In a study published in the journal Amino Acids, Finnish scientists discovered that weightlifters who consumed whey protein before and immediately after workouts produced more of a compound called cyclin-dependent kinase 2, or CDK2, than those who didn’t take whey. CDK2 is believed to activate muscle stem cells involved in hypertrophy and recovery from intense training. In addition, a 2009 study by Japanese researchers found that consuming whey and glucose prompted larger stores of post-training muscle glycogen (the main energy source for working muscles) than ingesting just glucose. Shoot for 20–30g of fast-digesting whey protein isolate or hydrolysate 30 minutes pre-workout and immediately post-workout.
Eat plenty of carbs. Although a high-protein diet is a must for bodybuilding, you should not eschew carbs altogether, as your body needs carbohydrates to build and process energy. Instead, make sure you are eating carbs wisely; a doughnut and a bowl of quinoa are not equals. When implementing carbs, aim for whole-grain, high-quality carbohydrates, including grains such as quinoa, brown rice, oats, and barley.[12]

Train to muscular fatigue. Many people approach an exercise with a preconceived notion of the exact number of repetitions they will do for each set. (Ten seems to be a popular choice.) These misguided souls are training inefficiently and will never reach their full potential. When performing an exercise, your goal is not a certain number of repetitions. Do not start your set saying, "I'm going to do X number of reps." Depending on the muscle group and your particular athletic objectives, you will probably want to stay within a certain range of repetitions. However, your goal is to fatigue the muscle by performing each exercise (with good form) until you no longer can.

2) Make your own home gym. In talking to thousands of trainees, it seems like the majority is better served by attending a health club as most people do not have the motivation to workout at home. However, if you are like me and like to workout in total solitude, this may be the best option for you. The advantages are obvious: no fees, no crowds, you can superset alot (move from one exercise to the next with no rest), and workout anytime. Disadvantages are that you have no one to spot you so you need to be very careful with what you are doing.

Site enhancement oil, often called "santol" or "synthol" (no relation to the Synthol mouthwash brand), refers to oils injected into muscles to increase the size or change the shape. Some bodybuilders, particularly at the professional level, inject their muscles with such mixtures to mimic the appearance of developed muscle where it may otherwise be disproportionate or lagging.[54] This is known as "fluffing".[55][56] Synthol is 85% oil, 7.5% lidocaine, and 7.5% alcohol.[55] It is not restricted, and many brands are available on the Internet.[57] The use of injected oil to enhance muscle appearance is common among bodybuilders,[58][59] despite the fact that synthol can cause pulmonary embolisms, nerve damage, infections, sclerosing lipogranuloma,[60] stroke,[55] and the formation of oil-filled granulomas, cysts or ulcers in the muscle.[59][61][62] Rare cases might require surgical intervention to avoid further damage to the muscle and/or to prevent loss of life.[63]
The mechanism on which this product works is that, it increases the blood flow to the muscles at the time of the workout. This increased blood flow, increases the supply of oxygen and nutrients to the muscles and hence contributes to their development. This product helps in increasing the strength of the body by making it more athletic. By helping in building leaner muscles, this product gives the body extraordinary pump. Besides its benefit of increasing the size of the muscles, this product is also known to have positive effects on the sexual activities of men by giving them bigger and harder erections.
