Creatine supplementation may be able to enhance lifespan, secondary to increasing intracellular carnosine stores. Carnosine is the metabolic compound formed from beta-alanine supplementation, and in a mouse-model for premature aging (senescence-accelerated premature aging, SAMP8) creatine supplementation without any beta-alanine has been shown to increase cellular carnosine stores. That being said, the aforemented SAMP8 study noted an increase in carnosine levels at middle age, but not old age in the mice. A human study using 20g of creatine for one week in otherwise healthy people failed to find an increase in intracellular carnosine stores.

It’s true—your genes can play a role when it comes to building muscle. In general, there are two types of muscle fibers: Type I, which are slow twitch, and Type II, which are fast twitch. Depending on which you have more of, you may have an easier or harder time gaining muscle. “Fast twitch muscle fibers are two times as thick as slow twitch muscle fibers, lending to the overall thickness of the muscle without any activity,” explains Lovitt. “Those people with a genetic predisposition of a high percentage of these fibers can increase muscle size very easily while the people with a higher percentage of slow twitch muscle fibers have to work really hard to put on mass.” It’s the reason why a world-class sprinter genetically has more fast twitch muscle fibers than a world-class marathoner—it comes down to what we’re born with.
While most of these muscle building supplements can be taken at any time of the day, some are best to include in your pre-workout routine. Citrulline malate, in particular, is one that should be taken about an hour ahead of your workout. Because this supplement boosts performance, taking it ahead of your workout will maximize its effect, making sure you get the most out of the supplement.
An isolation exercise is one where the movement is restricted to one joint only. For example, the leg extension is an isolation exercise for the quadriceps. Specialized types of equipment are used to ensure that other muscle groups are only minimally involved—they just help the individual maintain a stable posture—and movement occurs only around the knee joint. Most isolation exercises involve machines rather than dumbbells and barbells (free weights), though free weights can be used when combined with special positions and joint bracing.
If you want to take creatine as a supplement for bigger and stronger muscles, then the standard protocol is to have a “loading period” where you significantly increase your creatine intake for a few days or weeks. “This can prime your muscles to increase the amount of creatine that they ‘hold,’” explains Bates. “During the loading period, you generally take 5 g of creatine four times per day. After the loading period, you decrease the amount of creatine you take to a ‘maintenance’ level of 3 to 5 g per day.” (That’s also the recommendation from the International Society of Sports Nutrition.)

For beginners, your own body weight might be enough to get you started. However, it can be hard to challenge your body without any additional resistance, so to progress, you'll need some equipment. If you decide to strength train at home, you'll want to invest in some basics, such as resistance bands, weights, and an exercise ball. Try to have a range of weights: a light set (3 to 5 pounds for women, 5 to 8 pounds for men), a medium set (5 to 10 pounds for women, 10 to 15 pounds for men), and a heavy set (10 to 20 pounds for women, 15 to 30 pounds for men).
The majority of studies focusing on creatine supplementation report an increase in the body’s’ creatine pool [15-17]. There is a positive relationship between muscle creatine uptake and exercise performance . Volek et al  observed a significant increase in strength performance after 12 weeks creatine supplementation with a concurrent periodized heavy resistance training protocol. The creatine supplementation protocol consisted of a weeklong loading period of 25 g/d followed by a 5 g maintenance dose for the remainder of the training. These positive effects were attributed to an increased total creatine pool resulting in more rapid adenosine triphosphate (ATP) regeneration between resistance training sets allowing athletes to maintain a higher training intensity and improve the quality of the workouts along the entire training period.
The first U.S. Women's National Physique Championship, promoted by Henry McGhee and held in Canton, Ohio in 1978, is generally regarded as the first true female bodybuilding contest—that is, the first contest where the entrants were judged solely on muscularity. In 1980, the first Ms. Olympia (initially known as the "Miss" Olympia), the most prestigious contest for professionals, was held. The first winner was Rachel McLish, who had also won the NPC's USA Championship earlier in the year. The contest was a major turning point for female bodybuilding. McLish inspired many future competitors to start training and competing. In 1985, a movie called Pumping Iron II: The Women was released. It documented the preparation of several women for the 1983 Caesars Palace World Cup Championship. Competitors prominently featured in the film were Kris Alexander, Lori Bowen, Lydia Cheng, Carla Dunlap, Bev Francis, and McLish. At the time, Francis was actually a powerlifter, though she soon made a successful transition to bodybuilding, becoming one of the leading competitors of the late 1980s and early 1990s.
No. It’s not easy for everyone to get the recommended amount of protein in their diets through good eating habits alone. Others may not have clinically low testosterone, but still benefit from boosting their levels to improve their muscle building capacity. You can fix these common problems through muscle building supplements. These easy to take pills and powders can also help you boost your performance at the gym which will, in turn, spur your body’s muscle building and recovery response.
