Are you sitting down right now? You might want to stand up for this – or hopefully want to stand up by the end of this article. Do you dread working, attending meetings, or even checking emails, knowing that you will be confined to a desk (or desk-like setting) for hours on end? Do you feel more tired after sitting for a long time, antsy, and even a little achy?

After years of back pain, feeling antsy, and simply uncomfortable at my desk, I became intrigued with the idea of having a standing desk. This is not to be confused with a treadmill desk (which, in my opinion, looks like a deadly accident waiting to happen); and I already knew a few people who owned standing desks and highly recommended them. However, I put off the idea, thinking I would just suffer and sit through any discomfort at my “regular” desk.

In November 2013, I received a big wakeup call that I needed to get a standing desk – and fast. After a fluke...

The world of fitness is changing! Sportswear, gear, gadgets, food and fit services are more forward-thinking and edgy than ever. I've been testing a few that I'm crushing on which I'll share with you, as well as give you a sneak peek at some extremely functional pieces coming out from Asics. The theme that binds all these trends is Ease of Use. I was surprised as I'm typically a skeptic about adding too many elements to my routine. I don't have time for inventions that steal valuable calorie burning minutes away from my workout. But I'm seriously impressed by how the following trends can raise your engagement without sidetracking you.

   Let's start with BURN THIS.

This is a free app that turns your workout into a social experience. It's available to people living in major cities like NYC, LA, CHI, MIA, and more. Download it to your iPhone, then look up all those studio classes you usually book on Mindbody from the studios you...

Fred Devito is one of the founders of Core Fusion as well as a founding partner of the exquisite Exhale Spa locations around the world. He is widely known and incredibly respected in the fitness industry. I've learned a great deal from him, which you're going to hear all about.

What I've learned from Fred can be broken down in 3 stages of knowing him. There's the "DVD" Fred stage (consisting of many living room workouts...and intermissions to catch my breath), the "O.M.G. I just took class from the real-life Fred Devito" stage (and I wish he would look away so I can stop holding this awful pretzel pose), and lastly the "One To Admire" Fred stage. I should mention that Fred turned 57 on the day that I interviewed him for this article. He told me he'd been in the fitness game now for 30 years. I asked him if he planned to take a break and he said:

"I'll never stop doing this." - Fred Devito

I got into barre-fitness workouts in 2007...

Alo! It's been a crazy week of press previews and testing new fitness products. My body is totally TGIF-ing from both work and daily killer workouts. But every Friday has to end with something good and I've got exciting news about upcoming trendzz I want to share with you.

By now you must know I have a BOX with Quarterly Co. If not, WHERE HAVE YOU BEEN? My Style Up 2 Shape Up Box is one of my most favorite projects and collaborations EVER! The best part is being able to share fit trends with you and get your feedback. Check out my latest "unboxing" video for #MIZ02 above. You've got plenty of time to sign up for the next box which comes out in May and features lots of restorative and beauty goodies for your hard-worked body.

Subscription boxes can be a hard sell for people who don't like surprises--I get it. But THESE VIDEOS will give you a reassuring peek into past boxes. Got questions about my SU2SU Box? The comments section is the place to ask them.

So,...

Melissa Jane King let me follow her around Thompkins Square in her Lower East Side (LES) 'hood of New York City for the very first of my "Followed" posts. Isn't that what we do...follow the style cues of women brave enough to create and flaunt them?

I'm inspired by people who make my job of Fitness Trend Reporting less predictable, especially those who practice fitness fashion on local streets and rural paths in ways not always defined by conventional fitness. You'll be seeing more of that here on Mizzfit.com because I want you to see people creating trends at their inception, not just wearing them after-the-fact.

Thanks to Melissa Jane King and baby Olive for being my first!

"I’m not sure I am fit…I’m naturally thin so perhaps this gives me the appearance of being fit. After Olive was born I began ‘Belly-Back’ exercises. They’re awesome because you can do them anywhere – it got my stomach and waist back in shape after a few weeks. In terms of...

As you already know, fitness fashion can easily take you from studio to street...and these days fitness fashion totally chases what’s on the runways making it easier to seamlessly rock your workout look multiple ways. Last year we saw a lot of peplum. The designers for AEO Performance from American Eagle Outfitters took this ladylike style and used moisture-wicking material to make it perfect for workout and hangout. Pictured below is the AEO Performance Peplum T-Shirt:

This spring, fitness fashion is echoing some of the hottest trends and translating them into workout looks that will inspire you to make the gym your catwalk.

Here are 5 Springtime Fitness Fashion Trends for all you fearless groundhogs out there!

1. CROP TOPS

CT's are making a major comeback this spring and summer. They started cropping up last summer but now you are going to see this midriff showing style everywhere...even at the gym. Under Armour is really doing an awesome job making this...
