Take a look at the pictures above...

Those are some of the AMAZING men and women who joined our transformation challenges this year. While they lost inches and shed pounds of unwanted fat, they gained energy and self-confidence.... and they ended their challenge feeling great about themselves! (Each person is holding the tape showing how many inches they lost during the challenge! So inspiring!)

They made a decision that they were ready for a change and committed to it.

It wasn't "magic" that they crushed their goals... it was simply because they followed a step-by-step plan, had accountability, and were a part of an amazing community who supported them.

Now...It's YOUR TURN.

If you've read this far... it's because you're someone who doesn't want to settle for AVERAGE.

While the "average" person is gaining weight over the holidays... that won't be YOU this year.

You deserve to look forward to your holiday parties... not dread them!

I'm going to show you EXACTLY how to boost your metabolism to burn body fat, increase energy, and cut out stress...WITHOUT giving up any of the foods you LOVE over the Holiday Season!

"My personal goal was to lose the gut with an added bonus of seeing abs…I'm happy to say the gut has significantly decreased and i'm on my way to a 4 pack. I've lost 13.6 pounds and may need to buy new pants cause I've dropped two sizes - a nice problem to have”.

I'd highly recommend this program to anyone serious about changing their habits. You will see results and feel better in the end - even if you don't stay as strict afterwards. Two thumbs up, 10 out of 10, whatever rating system you wanna use - Marissa and team at 17th Street Athletic Club are aces in my book!"
