75 Hard Rest Day Rules: Why Your Body Needs One (and the Workaround)
The 75 Hard rest day rule
Andy Frisella's rules: two workouts daily for 75 consecutive days, no exceptions. There are no rest days.
The intention is mental toughness. The biological cost for most women is real — overtraining symptoms typically appear by week 4-6 if both daily workouts are intense.
The active-rest workaround
The legal workaround that most women use:
- Workout 1: structured (lifting, running, class)
- Workout 2: active rest — a 45-minute slow walk, gentle yoga, mobility flow, or recovery swim
This satisfies the rule (both workouts ≥ 45 min, one outdoors) while letting your body recover.
What counts as "active rest"?
- 45-minute slow walk (zone-1 heart rate)
- Restorative yoga or pilates
- Mobility / foam rolling flow (must be 45 min continuous)
- Easy swim or bike ride at conversation pace
- Tai chi
- Hiking at a leisurely pace
What doesn't count:
- 15-minute mobility (not long enough)
- Stretching only (most rules require movement)
- Hot yoga (counts as intense for most people)
Why women need rest days more than men
Female physiology has a different stress-recovery curve:
- Luteal-phase cortisol is naturally higher
- Iron loss during menstruation impairs recovery
- HPA-axis response to back-to-back high-intensity is slower
This isn't an excuse — it's a design constraint that the original 75 Hard rules ignore.
Her 75's rest-day design
Each Her 75 mode handles rest differently:
| Mode | Rest day rule | |---|---| | 75 Soft | 1 rest day per week allowed, no restart | | 75 Medium | No rest days, but one workout can be a walk | | 75 Hard | No rest days (matches Frisella's original) | | Glow Within | 20-min walks only (low-intensity) | | Better Me | 30 min movement, can be anything |
For most women, 75 Soft's weekly rest day produces better outcomes than 75 Hard's no-rest rule — because the body adapts, not collapses.
Warning signs you need a true rest day
If you're noticing 3+ of these, take a real rest day (even if it means restarting strict 75 Hard, or switching to 75 Soft):
- Resting heart rate elevated 5+ bpm from baseline for 3+ days
- Sleep getting worse despite the same routine
- Workouts feeling 30%+ harder than normal
- Strength dropping or stalling
- Period changes (missed, late, lighter than usual)
- Persistent irritability or low mood
- Frequent minor illness
These are early overtraining signals. Ignore at your own risk.
How the Reset 75 app handles recovery
The Reset 75 app's "active rest" tag lets you log a low-intensity workout that satisfies the rule. The app also tracks weekly intensity distribution so you can see if you're overdoing it.
Bottom line
Strict 75 Hard penalizes rest. Most women succeed by either:
- Using active-rest workouts strategically (1-2 per week)
- Choosing 75 Soft instead and taking the weekly rest day
- Switching to 75 Medium where one workout can be a walk

Frequently Asked Questions
Are rest days allowed on 75 Hard?+
No — under Andy Frisella's original rules, both daily workouts are required for all 75 consecutive days. There are no rest days. The Her 75 app's 75 Soft mode is the only intensity that permits a true rest day (one per week).
What counts as a rest day on 75 Hard?+
Nothing counts as a 'rest day' on strict 75 Hard. However, an 'active rest' workout (a 45-minute slow walk, gentle yoga, or mobility flow) satisfies the workout rule while letting your body recover. Most women use this strategy 1-2 times per week.
