0 – 9 months
Babies nap in carriers (or on a mat).
The newborns sleep through the session. If they wake up, you keep going — we just modify around the feed or the contact-nap. No one’s judging.
Strength training for moms—by one of you.
NASM-CPT, pre/postnatal certified coach. I drive to living rooms across Saucon Valley, Center Valley, Coopersburg, and Lower Macungie — and run weekly group classes in Macungie and Allentown. Babies welcome at every session.

The thing every mom asks
Kids welcome. Always. Ages 0–6.
No babysitter needed. No drop-off line. They’re part of the session — and they get to see their mom get strong.
9 months – 3 years
Busy toddlers find entertainment.
Please bring toys or snacks and whatever your toddler needs to keep busy throughout our session.
3 – 6 years
Big kids ‘help’ with reps.
Big kids love to mimic your movements — this is the time to show them the importance of moving your body.
“Mommy, it’s time to go be a strong girl.”

A note from Lexi
Macungie, PA
I'm not training you to bounce back.
I'm training you forward.
I built Babies and Barbells because the Lehigh Valley didn’t have what I needed when I was pregnant with my first — a coach who’d treat me like an athlete who happens to be pregnant, not a fragile thing who happens to want to move.
If you’re tired of being treated like you’re fragile, this is your place. If you want a workout that fits around a fussy baby and a real life, you’re in the right inbox.

Community Classes
Strength training for moms—by one of you.
Hey—I’m Lexi. I know how hard it is to find time for you between feedings and nap schedules. That’s why my Macungie and Allentown classes aren’t just workouts—they’re your social lifeline.
Your newborn watches from the mat, your toddler becomes your favorite “dumbbell,” and you get to move again. We focus on rebuilding core strength and confidence, all while your little ones play safely nearby. No childcare stress, just progress.

Personalized Training
Private training that comes to you.
Prefer your living room to a gym? Me too. I drive to Saucon Valley, Center Valley, Coopersburg, Lower Macungie, Salisbury Township, and Bethlehem Township — bringing the mat, dumbbells, kettlebells, and bands. Setup is under 90 seconds. Your kids stay in your sightline.
Whether you’re prepping for birth, recovering postpartum, or rebuilding strength, we build an individualized program that’s 100% about your body. No childcare stress, just progress on your terms.

From my camera roll
Real moms. Real workouts. Real coffee after.
Sweaty selfies and snuggle breaks. Toddlers on mats, babies in arms. The room. The actual people.
Honest comparison · who this is for
Babies and Barbells isn't for everyone — and that's the point.
Not me
What I'm not.
“Mommy yoga”
Stretching is great. It's not strength. You won't carry a 30-lb toddler with confidence from a downward dog.
“Bounce-back” Instagram fitness
Promises a pre-baby body in 6 weeks. Ignores diastasis. Sells you a $400 PDF and a body-shame complex.
Yes — this is me
What I am.
Program paced to your specific body's needs
Programming shaped to your stage and your body. The only one like it in the Lehigh Valley.
Real strength training
Dumbbells, kettlebells, barbells where appropriate. Modified per trimester or postpartum stage.
Honest about pace
Postpartum is a year, not 6 weeks. Pregnancy is a build, not a hold. Both get programmed accordingly.
Translation
I’m a real coach, in a real room (or your real living room), for moms who want real strength.

The receipts · From the founder
Four things that don't fit on a price card.
What “NASM-certified” actually means when Lexi shows up for your first session. Four pillars, four receipts, all verifiable.
I.On credentials
Two real certs.
Current. Verifiable.
NASM-CPT + Pre/Postnatal Certified.
Personal-training credential through NASM, plus a separate pregnancy and postpartum certification through a different organization. Continuing-ed every two years on both.
See both certsII.On trust
Fully insured.
COI on request.
Full liability + certificate of insurance.
Professional and general liability for every in-home session. Certificate of insurance sent before your first visit if your building or HOA needs it on file.
III.On the session
She brings the gym.
Setup: 90 seconds.
Mat, dumbbells, kettlebell, bands.
Drives to your living room, garage, backyard, or local park. The kid-safe zone sits next to the mat. You stay in the house. Your baby stays in your sightline.
IV.On lived experience
Two pregnancies.
Two recoveries.
Mom of two — recently.
There's a difference between a coach who's read about diastasis and a coach who's checked her own. Both pregnancies, both postpartum recoveries, in the same Lehigh Valley body now coaching yours.
None of this is on the price card.

“Postpartum I was very self conscious about my body and wasn't sure where to start. Lexi held some personal training classes for me in the comfort of my home. Not only did I lose 20 lbs but I felt stronger all while bonding with my newborn. The class difficulty is for all levels and can easily be modified for re-beginners like me. I would recommend these wor…”

FAQs from the DMs
The five most-asked.
Mom · asked
Is barbell training safe during pregnancy?
2:10 PM
Lexi · replied
Yes — with OB clearance and the right modifications. The pre/postnatal certification I hold exists for exactly this. We don't max out, we don't do supine work after 20 weeks, and load is adjusted by trimester. Most clients keep training until 38-40 weeks.
2:11 PM
Mom · asked
Do you check for diastasis recti? What about pelvic floor?
2:11 PM
Lexi · replied
If you feel your abdominal separation is hindering your movement, we can check you and create a plan to still build strength. If anything flags outside my scope, I refer you to a local pelvic-floor PT.
2:12 PM
Mom · asked
Do you train in-home in Saucon Valley, Center Valley, and Coopersburg?
2:12 PM
Lexi · replied
Yes. I drive to your living room across Saucon Valley, Center Valley, Coopersburg, Lower Macungie, Salisbury Township, Bethlehem Township, and Emmaus. I bring the mat, dumbbells, kettlebells, and bands — setup is under 90 seconds.
2:13 PM
Mom · asked
What if my baby cries the whole session?
2:13 PM
Lexi · replied
Totally expected. Step away to soothe, feed, snuggle — and rejoin whenever. Babies welcome newborn through age 6, in both Macungie/Allentown group classes and in-home 1-on-1 sessions. No babysitter needed.
