The dos:

• It is the best practice to walk on the beach, at the dawn, says Mickey Mehta. The air is settled and clear, so you will get more oxygen.
  
• Climbing hills or walking in sand will strengthen your calf muscles.
• Wear anything you are comfortable in. Walking doesn't necessarily require special gear.
• Carry a water bottle and sun cap, if you are walking later in the day.
• Make sure you wear a comfortable pair of flat shoes. High heels are not optimum to walk, since they will stress your back.
  

The don'ts:

• Strictly avoid hard and inclined surfaces. They stress the knees. You can develop injuries later on.
• Avoid rubber and plastic footwear, especially during the heat.
• Don't walk on busy roads or towards getting some work done. Walking for exercising should be done with only that purpose in mind.
• It is not only about the time you spent walking, but also the distance you covered that matters.
