According to Canada's physical activity guide, which of the following activity groups is not recommended?

The recommendation for power activities being performed 1 - 3 days per week aligns well with the guidance provided by Canada’s physical activity guidelines. These guidelines suggest incorporating different types of physical activities throughout the week, including endurance, strength, flexibility, and power activities. Power activities, focusing on explosive movements and quick bursts of energy, can be demanding and typically do not require as frequent a practice as some other forms of exercise for most individuals.

In contrast, the other activity categories—endurance, flexibility, and strength—are recommended within specific frequency ranges to promote comprehensive fitness and health benefits. For instance, endurance activities are often encouraged to be done more frequently due to their role in cardiovascular health, while flexibility activities are also recommended multiple times a week to enhance range of motion and prevent injury. Strength activities include a balanced frequency to build muscle safely and effectively.

Overall, while power activities can be beneficial, the recommendation of 1 - 3 days per week for these types of training is more reflective of safe and effective practice for the general population, particularly to avoid overtraining or injuries associated with high-intensity tasks performed too frequently.
