For clients with high blood pressure, it is recommended to engage in regular exercise and to control stress through physical activity or relaxation techniques.
Step-by-step explanation:
When training a client with high blood pressure, it is crucial to recommend lifestyle changes that can help manage and lower their blood pressure to reduce the risk of cardiovascular diseases. The first recommendation is to encourage regular exercise, which can be performed five days a week for at least 30 minutes to help lower blood pressure, improve heart health, and assist with weight management. Secondly, it's important to advise on stress control, as stress can elevate blood pressure; techniques such as breathing exercises, brisk walking, or other forms of physical activity can be beneficial in managing stress levels.
