progressive overload principle – to continue to gain benefits, strength training activities need to be done to the point where it’s hard for you to do another repetition. The aim is to use an appropriate weight or resistant force that will challenge you, while maintaining good technique. Also, regular adjustments to the training variables, such as frequency, duration, exercises for each muscle group, number of exercises for each muscle group, sets and repetitions, help to make sure you progress and improve
According to, women should not weight train much differently than men. Instead of using light weights and performing 15 to 20 repetitions, you should lift relatively heavy weights, and keep your repetitions to between six and 12. Your focus should be on using mostly free weights, and performing compound exercises. Compound exercises utilize both your prime mover muscle and stabilizer muscles to execute the lift. Examples of compound exercises are squats, dead lifts, lunges, incline bench press, upright rows and overhead presses. It is also important to get enough rest while you are training, as muscle growth and repair occurs during rest.
Major variants: incline ~ (more emphasis on the upper pectorals), decline ~ (more emphasis on the lower pectorals), narrow grip ~ (more emphasis on the triceps), push-up (face down using the body weight), neck press (with the bar over the neck, to isolate the pectorals), vertical dips (using parallel dip bars) or horizontal dips (using two benches with arms on the near bench and feet on the far bench, and dropping the buttocks to the floor and pushing back up.)

A good pair of legs is as important to the body as a good set of wheels is to a car. But like a quality set of wheels, strong, healthy legs come at a high price. So, don’t take the following powerful exercises—especially the sissy squat—lightly. Because this is an incredibly intense workout that will turn your thighs into killer wheels. Serious focus and intensity are required.

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]
