Benefits of Working Out While Pregnant

• Supports healthy weight gain – helps manage weight within recommended ranges
• Improves circulation – lowers risk of swelling, varicose veins, and blood clots
• Reduces back pain & aches – strengthens muscles that support posture and your growing belly
• Boosts endurance for labor – better stamina and strength can make delivery smoother
• Helps with recovery – active moms often return to pre-pregnancy strength faster

• Improves core & pelvic floor strength – may reduce incontinence and help with pushing during labor
• Supports fetal brain health – research shows potential neurological benefits
• Lowers risk of childhood obesity – linked to mom’s healthy metabolism

And honestly, the list could go on.

Tips for Working Out Safely During Pregnancy

If you’re joining a fitness class at Sweat Fixx, here’s what we recommend during your pregnancy journey:

1. Don’t be afraid to lift weights but this is not a time for PRs – Strength training supports your body as it carries a growing belly and can ease back pain. Stick to the weights you used pre-pregnancy, but skip chasing new personal records. No personal bests for deadlifting right now!
2. Focus on breathing – A lot of pelvic floor issues stem from improper breathing. Never hold your breath while lifting (like during squats). Exhale through the hardest part of the movement to protect your pelvic floor.
3. Watch for coning – As pregnancy progresses, coning can show up in the core, especially during planks. We always provide modifications (like marches or side planks) so you can safely train.
4. Check in with a Pelvic Floor PT – Working with a pelvic floor specialist can be a game-changer. At FIXXED, our PTs help clients adjust lifts, breathing, and core strategies throughout pregnancy to support both pregnancy and delivery. You can even book a free 15-minute consult to see if it’s the right time to start.
