What type of training adds external resistance to natural body movements?

The type of training that adds external resistance to natural body movements is free weight training. This form of exercise involves using weights, such as dumbbells or barbells, which can be added to movements that the body is already capable of performing naturally. By incorporating these external weights, the body has to work harder to perform the same movements, which can lead to increased strength, muscle mass, and improved overall physical performance.

Free weight training allows for a wide range of motion and engages stabilizing muscles, as the individual is often required to balance and control the weight as they move through exercises. This is particularly beneficial for functional strength, which translates well into everyday activities.

Bodyweight training, while effective for strength and conditioning, does not incorporate external weights, relying solely on the individual's body weight as resistance. Plyometric training involves explosive movements that focus on improving power and speed, often without the addition of weights. Cardiovascular training primarily focuses on increasing endurance and cardiovascular fitness, without emphasizing resistance training. Therefore, free weight training stands out as the correct choice for adding external resistance to natural body movements.
