Principia CrossFit


Hey guys,
This is a FREE, virtual event, just for fun! Not a true Grueling CrossFit event. Just one workout with three scores. Age division from 14-65+. There are so few opportunities here in Boise to see how you fair against a large group of athletes. Hopefully this simple, quick, and FREE event will help get lots of people involved.
Just signed up! Excited to get started :-)
Pro move!

I think you should require this for every class
Boise area TACPs and supporters mark your calendars, 22 July 2017. The local Idaho ANG recruiters and 2 gyms (CrossFit E3, Eagle ID and Principia CrossFit) have come together to help get a fitness challenge (AMRAP Style) event up and running in an effort to support the TACP Association. Any profit from the event registration donation goes to association. Come out for a workout, come out for a good time.

Being "fit" is hard work.⁠

It takes consistency. It takes education. And it takes effort.⁠

There's a reason so much of our world is out of shape. It's HARD!⁠

Want it to be a little easier? That's where we come in!⁠

At Principia, we understand just how hard it is to make big lifestyle changes. And we know just how important it is to long term health!⁠

We work with our clients to find the lowest hanging fruit, the smallest changes that can have the biggest impact on health. We start there, because long term success comes from the minimum effective dose.⁠

It isn't easy, and anyone who tells you it will be is just trying to take your money. There is no magic pill. There is no shortcut. ⁠

But at Principia, there is support, accountability, encouragement, and fun.⁠

It's easy to blame the aches and pains you're feeling on age.⁠

"Oh, it's just one of the perks of turning 40."⁠

But the truth is, it's not your age that's making you feel like crap.⁠

It's the habits you've been keeping for years finally giving you symptoms you can no longer ignore.⁠

Yes, age is going to slowly make things more challenging. Chances are, you won't be able to do exactly the same things at 70 as you could at 20.⁠

But far too many people use age as a crutch to avoid real change.⁠

Change your habits, change your pain. Young or old it doesn't matter.⁠

Don't believe us? Let us show you!⁠

If you’re living with pain in your everyday life, you know just how frustrating that can be!

And even worse, it can leave you spiraling:
What if I lose all of the progress I’ve made so far?
What if the pain doesn’t go away?
What if things continue to get worse?

We help people get out of pain without giving up their fitness or the activities they love. Want to see if we can help you, too?

Are you working as hard as you possibly can towards your goals?⁠

... We sure hope not. Don't get us wrong, we want you to reach your goals. And that's exactly why we hope you aren't working as hard as you possibly can.⁠

You see, max effort isn't sustainable. Yes, these short sprints will help you see progress quickly. But sprints aren't sustainable.⁠

Sometimes the BEST thing for helping you reach your goals is to slow down.⁠

It sounds counterintuitive, but it's the truth.⁠

"But if I don't try to go all out, I'm afraid that I'll begin to slow down too much."⁠

Yea, that's a concern for sure. Which is why it's key to have a pro by your side to keep you pushing just hard enough to make progress while giving yourself enough grace to be sustainable long term.⁠

After all, you want to reach your goal... and then maintain it, right?⁠

Want to make sustainable, safe, long-term progress? So do we! Let's get you set up on the road to success!

So many say "no" to exciting opportunities out of fear. ⁠

That fear can come in many shapes and sizes:⁠
-Fear that we won't fit in.⁠
-Fear that we won't be able to keep up.⁠
-Fear that we will look stupid.⁠
-Fear of what others might say.⁠
-Fear that we might fail.⁠
-Fear that we might end up alone.⁠
-Fear that it will hurt.⁠
-Fear that it might be hard.⁠

If you don't want to do it, don't. But if you are saying "no" to opportunities that you WANT to do because you are afraid, then there is a problem.⁠

We help people struggling to take ownership over their lives, who feel tormented watching opportunities pass them by, use their fitness to finally feel empowered, confident, and in control of their future.⁠

Sound like something you need? We're here, waiting to help you! Use the link in our bio to get started.⁠

Not one for patience? Want things right away? We feel ya.⁠

Making big lifestyle changes can be hard, especially when you know it may take a year or more to really master.⁠

If you want to kickstart that progress and put it on the fast track, the best way is through one-on-one training.⁠

One-on-one training is the Cadillac (or maybe TESLA nowadays) of training.⁠

It is the high end service for people who really value their health and want only the best.⁠

And it is a great way to speed up your progress, especially at the beginning of your fitness journey.⁠

One-on-one training allows you to learn how to move the right way, from the beginning. ⁠

It is tailor made for your specific body, goals and lifestyle, ensuring that every ounce of effort is going toward what you care most about.⁠

And it has accountability built in to make sure that you keep making progress, even when you don't FEEL like it.⁠

If you want to start fast and furious toward your goals (and make progress in a sustainable way long term), then one-on-one training just might be your best option.⁠

Let's find out for sure! Schedule your free consult with a coach to see if we are the best fit for you and your goals.⁠

Then March is your month! This month only, we're offering 6 weeks of nutrition coaching for FREE for all new members who sign up with us!⁠

Most people who join a gym are looking to lose some fat. But the real changes to body fat don't come from the gym, they come from the kitchen.⁠

The amount of nutrition advice out there is insane! And with so much conflicting advice, it's no wonder so many people struggle to make substantial nutrition changes.⁠

In our 6 week nutrition kickstart, you'll get the education and accountability to start making REAL changes to your daily nutrition that will lead you to the results you're after.⁠

And you'll get it for FREE, this month only! Drop a comment or send us a message to get started!⁠

Have fun! Make friends! Get in the best shape of your life!

Whether you want to compete as an elite athlete, finish your first marathon, keep up with your children, or simply lose some extra weight, our classes will prepare you whatever life throws at you. All of the movements in our classes can be scaled to any ability level, meaning anyone can do CrossFit! Just show up, and we will take care of the rest. The constantly varied functional movements performed at high intensity will transform you into the athlete your body wants you to be. With each movement, our coaches work to educate our athletes about the why behind what we do, before we do it, giving you the tools to make educated decisions about your health.
