor and shortening may affect the lower back, pelvis, and/or hip joint. Caution should be taken during this release due to the sensitive area in which the therapist's hand pushes, i.e. proximity to the appendix, possible abdominal aortic abnormalities, potential tissue weaknesses predisposing to inguinal hernias, ovarian conditions, or general irritation/inflammation of the gastrointestinal system; hence, this release may occasionally be replaced by the regular therapeutic stretch presented in Chapter 7 (see Fig. 7.14).
If you touch your phone between exercise sets, it better be to set its timer to 30 to 90 seconds. When lifting for hypertrophy, rest periods of 30 to 90 seconds encourage a quick release in muscle-building hormones (including testosterone and human growth hormone) while also making sure that you really, truly fatigue your muscles, according to Fitzgerald.
Now, while all three are definitely beneficial to the process, I’d consider metabolic stress and muscular damage to be of secondary and tertiary importance, respectively. In addition, they are also things that will pretty much take care of themselves when implementing the workout guidelines and recommendations we’ve already covered (namely for volume, rep ranges, rest periods and exercise selection).
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.

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]
