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!

Hey sometimes its just a vibe 🤷

Realistically though, a solid workout can take anywhere from 30 minutes, to a little over an hour

For most of us, anything over 1.5 hours is more socializing than it is training, which is totally ok too

I've been working with Nat for quite some time now

The thing about her is she's always trying to better herself in any way she can.

This Spring I convinced her to REALLY step out of her comfort zone and Train for a HYROX style competition. If you don't know what that is, look it up 😅

I wasn't sure she'd go for it, but she didn't question me and got right to work

Natalie has made improvements in various areas across the years, but I could really sense a mental shift within these last 6 months

I'm excited for her to be part of the Performance Series and can't wait to see how things progress for her by this time next year 🔥

Let's all congratulate Nat on kicking ass!
