What are some alternatives to meditation having the same benefits?
That depends on what specific benefits you're looking for.

If you're trying to achieve mindfulness, there are exercises you can do throughout the day to remind you to take a second and be aware of your surroundings and to examine how you feel and what you're experiencing. A regularly vibrating watch, tapping your palms, or a habit to practice mindfulness whenever a trigger/event happens throughout the day might give you similar benefits to practicing mindfulness during a dedicated meditation session.

On the other hand if you're trying to relax or prepare yourself for a busy day, or to get yourself ready to sleep, activities like yoga have been known to help exercise your body and your mind at the same time.

There are many reasons why people meditate. Do you have more information about what benefits you'd like to focus on?
