PATENT PENDING The first strength training platform built for female biology
Conditions We Support

9 conditions. Training built around your biology.

Not a one-size-fits-all approach. Every condition gets its own programming logic.

Menstrual Cycle

5 cycle phases. Daily-adaptive, not calendar-predicted.

Symptom-responsive cycle-aware training. Daily check-in reads sleep, energy, cramps, bleeding, and mood, then adapts the session accordingly. Based on the research showing group-level cycle-phase effects on performance are trivial (McNulty 2020; Colenso-Semple 2023). What actually matters is what your body is doing today, not a calendar prediction.

PCOS

10–15% of reproductive-age women.

Polycystic ovary syndrome affects 10-15% of reproductive-age women and changes how the body responds to training. Our PCOS engine adapts training frequency and intensity to support insulin sensitivity, with recovery windows that account for the hormonal disruption PCOS creates. Programming is layered on top of cycle-phase awareness when applicable.

Endometriosis

Flare-aware. Not a fixed protocol.

Endometriosis requires programming that adapts to flare severity, not a fixed protocol. Flare-day mode drops to restorative work automatically. Pelvic floor muscle training is integrated throughout, supported by recent RCT evidence (Del Forno 2023; Gabrielsen 2025). We support training in the presence of endometriosis. We don't treat the disease itself.

Pregnancy

Trimester-aware. ACOG-aligned.

Trimester-aware modifications aligned with ACOG Committee Opinion 804 (2020), the 2019 Canadian guideline (Mottola et al.), WHO 2020, and the 2025 BJSM resistance-training-in-pregnancy meta-analysis (Prevett et al.). Evidence-based programming, not anxiety-driven avoidance. Every exercise filters through pregnancy safety logic before it reaches your session.

Postpartum

Five-phase return. Medical clearance gated.

Five-phase return to training, not a single "6 weeks and go" cutoff. Phase 0 (0-6 weeks): walking only. Phase 1 (6-12 weeks): bodyweight, core reconnection. Phase 2 through Phase 4: progressive loading back to full programming. Medical clearance gated at each transition. Pelvic floor integration throughout.

Perimenopause

Heavier loads. Not less intensity.

The fitness industry tells perimenopausal women to "take it easy." The research says the opposite. Our perimenopause engine prioritizes heavy compound lifts for bone density preservation, with extended recovery windows and cortisol-aware intensity caps. Joint-protective exercise selection. Higher intensity, smarter recovery.

Menopause

Bone density focused. Fall-prevention integrated.

Post-menopausal women need heavier loading, not lighter. Our menopause programming prioritizes 80-85% 1RM compound lifts with 3-5 rep ranges and longer rest periods. Bone density preservation, sarcopenia prevention, and fall-risk reduction are built into every session. This is strength training that treats menopause as a training context, not a limitation.

GLP-1 Medications

Muscle preservation protocols on semaglutide and tirzepatide.

Women on semaglutide, tirzepatide, and similar GLP-1 receptor agonists face accelerated muscle loss alongside fat loss. Our GLP-1 protocols prioritize muscle preservation through appropriate training volume and intensity, adapted for common medication side effects including fatigue, nausea, and reduced appetite.

Celiac Disease

Flare-day mode after gluten exposure.

Celiac disease is an autoimmune condition that drives malabsorption, chronic low-grade inflammation, and elevated osteoporosis risk. Our celiac engine scales sessions on flare days (after a gluten exposure), prioritizes bone-loading compound lifts calibrated to celiac BMD risk, and compounds adaptations when perimenopause overlaps. Diet is not the only adaptation. Training has to respect the condition too.

On the Roadmap

What's Coming Next

Our condition engine is designed for expansion.

Hypothyroidism

Training adaptations for metabolic and energy disruptions caused by thyroid conditions.

Cancer Survivors

Return-to-exercise protocols for women post-treatment, developed with clinical input.

Pelvic Floor Dysfunction

Expanded pelvic floor integration beyond pregnancy and endometriosis contexts.

Your Condition Shouldn't Limit Your Training

It should inform it. That's what ZonalFit does.
