Splits. A term used to describe how you organize your workout. For instance, you might decide to work only your chest on day one and your back on day two. This is the type of lifting you do once you get stronger and more experienced. This is not necessary or recommended for beginners because it's too intense. It's not only unnecessary but it could lead to injury or overtraining (burnout).

There are so many great strength- and muscle-building exercises to choose from, so picking the 10 best bodybuilding exercises is a tough (and subjective) task. But the following exercises have withstood the test of time, outlasted every fitness fad and trend, and continue to be the most reliable exercises for bodybuilders. Go ahead, ask any hardcore fitness fanatic and chances are, all of these moves are in their regular arsenal.

To know how far 12 weeks of hardcore training have taken you, you’ll need to know where you began. In “Week 0” - a single workout to be performed one full week before taking on the rest of the program - devote an entire gym session to finding your three-rep max on five multijoint lifts. Your performance will provide you with a fair assessment of your strength so you can accurately measure your gains at the end of the program (Week 13).
What we love about descending sets is that this technique is really useful for hitting all the muscle fiber types in the muscle group being worked. We personally love using it for calves and biceps and it works really well on machine exercises where all you have to do is change the pin, such as: Leg Extensions, Leg Curls, Triceps Pushdowns, Lat Pulldowns, Low Pulley Rows, Calf Raise, etc. You can use this technique more often than the ones we have presented already.

The bent-over row is performed while leaning over, holding a weight hanging down in one hand or both hands, by pulling it up towards the abdomen. This is a compound exercise that also involves the biceps, forearms, traps, and the rear deltoids. The torso is unsupported in some variants of this exercise, in which case lifting belts are often used to help support the lower back.
In his phenomenal book "The Power of Habit: Why We Do What We Do In Life and Business," Charles Duhigg dedicates an entire chapter to what he labels the "habit loop." Without giving away any spoilers—I'm not kidding, it's a book that will melt your brain, and you should read it—Duhigg explains that one of the most fail-proof ways to create a habit is to preface the behavior you want to reinforce with a cue.
For some guys, the answer to the exercise question will always be that they're looking to put on muscle. Whether you have a very specific goal, like getting into figure contests and bodybuilding, or you just want to fill out a t-shirt, you have to start somewhere, even if you've always struggled to add and keep weight onto a skinny frame in the past.
Carbohydrates play an important role for bodybuilders. They give the body energy to deal with the rigors of training and recovery. Carbohydrates also promote secretion of insulin, a hormone enabling cells to get the glucose they need. Insulin also carries amino acids into cells and promotes protein synthesis.[26] Insulin has steroid-like effects in terms of muscle gains.[27] It is impossible to promote protein synthesis without the existence of insulin, which means that without ingesting carbohydrates or protein—which also induces the release of insulin—it is impossible to add muscle mass.[28] Bodybuilders seek out low-glycemic polysaccharides and other slowly digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat. However, bodybuilders frequently do ingest some quickly digesting sugars (often in form of pure dextrose or maltodextrin) just before, during, and/or just after a workout. This may help to replenish glycogen stored within the muscle, and to stimulate muscle protein synthesis.[29]
