Let's get one thing clear: It's all about the bum. Sure, built biceps fill out a shirt and six-pack abs are the prize of every beachgoer, but the back is where it's at. A bodacious booty is essential to a good physique—and not just for stage-bound fitness contestants. Everyone seems to want a great bum. Photos of posteriors flood the Internet and are often the most viewed—and "liked"—body part on social media. There's just something magical about a beautiful butt!
Homocysteine is produced after S-adenosyl methionine is used up (as donating a methyl group creates S-adenosylhomocysteine, which then produces homocysteine) mostly from phosphatidylcholine synthesis[307] and its reduction (via either methylation from trimethylglycine via betaine:homocysteine methyltransferase, urinary excretion, or convertion into L-cysteine via cystathionine beta-synthase[308]) is thought to be therapeutic for cardiovascular diseases.

In addition to the BBB, SLC6A8 is also expressed on neurons and oligodendrocytes,[192] but is relatively absent from astrocytes, including the astrocytic feet[193][194] which line 98% of the BBB.[195] Creatine can still be transported into astrocytes (as well as cerebellar granule cells) via SLC6A8, as incubation with an SLC6A8 inhibitor prevents accumulation in vitro. It seems to be less active in a whole brain model, relative to other brain cells.[196]
I always recommend starting on the low end of the scale. Only increase volume when you absolutely need to. So, if you’re training chest, you could do 6 work sets of dumbbell bench presses to start out, breaking down to two sets per workout for three sessions per week. You can gradually add sets from there, experimenting with different training splits that will allow you to get in more volume without overtraining (we’ll discuss training splits next).
Another study demonstrated that females receiving 4 days of high-dose creatine intake (20 g/day) followed by low-dose creatine intake (5 g/day) during 10 weeks of resistance training (3hours/week) increased muscle PCr concentrations by 6%. Also, maximal strength of the muscle groups trained increased by 20-25%, maximal intermittent exercise capacity of the arm flexors increased by 10-25% and fat-free mass increased by 60% [11].
If you're using a resistance band, keep in mind that one band might not cut it for your entire body. Different muscles have different strengths, so you may want to buy two different resistance bands in different thickness, which determines how difficult they'll be to use. In general, if you're able to complete 8 reps of an exercise using a band, you'll want to select another that provides a greater amount of resistance. 
Men appear to have higher active creatine-kinase systems, and racial differences favor black people over hispanic people over white people in terms of the activity of the creatine-kinase system. This system is more variable in men, independent of supplementation. Exercise may increase the activity of the creatine-kinase system independent of supplementation.

A great analogy that I like is that the balance between training and recovery is like digging a hole. Each time you lift, you dig yourself deeper and make it harder to climb out of the hole. To get back out again, you have to fill in the hole to return to ground level, and the only way to fill it is with food and rest. If you overdo it in the gym by pushing too hard, you won’t be able to train as often or at a high capacity. Eventually, you’ll get injured.
Testosterone is necessary for normal sperm development. It activates genes in Sertoli cells, which promote differentiation of spermatogonia. It regulates acute HPA (hypothalamic–pituitary–adrenal axis) response under dominance challenge.[22] Androgen including testosterone enhances muscle growth. Testosterone also regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans.[23][24] 

Bodybuilders have THE BEST mind to muscle connection of any resistance-training athletes. Ask a seasoned bodybuilder to flex their lats or their rhomboids or their hamstrings and they will do it with ease. Ask other strength athletes and you will see them struggle and although they may tense up the target muscle they will also tense up about 15 other surrounding muscles. This is because strength athletes train MOVEMENTS. They don’t care about targeting their lats. They just want to do the most pull ups. They don’t worry about feeling their quads. They just want to squat maximum weight. Although this is an expected and positive thing for the most part, there are real benefits to being able to isolate and target muscles.
Below (in no particular order) are the top glute exercises to incorporate into your fitness regimen. You can mix and match these in multiple combinations for awesome glute and overall lower body work. Sets and reps for each exercise depends on your particular needs, goals, and current abilities. But, 2-5 sets of 8-15 reps is Reames’ general recommendation. 
1. Train each muscle group twice per week. To maximize muscle growth, plan to train every major muscle group at least twice per week. According to a 2016 Sports Medicine review, even if you don't work that muscle any harder or longer, by simply dividing your chest, leg or back workout into two days, you'll spur more muscle growth. While the jury is still out on whether training each muscle group three days per week is better than two at spurring hypertrophy, it is likely better suited toward experienced lifters than beginners, Matheny says.
Age-related muscle loss: Many different dosing regimens have been used; however, most use a short-term “loading dose” followed by a long-term maintenance dose. Loading doses are typically 20 grams daily for 4-7 days. Maintenance doses are typically 2-10 grams daily. Older adults seem to only experience benefits from creatine supplementation when it is combined with resistance training.
While there are many reasons why an individual might have weak glute muscles, one of the main causes is that many of us are living increasingly sedentary lifestyles. Many jobs now involve people sitting down for a big part of their day, or after a long day of work we go home and sit on the couch; this means that the gluteus muscles can become dormant more than they should be. Another reason why someone might have weak glutes could be because of poor form and generally over-relying on other muscles during everyday movements, which contributes further to the muscles remaining inactive. 
In isolated striatal cells (expressing creatine kinase), seven day incubation of 5mM creatine (maximal effective dose) appears to increase the density of GABAergic neurons and DARPP-32 (biomarker for spiny neurons[225]) with only a minor overall trend for all cells[226] and showed increased GABA uptake into these cells, as well as providing protection against oxygen and glucose deprivation.[226]

In addition to ALL of the above, strength training is fun! Whether you are looking for the most effective 20-30 minute workout (to stay fit and look great naked), or are looking for a competitive sport that you can really get into, strength training can help you meet your goals. It’s easy and fun to see progress as you strength train, almost like leveling up. And if you’re looking to improve in other areas (a sport, traditional cardio, or an activity like rock climbing), strength training is an easy choice!


Creatine is an organic acid naturally occurring in the body that supplies energy to muscle cells for short bursts of energy (as required in lifting weights) via creatine phosphate replenishment of ATP. A number of scientific studies have shown that creatine can improve strength,[32] energy,[33] muscle mass, and recovery times. In addition, recent studies have also shown that creatine improves brain function.[34] and reduces mental fatigue.[35] Unlike steroids or other performance-enhancing drugs, creatine can be found naturally in many common foods such as herring, tuna, salmon, and beef.

So how do you build a stronger backside? Squats are a good place to start. But if you really want to get your booty rock solid, it’s a good idea to incorporate weights, resistance bands, stability balls and even foam rollers into your glute workout. Here are 50 butt exercises that will help you think outside of the box when it comes to squats, lunges, glute bridges, leg lifts and more.


Creatine is known to occur in highly concetrated levels in chicken photoreceptors, relative to other parts of the eye (10-15mM[466]) alongside high levels of creatine kinase.[466] The creatine transporter in human eyes also seems to be concentrated in the photoreceptors,[468] which are known to be susceptible to hypoxic cellular death[471][472] which, for humans, usually means retinal detachment.[473]
