The key objective of the Lief program is to track and train your heart rate variability (HRV) higher to help your nervous system be more resilient to stress. To this end, Lief's patented "HRV autodose" feature makes HRV biofeedback responsive to your body, giving you just the right amount of training to move your HRV biomarkers into a healthy zone. In addition, you have the option to subscribe monthly to a Lief Coach, who can help you stay on track, train your HRV higher, and increase your mindfulness each week.
