Cooling down after your workout allows for a gradual recovery of preexercise heart rate and blood pressure.
The answer to your question is: A) Your food journal.
It's best to use a food journal to keep track of the things you've eaten, and how much calories you've eaten throughout that day. Using a journal can help you when your on a diet so you can keep track of what you've been eating.
I hope this helps you!
Have a wonderful day!
