Final answer:
An effective cool-down after strength training includes 5-10 minutes of low-intensity walking or stretching. High-intensity walking may not be suitable for a cool-down as it can hinder recovery and increase the risk of injury.
Step-by-step explanation:
An effective cool-down after a strength training session is important to allow your body to gradually transition from exercise to rest. One option for a cool-down is 5-10 minutes of low-intensity walking. This helps to gradually lower your heart rate and blood pressure, allowing your muscles to relax and prevent lightheadedness or dizziness.
Another option mentioned in the given choices is 5-10 minutes of high-intensity walking. However, it is important to note that high-intensity exercise may not be suitable for a cool-down after strength training, as it can hinder the recovery process and increase the risk of injury.
Stretching after strength training is also beneficial, but it should be done after the cool-down. Stretching helps to improve flexibility, reduce muscle tension, and prevent muscle soreness.
