Introduction: Why Weight Gain in Pregnancy Causes So Much Stress
If you’ve found yourself Googling “How much weight should I gain during pregnancy?” or feeling unsure about how your changing body fits into your fitness routine, you’re not alone. Weight gain is one of the most searched — and most emotionally charged — topics during pregnancy.
At Knocked‑Up Fitness®, we believe weight gain during pregnancy isn’t something to fear or control — it’s something to support intelligently. When approached with the right mindset and movement strategy, weight gain can be a sign that your body is adapting exactly as it should.
What’s Considered “Healthy” Pregnancy Weight Gain?
While every pregnancy is unique, medical guidelines provide general ranges based on your pre‑pregnancy BMI. These numbers are guidelines, not rules — and they don’t account for muscle mass, genetics, or overall health. This is very important to understand…they don’t account for muscle mass, genetics, or overall health.
Instead of focusing on a specific number, it’s more helpful to ask:
Is my body feeling supported?
Am I fueling and moving in ways that reduce pain and improve function?
Do I feel strong, mobile, and connected to my breath?
Why Weight Gain Is Essential (and Protective)
Pregnancy weight gain supports:
Baby’s growth and development
Increased blood volume
Placenta and amniotic fluid
Hormonal shifts
Changes in posture and balance
Trying to restrict or “manage” weight gain through excessive exercise or under‑fueling can actually increase discomfort, fatigue, pelvic floor dysfunction, and injury risk.
The Role of Fitness During Pregnancy (It’s Not About Burning Calories)
One of the biggest misconceptions is that prenatal exercise is meant to control weight gain. In reality, the goal of pregnancy fitness is to:
Support posture as your center of gravity shifts
Maintain functional strength for daily life
Reduce back, hip, and pelvic pain
Improve circulation and energy
Prepare your body for birth and recovery
At Knocked‑Up Fitness®, we take this one step further by teaching you how to move well as your body changes — not just that you should move. Our approach emphasizes better use and support of your deep core and pelvic floor, so movement feels more stable, efficient, and connected as pregnancy progresses.
This is also where our Push Prep Method comes in. Rather than waiting until labor to think about pushing, we intentionally prepare the body during pregnancy by teaching:
How to coordinate breath with the deep core and pelvic floor
How to relax and lengthen the pelvic floor (not just strengthen it)
How to generate effective, supported force without bearing down unnecessarily
This preparation helps support a more efficient labor, may help minimize or even prevent tearing, and sets the foundation for faster, more complete postpartum healing.
Strength training during pregnancy, when done correctly, doesn’t fight against weight gain — it helps your body adapt to it, support it, and work with it through pregnancy, birth, and beyond.
How Strength Training Supports Healthy Weight Gain
Prenatal‑appropriate strength training:
Improves muscle balance as joints become more lax
Supports the deep core and pelvic floor
Helps distribute load more efficiently through the body
Encourages confidence and body awareness
This is why we emphasize intentional, functional movement over high‑intensity or appearance‑driven workouts.
Signs You’re Supporting Your Body Well
Instead of tracking weight, look for these positive signs:
You recover well between workouts
Your pain levels are manageable or improving
You feel more stable and supported as your belly grows
Your breathing feels calm and connected during movement
Your core and pelvic floor feel connected and strong
These are far better indicators of a healthy pregnancy than the scale alone.
Common Mistakes Pregnant Mamas Make Around Weight & Fitness
Over‑exercising to “stay small”
Avoiding strength training out of fear
Ignoring core and pelvic floor connection
Comparing weight gain to others
A well‑designed prenatal fitness routine meets your body where it is — trimester by trimester.

Final Thoughts: Trust the Process
Pregnancy weight gain isn’t a problem to solve — it’s a process to support. When you shift the focus from controlling your body to caring for it, fitness becomes a powerful tool for confidence, comfort, and long‑term health.
Your body is doing important work. The goal is to help it do that work well. And yes — you’ve got this, mama!

Frequently Asked Questions About Pregnancy Weight Gain and Exercise
Is it safe to exercise while gaining weight during pregnancy?
Yes. In most healthy pregnancies, exercise is not only safe but beneficial. The key is choosing prenatal-appropriate movement that supports your changing body, deep core, and pelvic floor.
Can strength training help with pregnancy weight gain?
Yes. Strength training during pregnancy helps your body adapt to weight gain by improving posture, joint support, and muscle balance — rather than trying to control or limit weight gain.
Should I exercise if I feel like I’m gaining more weight than expected?
Movement can still be supportive, but it’s important to focus on how you feel rather than the number on the scale. Prenatal fitness should prioritize comfort, function, and preparation for birth — not calorie burn.
How does prenatal exercise help with labor and recovery?
When exercise includes deep core and pelvic floor coordination, it can help prepare your body to push more effectively during labor and support faster postpartum healing.
