Happy Birthday to the heart and soul behind CORE, Dr. Sarah “Sassy” Weinstein! 💛

CORE is so much more than a practice. It’s a reflection of your passion for helping people feel stronger, move better, and live healthier lives. Your energy, compassion, and genuine care for every person who walks through the door are what make this place so special.

Here’s to another year of doing what you love, making an impact, and hopefully taking a little time to celebrate YOU today. 🎉

And the clock just reset, again… ⚡️⛈️ ⏰

Always keep a few easy snacks on hand for those “we’re gonna be here a while” moments 😂 — sports sidelines, travel days, or the inevitable lightning delay.

My go-tos:
🥑 Cut-up veggies + avocado or hummus. Love Good Foods avo mash for making life more convenient.
⚡️ Protein bites/energy balls
🍎 Apple slices
🥜 Nuts
🍓 Dried fruit
☕️ A small bite of Quantum Energy Square for an extra boost

The goal: protein + healthy fats + fiber + carbs to keep you fueled and avoid the “I’m starving, I’ll eat anything” moment. 😂

Thanks for listening! Catch you at the next game 🏈

Friday reminder from your sports med doc: movement does not have to be a whole production. 😄

You don’t always need a 45-minute workout, a matching set, the perfect playlist, and a trip to the gym for it to count (though I do love all of these as well).

Here’s the cool part: your body benefits from movement whether it happens all at once or in little pockets throughout the day.

They’re called movement snacks...and I’m always here for a good snack. 😉

✨ Calf raises while brushing your teeth.
✨ Sit-to-stands before your next email.
✨ Walk while you’re on a phone call.
✨ Park a little farther away.
✨ Stretch while the coffee brews.

One thing I’ve learned as a sports medicine physician is that the best movement routine isn’t the “perfect” one—it’s the one you’ll actually do. That’s where the magic happens.

So heading into the weekend, don’t overthink it. Sneak movement into your day however you can and call it a win. It all adds up.

What’s one movement snack you’ll try this weekend? 👇

Postpartum workouts have looked...different. 😂

Most weekdays my alarm goes off at 5 AM so I can sneak in a workout before anyone else is awake. I’m definitely tired when I roll out of bed, and I question the decision for about the first 10 minutes, knowing it would be so easy to just close my eyes again (which also happens!). But those quiet minutes to myself are worth it every single time, and I always feel better afterward.

Other days I try to work out in the middle of the day when I’m home. In theory, great idea. In reality? It usually means stopping to feed or hold the baby, help one of the big kids, answer “Mom!” fifteen times, or just hit pause because someone needs me. A 30-minute workout somehow takes an hour...if I even finish it.

Every day looks different. Some workouts are uninterrupted. Some are chopped into pieces. Some don’t happen at all.

And honestly? That’s just the season I’m in right now.

I’m not chasing perfect workouts. I’m just trying to keep showing up when I can, because moving my body helps me feel like me again. At 9 weeks, still focusing heavily on deep core work and pelvic floor engagement, but excited to finally add some weights in this week!

If you’re in the postpartum season too, I’d love to know...what do your workouts actually look like these days?

Your first prescription today? Sunlight + steps. ☀️🚶‍♀️

Getting outside first thing does more than wake you up — it’s setting your body’s clocks for the whole day:

🔹 Circadian clock — morning light anchors your internal rhythm, meaning better sleep tonight and sharper focus today
🔹 Cortisol rhythm — light exposure supports a healthy cortisol curve: a sharp rise at wake-up, then a steady decline — the pattern your mood and energy depend on
🔹 Insulin sensitivity — even a 10-minute walk after waking can improve glucose regulation for hours (stacks even more if you walk after meals too)

No prescription pad. No sunglasses (unless you have sensitive eyes like me 😎). Just outside, before 9am.

This isn’t a workout — it’s a daily vitals check for your metabolism and your mind.

To all of you amazing postpartum moms, let’s talk about what your body is actually doing right now.

Healing tissue.
Making milk.
Recovering from pregnancy and birth.
Doing all of it on broken sleep.

That’s a lot of physical work — and physical work needs fuel.

As a sports and lifestyle medicine physician, I look at postpartum recovery the same way I’d look at recovery from any major physical event: your body heals and adapts better when it’s properly nourished. Protein is one of the biggest levers here, especially if you’re breastfeeding or getting back to movement.

A general target many experts recommend is around 1.2–1.6g of protein per kilogram of body weight per day postpartum. But — and I say this as a mom of 3, not just a doctor — you do not need to weigh, track, or overhaul your entire diet to get there.

You just need protein easy to reach for. Here’s what’s in my rotation right now:

✔ Greek yogurt (~17–20g per cup)
✔ Cottage cheese — filling, versatile, way better than you remember from childhood
✔ Egg muffins or frittata — prep once, grab all week
✔ Energy balls (recipe in a past post!)
✔ Edamame — weirdly addictive, high protein snack
✔ A protein shake, for the days when “realistic” beats “ideal”

My rule for myself: include a quality protein source at every meal or snack. Not perfectly. Just consistently.

That one shift adds up more than people expect!

I’m filming this the day of my own 6-week visit.

“Cleared” ≠ “ready” — and as a sports med physician living it in real time, here’s the difference that actually matters.

Save this for the friend who’s being too hard on herself. 👇

101°F in NJ today. Your body doesn’t care if you’re running a 10K or walking the dog. 🥵

Here’s what actually matters for staying hydrated and cool — athlete or not.

1.⁠ ⁠Don’t wait until you’re thirsty
Thirst means you’re already 1-2% dehydrated — enough to affect performance and focus (ACSM). Sip all day, not just during workouts.

2.⁠ ⁠Check your p*e, not your gut
Pale yellow = good. Dark = drink more. Clear = you might be overdoing it (hyponatremia is real).

3.⁠ ⁠Sodium matters, not just water
Heavy sweat sessions in this heat = electrolyte loss too. If you’re out 60+ min or soaking your shirt, add an electrolyte source (NATA guidelines).

4.⁠ ⁠Weigh in before and after exercise
Gold standard for knowing exactly what you lost. Replace every pound with ~20-24 oz of fluid (ACSM).

5.⁠ ⁠Cooling is half the battle
Morning/evening workouts, shade, a cool towel on the neck — you can’t out-drink a heat stress problem.

Warning signs: thirst, fatigue, headache, dark urine, muscle cramps, rapid heartbeat
Heat stroke = 911, not “drink water”: confusion, hot/dry skin, no sweating, fainting

Stay smart out there today. 💧
