STOP buying these at Sam’s Club… and try these swaps instead 👀

Fat loss doesn’t mean you have to completely change the foods you enjoy. Sometimes a few smarter swaps can make hitting your goals WAY easier.

The foods with the ✅ can help you:
🔥 Get more food for fewer calories
💪 Increase your daily protein
🍿 Still eat snacks and foods you actually enjoy
📉 Create a calorie deficit without feeling like you’re constantly dieting

Something as simple as choosing a 150–160 calorie snack with 15–17g of protein can give you a lot more bang for your calorie buck than a typical snack that provides little protein.

You don’t need a “perfect” grocery cart.

You just need enough small decisions that move you toward your goal.

Save this for your next Sam’s Club trip 👊

What store should I do next?

I love all of my clients, but this one takes the cake. Wedding Cake that is!

Olivia and I really got close competing in High School Track and we rekindle that relationship in College, at the Gym of all places

Since having kids she has started putting a lot more attention on her own heath and tapping into that competitive mindset again.

I remember in the winter showing her a video of a HYROX competition thinking she would just brush it off but she was fired up about it

She then willingly signed up for my HYROX style training program and has been really kicking ass at another level ever since

I'm proud of the work you put in, and can't wait to signup for an official HYROX Partners Race with you ❤️

Let's show Olivia some Love on her transformation!

All jokes aside, its good to talk about what's bothering you

The gym is a great place to get rid of frustration and anxiety by burning up your extra energy. I love getting a good workout in before a big social event, flying on a plane, a podcast, or even meeting a potential new client

Our bodies are designed to move

It's up to us to keep them moving

Last Saturday we tried the popular Hero WOD, Cindy

Tom Holland recently talked about how this is the workout he focused on to get jacked for the new Spiderman movie

Each round is
5 Pullups
10 Pushups
15 Air Squats

The goal is to get as many rounds in as possible in 20 minutes

Our Results
Me: 19 rounds
Olivia: 12 rounds
Sam: 15 rounds

Tom's best is 27 rounds 😅

Try this out and let me know how many rounds you were able to get in!
