Here, Reynolds consults experts in a range of fields to share paradigm-shifting findings that were previously only available in academic and medical journals, including:
* 20 minutes of cardio is all you need (and sometimes six minutes is enough)
* Stretching before a workout is counterproductive
* Chocolate milk is better than Gatorade for recovery
Whether you're running ultramarathons or just want to climb the stairs without losing your breath, The First 20 Minutes will show you how to be healthy today and perform better tomorrow.
