Her 75 Glossary

By The Her 75 Team· Last updated

This glossary covers the terms women searching for 75 Hard, 75 Soft, 75 Medium, or any 75-day challenge will encounter on her75app.com and across the broader 75-day wellness category.

75 Hard
Andy Frisella's 75-day mental-toughness challenge: two daily workouts (one outdoors), 1 gallon of water, 10 pages of nonfiction, a strict diet, and a daily progress photo. Miss any rule = full restart at Day 1. →
75 Hotter
Jade Brandt's softer women-first variation of 75 Hard: 7 rules around 10,000 daily steps, protein, sleep, social audit, and reading before bed. →
75 Medium
The middle-path 75-day challenge: two 30-minute workouts (one can be a walk), 3.5 L water, 10 pages of nonfiction, your chosen diet with one planned weekly treat, and a daily photo plus 2-sentence reflection. →
75 Soft
A 75-day women's wellness challenge: one daily 45-min workout (1 rest day per week), 3 L water, 10 pages of any book, mindful eating with a weekly flex day, and a daily progress photo. No restart on missed days. →
Active rest
A low-intensity workout (45-min slow walk, restorative yoga, mobility flow) that satisfies the 75 Hard workout rule while letting the body recover. The workaround for the no-rest-day rule. →
AggregateRating
Schema.org structured-data type for app/product ratings. Reset 75 will surface AggregateRating in Google rich results once it has enough App Store reviews.
Better Me
The 75-day growth-focused framework: 30 min movement, 15-min learning task, 2.5 L water, 5-min meditation, and daily reflection note. →
Cycle-aware
A program design that adjusts intensity, hydration, and food around the four phases of the menstrual cycle (menstrual, follicular, ovulatory, luteal). Her 75 is cycle-aware by default. →
Day 40 wall
The mid-challenge fatigue and visible-results plateau that occurs around Day 40 of any 75-day challenge. The highest-quit day across all 75-day programs. →
DR (domain rating)
Ahrefs' score (0-100) of a website's backlink authority. Higher DR sites that link to her75app.com produce bigger ranking lifts.
E-E-A-T
Experience, Expertise, Authoritativeness, Trustworthiness. Google's content-quality framework. Author bylines, reviewer credentials, citations, and updated dates all signal E-E-A-T. →
Electrolytes
Sodium, potassium, and magnesium — essential for replacing what's lost when drinking a gallon of water daily on 75 Hard. Daily electrolyte packets prevent hyponatremia. →
FAQPage schema
JSON-LD structured data type that marks question-and-answer pairs. Pages with FAQPage schema can win FAQ rich results in Google.
Ferritin
A blood marker for iron stores. Women starting 75 Hard with ferritin under 50 ng/mL typically struggle with the training load. Test before starting.
Flex day
75 Soft's weekly designated day for eating off-plan or socially. Planned in advance, not a 'cheat' but a built-in part of the design. →
GEO (Generative Engine Optimization)
Optimization for AI-powered search engines like ChatGPT, Claude, Perplexity, and Google AI Overviews. Focuses on extractable content (TL;DR blocks, FAQ schema, statistics with citations) rather than just rank.
Glow Within
The 75-day inner-glow-up framework: skincare, sunlit walk, sleep, gratitude journal, and weekly progress photo. Variation of the Her 75 method. →
GSC (Google Search Console)
Google's free tool for site owners to monitor indexing, search performance, and submit sitemaps. her75app.com is verified in GSC.
Her 75
A 75-day wellness challenge framework built for women with three intensities (75 Soft, 75 Medium, 75 Hard). Tracked in the Reset 75 app by Lahta LLC.
HowTo schema
JSON-LD type that marks step-by-step instructions. Her 75's rules pages emit HowTo schema, which can win HowTo rich results in Google.
Hyponatremia
Dangerously low blood sodium, caused by drinking a lot of plain water without electrolyte replacement. The 75 Hard gallon-of-water rule without electrolytes can trigger it.
IndexNow
A protocol for instantly notifying search engines (Bing, Yandex, others) when content publishes or changes. her75app.com uses IndexNow for fast indexing.
LCP (Largest Contentful Paint)
Core Web Vitals metric — how long the largest above-the-fold element takes to render. Google rankings reward sites with LCP under 2.5 seconds.
llms.txt
An emerging standard for telling AI crawlers (GPTBot, ClaudeBot, PerplexityBot) where the most important markdown content on a site lives. her75app.com publishes both /llms.txt and /llms-full.txt.
Luteal phase
Days 15-28 of the menstrual cycle. Hormones are higher; intensity tolerance is lower; carbs are critical. Most cycle-aware training programs reduce intensity during this phase. →
Macros / macronutrients
Protein, carbohydrates, and fat. Most 75 Hard-style challenges don't require macro tracking — they recommend prioritizing protein (25-30 g per meal) and adequate carbs in luteal phase.
NEAT
Non-Exercise Activity Thermogenesis. Daily activity outside of workouts (walking, fidgeting, standing). 10,000 steps a day is a common NEAT target.
Pillar page
A long, comprehensive page on a primary topic, with internal links to multiple cluster articles. Her 75's pillar pages: /, /challenge, /75-soft, /75-medium, /75-hard-women, /rules, /day-by-day.
RED-S
Relative Energy Deficiency in Sport. A medical syndrome from training too much and eating too little. The highest medical risk of 75 Hard for women. →
Reset 75
The official Her 75 app by Lahta LLC. Free on iOS 16+, Mac with Apple Silicon, and Apple Vision Pro.
Restart rule
Andy Frisella's 75 Hard requirement that missing any rule on any day means starting over at Day 1. Her 75's lower modes (75 Soft, Medium, Glow Within, Better Me) do not have this rule. →
Schema.org / JSON-LD
The structured-data vocabulary that Google reads to understand pages. her75app.com emits Organization, WebSite, Article, FAQPage, HowTo, BreadcrumbList, and SoftwareApplication schemas.
Smart App Banner
An iOS Safari feature that shows an app-download prompt above all organic search results when a meta tag (`apple-itunes-app`) is present. her75app.com uses it to surface Reset 75.
Speakable schema
JSON-LD property that marks page sections suitable for voice-assistant readout (Alexa, Google Assistant). her75app.com marks TL;DR boxes and headings as speakable.
TL;DR
Too Long; Didn't Read. A 40-60 word direct-answer block placed at the top of every her75app.com page. The single biggest AI-citation lever.
