Self-help ✦ Penny’s Take
Heart Breath Mind
Leah Lagos · 2020
82/100
👍 Worth It
Dr. Lagos builds her 10-week HRV program on genuine clinical research with elite performers, and the breathing-plus-CBT pairing is more rigorous than most stress books dare to be. The upfront science is dense but pays off once readers reach the protocol. A standout in the evidence-based wellness space.
