Leah Jantzen is a self-help author, speaker, triathlete and performance coach living on Long Island. Leah is a firm believer in the infinite potential residing in every one of us, and has dedicated her life to helping others realize it.

The creator of Train Your Brain—a system for boosting mental fitness—Leah instructs her clients to clearly see an athletic goal in their mind, then guides them through the process of training their bodies to achieve that goal, utilizing the same principles she used to build a successful business.

“At any given time, two of these facets of the self are prioritized while the third takes a back seat,” Leah explains. “For most of us, those are the family and career facets. That’s normal, but if you’re going to find balance and pursue the third facet with all your dreams and goals, then you need tools to block out distractions—to weed out anything non-essential in your life.”

The discipline and mental toughness required to root out trivial nonsense can be developed—if you know how to train your mind.

Proving the maxim that it’s never too late to chase your dreams, Leah ran her first marathon at the age of 42. Upon crossing the finish line, the mother of four was immediately hooked, spring-boarding from one marathon to the next, and going on to compete in triathlons. After consistently finishing in the top 2% of her age group, she ultimately qualified for the Iron Man World Championships in Kona, Hawaii in 2020, an unthinkable feat just a few short years ago.

“If you can combine visualization, action, and positivity, then there’s really nothing that’s off-limits,” says Leah. “But even as a long-time believer in this principle, I subconsciously allowed self-limiting beliefs to creep into my psyche. Identifying those beliefs, figuring out why they were there, and then proving them to be untrue is one of the most immensely satisfying experiences of my life. Everyone has these limiting beliefs, and I want everyone whose life I touch to experience that same incredible feeling of overcoming them—and realizing that they’re capable of anything.”
