Explain how calisthenics can include both isometric and isotonic exercises.
Calisthenics can be isometric when you hold a position without moving, such as holding a plank or wall sit. They can be isotonic when you move through repetitions, such as doing push-ups or squats, because the muscles shorten and lengthen as they produce force.
Which of the following statements about weight training is TRUE?
Why is it a myth that aerobic exercise is the only way to burn fat?
Aerobic exercise is not the only way to burn fat because strength training and other activities also use calories. Building or maintaining muscle through resistance exercise can support energy expenditure, and fat loss ultimately depends on overall energy balance rather than one specific type of exercise.
Explain why isokinetic exercises cannot generally be performed by individuals at home.
Isokinetic exercise uses specialized equipment to keep the movement speed constant while adjusting resistance to match the effort applied. Because most people do not have these machines at home, isokinetic exercises generally require a gym, clinic, or other facility with the proper equipment.
Explain why not everyone can become a bodybuilder, even if they train hard enough.
Hard training can improve strength and build muscle, but people differ in genetics, body structure, muscle shape and attachment points, hormone levels, and how their bodies respond to training. These factors affect how much muscle someone can develop and how it looks, so training hard cannot make everyone a bodybuilder.
A well-designed weight-training program for men targets which of the following major body areas?
Explain why it is important for a well-designed weight-training program to develop all six areas of the body.
A well-designed program develops all six major body areas—the arms, legs, chest, back, shoulders, and abdomen—so strength is balanced throughout the body. Balanced development supports posture and everyday movement and helps prevent muscle imbalances that can contribute to injury.
