Break through the plateau and curate a meaningful, impactful fitness experience with this science-based approach to exercise and wellness over the age of 40.

After 40, the average person loses 7% of lean muscle mass each decade, and performance can drop by up to 5% per year. No matter how much you love your movement practice—whether it's running, pilates, or spin classes—your body isn't responding like it used to in your 20s and 30s; you aren’t getting leaner, faster or stronger. 

You are not alone. The truth is that as we age, we have different needs from our fitness practice, and fitness after 40 is anything but a one-size-fits-all proposition. It’s about learning to curate the right plan for you based on individual factors and normative data.

In The New Fit, fitness coach and former professional athlete Aaron Leventhal offers a clear path forward built on the concepts of connection, education, and progression. Leventhal breaks down popular myths from modern consumer fitness programs, while teaching the science, the reason, the “why” behind exercise.

Based on best practices developed over more than 20 years in the fitness industry and anchored in the latest research on exercise and longevity, this timely book empowers readers of any age to take charge of their own wellness journey, discover their optimal program, and continue to make the adjustments needed to see results into the future.
