100% agree!

I love knowing that physical fitness will improve my mental and spiritual health. That's an easy win. I go for a relaxing run in the mountains in the morning and my mind and spirit are boosted for the day.

Tony Robbins (I'm a big fan) will tell you that psychology is 80% of life but the most important thing you'll need to live a great life is fantastic physical health.

You can not separate the two.
