🤱 Your Body at 8 Weeks Pregnant
🧪 Hormonal Changes Driving Your Symptoms
Your body is producing massive amounts of pregnancy hormones right now:

🏃♀️ Exercise Guide for Active Women
💪 Exercise Guidelines for 8 Weeks Pregnant
The old “140 bpm heart rate rule” has been debunked! Modern guidelines focus on how you feel rather than strict heart rate limits. 🎯
🎯 Safe Exercise Modifications
| Instead of This | Try This | Why the Change |
|---|---|---|
| Box jumps | Step-ups | Reduces fall risk, easier on joints |
| High-intensity burpees | Modified burpees or squats | Prevents blood sugar spikes that cause nausea |
| Heavy deadlifts | Lighter weights, focus on form | Protects loosening ligaments |
| Contact sports | Swimming or prenatal yoga | Eliminates fall and collision risks |
⚡ Rate of Perceived Exertion (RPE) Scale
Use the “talk test” instead of heart rate monitoring:
- Safe zone: You can carry on a conversation
- Moderate zone: You can say a few words between breaths
- Too intense: You can’t speak at all (slow down!)
💧 Hydration and Fueling Strategies
Proper hydration becomes even more critical during pregnancy. Aim for:
- Pre-workout: 8 oz water 30 minutes before
- During exercise: 4-6 oz every 15-20 minutes
- Post-workout: 16-20 oz for every pound lost through sweat
- Daily total: At least 10 cups (80 oz) of fluids
🛑 Stop Exercising If You Experience:
- Vaginal bleeding or fluid leakage
- Chest pain or difficulty breathing
- Dizziness or feeling faint
- Headache or muscle weakness
- Calf pain or swelling
- Uterine contractions
