Which training method is least likely to include flexibility exercises?

The training method that is least likely to include flexibility exercises is yoga. Yoga is fundamentally centered around promoting flexibility, balance, and strength, often integrating extensive stretching and postural exercises. In contrast, plyometrics, circuit training, and interval training can incorporate flexibility components, but these methods primarily focus on explosive strength, endurance, and cardiovascular fitness.

Plyometrics emphasizes high-intensity exercises that improve power and speed through dynamic movements, often involving jumping or explosive actions. While flexibility can be beneficial for performance and injury prevention in plyometrics, it is not a primary focus.

Circuit training combines different exercise stations, often targeting strength and cardiovascular fitness across various muscle groups. Flexibility exercises may be included as part of a complete workout but are not the core element of circuit training.

Interval training is structured around alternating periods of high-intensity exercise and rest or lower intensity. It primarily aims to enhance aerobic and anaerobic fitness, so while stretching might be included as a warm-up or cool-down, it is not central to the method.

In summary, yoga is distinct from these training regimens as it places the highest emphasis on flexibility, making it the clear choice for the method least likely to exclude flexibility exercises.
