The Problem

Your Training Should Know Where You Are

Most training apps treat every day the same. But your body doesn't work that way. Hormonal fluctuations change your energy, recovery capacity, and injury risk daily.

ZonalFit is the first strength training platform that adapts your programming to your hormonal reality, automatically.

Pregnancy

Trimester-aware modifications. ACOG-aligned safety filters. No supine after T1, no high-impact. Extended warmups, conservative loading.

5-phase return to training. Core reconnection before loading. Medical clearance gated. Walking through full programming.

🔥

Perimenopause

Joint-protective programming. Extended recovery windows. Cortisol-aware intensity caps. Heavy compound lifts prioritized for bone density.

📊

Full Body & Split Programs

12-week periodized programs in full body and split formats. Three training levels: Foundation, Sculpt, and Performance. Progressive overload built in.

You've already tried everything.

The apps that don't know you're in perimenopause. The PCOS tracker that charges $90/year and delivers no actual programming. The trainer who pushed more cardio when more cardio was exactly what your body couldn't handle. The doctor who said "park farther away at the grocery store."

None of it was built for your biology.

ZonalFit covers 14 conditions across the full hormonal lifecycle. Menstrual cycle. Pregnancy. Postpartum. Perimenopause. Menopause. PCOS. Endometriosis. GLP-1 medications. Pelvic floor. Contraceptive type. RED-S risk. Hot flash timing. Injury zones. Equipment adaptation.

One platform. Every stage. Built from clinical guidelines, not marketing assumptions.

Your Body Is Not a Business Model.

87% of popular health apps share your data with third parties. 16 period-tracking apps state they may disclose your data to law enforcement. Flo was found by a jury in 2025 to have illegally shared user data with Meta.

Women are defaulting to paper calendars because they don't trust apps with their hormonal data.

ZonalFit was built differently.

We never sell your health data. We never share it with advertisers. We don't store your cycle history. No third-party tracking. Your health information powers your programming and nothing else. You can delete your data at any time.

Tiffany

Postpartum

"I really like the check-ins and structure of a tailored workout to how I'm feeling that day. It in a way, transforms what showing up 100% looks like."

Amber

Founding Member

"I like the app, it's nice that you can adjust the amount of time you have to work out, what equipment you have, and it still manages to build a full workout for you. The how-to videos and descriptions are great, especially when trying a new exercise."

Jordan

"I was paying $70/month for a gym membership with no guidance. Having a tailored experience at home without having to think through what I need to do is a major game changer."
