We understand finding a gym or trainer can be difficult. How do you know a gym or trainer is actually as good as they say? How do you know that your experience won't be a waste of your time or your money?

4 Things to Help you Decide:

1. Listen to others who have already tried the trainer/gym. Feel free to read or listen to some of our hundreds of testimonials of clients and members who have achieved fitness success with Flash Fitness! We maintain a 5 Star Rating on Google Review, which you are free to go read. (We would have a 5 star here, too, but apparently one person who never came to Flash or met us left us a bad rating 3 times! Working for the competition apparently)

2. Look at the number of long-term members and clients we serve. The average Flash client and member stays for years! We have more than 50 people who trained with us for longer than 5 years! TRUST & RESULTS!

3. Flash Fitness GUARANTEES you will see results. Most gyms and trainers will not guarantee your money back because they simply struggle getting results with clients on a regular basis.

4. Know that Flash Fitness does NOT advertise. The gym has grown because members and clients come to LOVE Flash so much that they tell all of their friends, family & colleagues. This only happens when you deliver a great service!

GOOD NEWS, Flash-a-Maniacs!

Hi guys! 👋

I want to share something that means a lot to Ritah and I.
As you know, we are VERY passionate in what be believe about nutrition.

For more than 25 years, I’ve told people to limit carbs, especially processed carbs and sugar, increase the protein and fat.

It’s always felt like we were fighting against the world..fitness certification companies, marketing, doctors, government regulations, etc. Why would people believe US?

Our methods were anti-mainstream and some people even thought it to be a “crash diet” or dangerous.

But….I only care about physiology…not RULES made by politics.

And I cannot unsee what I have seen work for so many people over the last 25 years.

Well….Yesterday, America has flipped their food pyramid to make their nutrition recommendation look ….

Exactly like the Flash Principles we teach YOU!!

After 50 years, of being told to "eat whole grains" and "limit fat."
The new US 2030 Guidelines has officially changed EVERYTHING. 🎉

Here is what they changed…
1️⃣ Protein is now King: They now recommend up to 0.7g of protein per pound of body weight.
2️⃣ The "Inverted" Pyramid: The new chart puts Meat and Vegetables at the widest part at the top. Grains are now at the bottom.
3️⃣ War on Processed Food: On their website, they are warning against seed oils & processed sugars.

I cannot describe the relief I feel….after fighting against the grain all of these years …to finally have our methods “validated” by ahem… “authority” or “mainstream.”

I’m honestly a bit emotional. Sorry. Hehe.

It’s a big moment for us because it confirms what we’ve always taught.
Our methods were never a fad. It was never “extreme.” They were never “dangerous.”

It’s physiology….and it doesn’t care about anyone’s politics, economy or ideology.

So, while the rest of the world changes their diet, you just need to keep doing what we do every week.

🙏 THANK YOU all for your TRUST all of these years…
for believing in us when we went against the grain.
You are appreciated.

See you soon,
Jeff and Ritah

Hi again! 🙂
For 13 years we’ve built Flash Fitness and maintained a 5-star reputation. This past several days, we’ve been hit with more than 50 fake reviews from accounts that have never contacted or met with us.

We’ve reported them, but Google …well, has done nothing…
and it matters because these reviews affect how people find our small business.

If Flash, Jeff, or Ritah have ever made a difference in your health or fitness journey, as a private client, Flash member, online client, consultation, yoga client…..
Please take 30 seconds to leave a Google review and help us battle back.
It’s YOUR voice that helps keeps us visible and strong.

Thank you sooooo much, gang! We appreciate you 🙏

Can you help us, Flash-a-maniacs?
Does anyone know what to do?
Flash has been targeted and getting bombed with a bunch of fake reviews from people who have never contacted us or set foot in our gym….using fake accounts to lower our 5-star rating, which we’ve had for over 13 years…and has now been successfully undone.

Every day, we’re getting 3 or 4 star ratings from someone (a bot maybe?) who has never contacted us or ever stepped foot in Flash.

We’ve been reporting it to Google…but we hear nothing back.

Does anyone know how to go about this?

To small businesses like ours, it’s very important because the rating plays a large part in Google search and hurts the reputation that Ritah and I have worked so hard to build over 13 years at Flash.

You guys know we put our heart ❤️ and soul into Flash and it is so frustrating to see how quickly that reputation can be hurt by this stuff.

Thanks for any input…
Jeff and Ritah

CONGRATS, Dr. PAT! Pat Pailin Lee Conquering Goals & Getting her 1st Chin-Up!

Look at that photo! That is the exhilaration of achieving your first unassisted chin-up! It was goal of hers and she said “I didn’t think I could ever do a chin-up.”

Well, we told you that you could! A massive congratulations Pat, for this monumental feat!

This is a major accomplishment, as less than 5% of women can perform even one unassisted chin-up.

At Flash, we believe in training smarter. You won't see us using resistance bands for chin-up practice, and here's why: Bands offer the most assistance where you're weakest (at the bottom) and the least where you're strongest (at the top). This opposite of what we want. The counterproductive resistance profile interferes with building the crucial strength you need where you need it most.

If you want to get better at chin-ups…ditch the resistance bands!

Want to achieve your first chin up?

Let’s start your incredible own set of incredible accomplishments.

Congratulations Jean and Oh for completed first Hyrox Thailand , you guys did so well and we are so proud of you 💪🎉
