From Our Founder: Shay Kostabi

A former dancer and performer, Shay Kostabi brings her energy, charisma, and grace to every endeavor she undertakes. She is one of New York City’s most popular fitness personalities as a master trainer at ReXist360, and with affiliations to Qinetic, New Balance, Essentia Water, Designer Whey, and many other brands.


Shay’s creativity in fitness choreography is what sets her apart in the industry. She combines dynamic, complementary exercises to create movement patterns that feel natural and are fun to follow. Because muscle tension builds throughout multiple repetitions and progressions, you’ll still get that burn, but you won’t be bored with high rep counts.

In Total Body Toning, Shay hits five body parts with progressive exercises that work from basic to more advanced modifications. Just when you’re ready to give up, Shay moves you to the next progression.

Shay’s Burlesque & Strength plays on the trend of boudoir workouts, giving you both a sleek, sculpted body and some moves you can try as foreplay.

In addition to these workouts, Shay leads the ReXist360 workout series. The series consists of six different workouts that range from high-impact, plyometric-based to targeted toning and sculpting. Including a workout designed specifically for expecting moms. All of these workouts utilize the patented ReXist360 bands, which you can learn more about here.

Turkish Bathhouse

If you’ve never visited a Turkish Bathhouse before, you’re missing out. A Turkish bath combines steam with hydrotherapy to offer great benefits for your body.  The heat helps to improve circulation, which helps with muscles aches and allows your body to detoxify.  Along with muscle soothing, a Turkish bath will help clarify your skin and encourage relaxation to reduce overall stress.



If you like to get your body moving a bit more on your rest days, yoga is a good option. In addition to relieving stress and improving focus, yoga has great benefits on your body.  Yoga helps improve strength and increases flexibility, which helps improve your workout performance.  A good yoga routine will take your joints through their full range of motion and encourage good posture, which helps prevent injuries and degenerative diseases like arthritis. Try Zander Gladish’s Fusion Yoga, which includes strengthening yoga poses and cardio to benefit your total body.

The great thing about water is that it helps support your body weight – when standing in waist-high water, your body only has to support half of its weight. The result of this is that less stress is put on your joints, reducing your risk of injury.  But, this doesn’t mean that swimming is an easy workout – as water is 12 times as dense as air, your arms and legs are experiencing resistance as you proper yourself through the water, which helps boost strength.



It’s probably no surprise that stretching helps improve flexibility and reduces the risk of injury, but did you know if can also improve your performance?  A review of 23 studies published in the Clinical Journal of Sports Medicine in 2004 found that regular stretching improves athletic performance by helping to improve muscle force and velocity.  However, stretching was actually found to worsen performance when done right before an event, so sticking to stretching post-workout and on rest days is ideal.  Try Shay’s Recovery Flow, a quick routine that will help you take care of your body on your day off.





6 Healthy Snacks to Take On The Go


When you’re busy, it can be difficult to eat right.  With a little planning, you can have access to nutritious snacks to help keep your energy up and nourish your body (and prevent you from grabbing something unhealthy!).  Trainer Shay Kostabi shares her favorite snacks to take on the go to give you some tasty options

1. TJ’s Egg White Salad

Whether you’ve forgotten to pack a snack or want something easy, Trader Joe’s Egg White Salad makes a tasty and healthy snack.  Each container boasts 14 grams of protein to help keep you feeling satisfied, with only 100 calories.  Creamy yet guilt-free, try the classic chive flavor or the spicy ranchero flavor if you like a little kick.

2. Almonds

Keep a baggie full of almonds in your bag, and you’ll have an easy snack full of protein, healthy fats, vitamins and minerals. Almonds also contain fiber, which has been shown to help you feel full longer, playing a role in maintaining a healthy weight. One ounce of almonds contains 40% of the recommended daily allowance of vitamin E, a powerful antioxidant, to help keep you healthy.

3. Designer Whey Protein Bars and Protein Shakes

Whey is a complete, lean protein that helps build muscle, increase strength and reduce hunger.  Shay loves Designer Whey Bars and Shakes because – unlike other whey products – they don’t require refrigeration.  The 100-calorie shakes contain 18 grams of protein and would make an excellent post-workout drink, while the bars contain 10 grams of protein and 170 calories or less to keep your energy up throughout your day.

6. Cucumbers
