NASS FIT / Trimester 3

Welcome to Your Third Trimester

You’re entering the final chapter of pregnancy. Your baby is growing rapidly, and every week brings you one step closer to meeting your little one.

You may notice that everyday movements require more effort, your energy changes from day to day, and comfort becomes just as important as fitness.

This is no longer about pushing harder. It’s about preparing smarter — so you can feel stronger, move more comfortably, and approach birth with confidence.

This guide is for general wellness and educational purposes and is not medical advice. Always consult your healthcare provider before beginning any exercise program during pregnancy.

What’s Happening With Your Baby

Your baby continues gaining weight and storing healthy body fat. The lungs and brain are developing rapidly.

Movements may feel stronger but become less dramatic as space inside the uterus becomes more limited.

Your baby is preparing for life
outside the womb.

Preparing for Birth
Starts Now

Many women think birth preparation begins when labor starts. In reality, it begins weeks before.

The way you breathe. The way you move. The way you strengthen your body. The way you recover. All of these habits can help you feel more prepared for birth.

💪The goal isn’t to control labor. It’s to help your body feel capable, supported, and ready.

Weekly Wellness Checklist

NASS FIT / Trimester 3

Did You Know?

Your breathing changes as your baby grows. As your uterus expands, your diaphragm has less room to move. Learning efficient breathing patterns can help you feel more comfortable during pregnancy and may become a valuable tool during labor.

Mobility and stability work together. Preparing for birth isn’t just about becoming more flexible — it’s about moving with control, confidence, and awareness.

Questions
We Hear Most

Should I keep exercising?

In many healthy pregnancies, staying active during the third trimester can help support comfort, mobility, and overall well-being. Your routine should always reflect how your body feels and your provider’s recommendations.

Why do simple movements feel harder?

As your baby grows, your center of gravity shifts, your joints become more mobile, and everyday activities require more energy. This is a normal part of pregnancy.

What if I feel tired again?

Many women notice that energy levels decrease during the final weeks. Listen to your body, adjust your activity, and remember that rest is part of preparing for birth.
