Major variants: reverse ~ (curling the pelvis towards the shoulders), twisting ~ or side ~ (lifting one shoulder at a time; emphasis is on the obliques), cable ~ (pulling down on a cable machine while kneeling), sit-up ~ (have [chest] touch your knees), vertical crunch (propping up to dangle legs and pulling knees to the [ chest] or keeping legs straight and pulling up legs to a 90 degree position). Reverse hanging crunch (using gravity boots or slings to hang head down and pulling to a 90 or 180 degree form)

The lower volume, high intensity workouts would not use the pyramid system because they were employing less sets for each exercise. The bodybuilders using the low volume workout would do 2-3 light sets at low intensity to warm up the muscles, joints and tendons. When they were fully warmed up, they would use the heaviest weights possible for the required number of sets. They would take the set to failure, often using advanced training techniques such as the rest-pause method, drop sets or forced reps to go beyond normal muscle failure. Because each working set was so intense, the rest periods for this workout would be longer in order to fully recuperate before taking on the next heavy set.
The Russian twist is a type of exercise that is used to work the abdomen muscles by performing a twisting motion on the abdomen. This exercise is performed sitting on the floor with knees bent like in a "sit-up" position with the back typically kept off the floor at an angle of 45°. In this position, the extended arms are swung from one side to another in a twisting motion with or without weight.

Caffeine helps to increase alertness and improves concentration. This helps you to focus on your cut. Products such as Promax Lean and Thermobol contain caffeine should you prefer not to overdo it on the coffees or want to combine this intake with protein. However, it is recommended not to exceed a daily intake of 400mg of caffeine from all sources.
When trying to gain mass, eat two breakfasts. To restock liver glycogen and put the brakes on the catabolism that chips away at your muscle overnight, down two scoops of whey protein along with a fast-digesting carb such as Vitargo or white bread immediately upon waking. One of our favorite morning shakes is two cups of coffee, two scoops of whey, and two to three tablespoons of sugar. About 60 minutes later, follow up with a wholefoods breakfast that boasts quality protein—such as Canadian bacon or eggs—and slowerburning carbs, such as oatmeal.
To get the most gain from resistance training, progressively increase the intensity of your training according to your experience and training goals. This may mean increasing the weight, changing the duration of the contraction (the time during which you sustain holding the weight at your muscle’s maximum potential), reducing rest time or increasing the volume of training.

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]
