The triceps brachii is the muscle group located at the back of the upper arm. It is responsible for extending the elbow joint, allowing for movements such as pushing and straightening the arm.

Hypertrophy refers to the increase in the size of muscle cells, leading to an overall increase in muscle mass. This process is stimulated by resistance training and proper nutrition.

Carbohydrates, proteins, and fats are the three macronutrients that provide the body with energy and building blocks for muscle growth. Vitamins are essential micronutrients, but they are not macronutrients.

Bodybuilders typically require a higher protein intake compared to sedentary individuals. The recommended daily protein intake for bodybuilders is generally between 1.2 and 1.7 grams per kilogram of body weight.

The barbell bench press is a compound exercise that primarily targets the chest muscles, particularly the pectoralis major and minor. It involves lying on a bench and pressing a barbell upwards from the chest.

The pump is a temporary increase in muscle size and fullness that occurs during and after a workout. It is caused by an increase in blood flow and fluid accumulation in the muscle tissue.

Creatine is a natural substance that helps supply energy to muscle cells during high-intensity exercise. It is commonly used by bodybuilders to improve muscle strength, power, and growth.

Cutting is a phase in bodybuilding where the focus is on reducing body fat while preserving or even increasing muscle mass. This is achieved through a combination of diet and exercise adjustments.

Push-pull-legs, upper-lower, and bro split are common training splits used by bodybuilders to target different muscle groups on different days. Full-body workouts, on the other hand, involve training all muscle groups in a single workout session.

Failure is the point during a set of an exercise where a muscle is unable to perform any more repetitions with the same weight. This is often used as a training technique to stimulate muscle growth.

The barbell row is a compound exercise that primarily targets the back muscles, particularly the latissimus dorsi and rhomboids. It involves pulling a barbell towards the chest while keeping the back straight.

Progressive overload is a training principle that involves gradually increasing the weight or resistance used in an exercise over time. This is done to challenge the muscles and stimulate muscle growth.

Men's physique, women's bodybuilding, and classic physique are all common types of bodybuilding competitions. Powerlifting, on the other hand, is a strength sport that focuses on lifting heavy weights in three main lifts: squat, bench press, and deadlift.

The stretch reflex is an involuntary contraction of a muscle after it has been stretched. This reflex helps to protect the muscle from injury and maintain muscle tone.

The squat is a compound exercise that primarily targets the quadriceps muscles, particularly the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. It involves lowering and raising the body by bending and straightening the knees.
