What type of training involves performing the same exercise at a steady pace for at least 30 minutes?

Continuous training is the correct answer because it refers to a training method where an individual performs a specific exercise at a steady and consistent pace for an extended period, typically for 30 minutes or more. This type of training is particularly beneficial for improving cardiovascular endurance, as it keeps the heart rate elevated over the duration of the activity, allowing for sustained aerobic exercise.

Interval training, on the other hand, involves alternating between periods of high-intensity exercise and lower-intensity recovery, which is different from the steady-state approach of continuous training. Circuit training typically consists of a series of strength training exercises performed in sequence with little rest in between, focusing more on muscular endurance and strength than prolonged cardiovascular endurance. Resistance training primarily involves exercises that focus on building strength and muscle mass through weights or resistance bands and does not emphasize prolonged activity in a steady state like continuous training does.
