electrolytes 75 Hard Is About Grit. Bio-Synergy 75 Is About Results That Last.
Jan 6, 2026
By Daniel Herman
75 Hard is a 75-day mental discipline challenge created by Andy Frisella. It’s less a fitness plan and more a consistency test—miss one rule, you restart at Day 1 .
The 5 non-negotiable rules (every day for 75 days)
1. Two workouts (minimum 45 minutes each)
o One must be outdoors, regardless of weather
o They must be separate sessions
2. Follow a diet
o You choose the diet, but no cheat meals, no alcohol
3. Drink 1 gallon of water (~3.8L)
4. Read 10 pages of a non-fiction / self-development book
o Audiobooks don’t count
5. Take a daily progress photo
What it’s designed to build
Mental toughness & discipline
Routine under pressure
Consistency without negotiation
At Bio-Synergy we love a challenge but for some this may be too much, so we have devised an alternative plan that we feel will deliver great results and most importantly is more accessible and sustainable, providing longer term benefits.
The 6 Bio-Synergy Rules (75 Days)
1️. Train once daily (45–60 minutes)
Strength training 3–4x/week
Conditioning / Zone 2 / mobility on other days
Outdoor movement encouraged , not forced
Restorative days count
Why: Adaptation requires recovery. Progress comes from repeatability.
2. Protein-First Nutrition (no “diet”)
1.6–2.0 g protein/kg bodyweight
Eat 3 meals per day
Ultra-processed food kept minimal
Flexible social meals allowed (max 2/week)
Why: Protein protects lean mass, metabolism, and satiety—especially after 35.
3️. Hydration with purpose
2.5–3L water/day
Add electrolytes if training or sweating
No forced gallon chugging
Why: Hydration should support performance, not become punishment.
4. Sleep & recovery are mandatory
7+ hours sleep target
10 minutes daily of parasympathetic recovery (walking, breathwork, mobility, stretching)
Why: Recovery is the multiplier.
5. Daily knowledge or reflection (10 minutes)
Choose one:
Read (non-fiction)
Journal (training, food, stress)
Learn (podcast / article with notes)
Why: Awareness beats obsession.
6.Weekly proof, not daily pressure
1 weekly progress photo
1 weekly check-in :
Energy
Strength
Sleep
Adherence
Why: Physiology changes weekly—not daily.
