Tips & Guide
Understanding Exercise Fatigue vs. Muscle Strain
| Aspect | Build 41 - Exercise Fatigue | Build 42 - Muscle Strain |
|---|---|---|
| What triggers it | Only deliberate exercises (player-triggered workouts via menu) | All strenuous activities: combat swings, running, heavy loads, bad sleep, and exercises |
| When it occurs | Delayed onset (~12 hours after exercise) | Gradual/immediate onset - strain builds as you exert |
| Affected areas | Depends on exercise: arms (push-ups), legs (squats), etc. | Specific to used body part: arms (weapon usage), legs (running, stomping), etc. |
| Duration | Generally wears off after ~1 day naturally | Varies by severity - frequent short rests can reduce it |
| Mitigation | Only exercise when safe; use painkillers; schedule sleep through pain | Character build (high strength, skills), use lighter gear, pace yourself |
Top 10 Tips for Managing Fatigue & Strain
- Secure a Safe Training Environment - Don't exercise when zombies are nearby.
- Start Slow with Gradual Progression - Begin with short sessions to build regularity.
- Alternate Days & Muscle Groups - Don't work the same muscles two days in a row.
- Maintain a Healthy Weight - Being underweight or overweight penalizes your fitness XP gains.
- Eat for Performance - High protein diets increase strength XP gains by up to 50%.
- Use Books and Entertainment - Watch exercise VHS tapes to gain regularity faster.
- Plan Your Recovery - Schedule workouts so you'll sleep through the worst pain.
- Know When to Stop - Listen to your body and don't push too hard.
- Use the Environment - In Build 42, alternate attacks (swing vs. stomp) to distribute strain.
- Rest is Productive - Sitting on furniture or ground accelerates recovery.
Exercise XP Table

Build 42 Combat Tips
- Focus on one weapon type to level it faster and reduce strain.
- Use lighter weapons initially as they cause less strain per attack.
- Mix up attacks - alternate between swinging, pushing, and stomping.
- Take breaks during fights if possible to reduce strain accumulation.
- Consider character traits like Strong or Athletic to reduce strain effects.
- Carry painkillers for emergency situations when you must fight while sore.
- Remember: High weapon skill reduces strain accumulation during combat.
