About us
Peter and Yenni Herschelman. Who we are, what changed, and the scans behind it.
Who we are
Peter
I’m Peter — husband, dad to a baby girl, and a Lincoln local. My wife’s as obsessed with biohacking and longevity as I am.
Aspire Health is the two of us, out of Lincoln, California. Yenni runs the women’s side; the rest is mine.
What changed
- Lifting hard, with someone who pushed me
- Fixing my food, which meant counting calories
- Trying supplements myself until I knew what was worth taking
- Making the most of my sleep, newborn nights included
Individual results vary.
Yenni
I’m Yenni — Peter’s wife, and I run the women’s side of Aspire Health.
Our daughter was born in September 2025. I started lifting with progressive overload while I was pregnant.
My before photos are from November 2025, two months postpartum, so they include the body fat a pregnancy adds. My afters are from July 2026.
What changed
- Progressive overload: lifting a little more over time
- Counting calories
- Solid supplementation
- Creatine, for the first time
Individual results vary.
