Correct Answer: deep breathing
the question asks to identify which option among the provided choices is not a method of resistance training. the options are: free weights (barbells and dumbbells), machines, one's own body weight, and deep breathing.
resistance training, also known as strength training, involves exercises that improve strength and endurance by exercising a muscle or a muscle group against external resistance. the primary goal of resistance training is to progressively overload the muscles to stimulate muscle growth, increase strength, and enhance muscle endurance.
free weights, such as barbells and dumbbells, are classic tools for resistance training. they are versatile and allow a wide range of motion. using free weights involves more stabilizing muscles, which can lead to better overall muscle growth and strength as they require the exerciser to maintain balance and control the weights throughout the exercise movement.
machines are another common form of resistance training. they are often used in gyms and provide a controlled motion path for the exercise, which can reduce the risk of injury and is helpful for beginners. machines typically target specific muscle groups and are easier to use, as they often require less technique than free weights.
using one's own body weight as resistance is also a form of resistance training. exercises like push-ups, pull-ups, and squats use the weight of the body to provide resistance against gravity. this method is convenient because it doesn't require any special equipment and can be performed almost anywhere.
deep breathing, on the other hand, is not a form of resistance training. while deep breathing is beneficial for overall health, stress reduction, and can enhance the performance of exercise by improving oxygenation and stability, it does not provide the external resistance necessary to qualify as resistance training. deep breathing is more commonly associated with practices like yoga, meditation, or as a technique to enhance other forms of exercise by ensuring that the muscles receive adequate oxygen during workouts.
therefore, among the options provided, "deep breathing" is the correct answer as it does not involve resistance training. it does not directly contribute to muscle strengthening in the way that lifting weights, using resistance machines, or performing body-weight exercises do.
