Jackie's back and sporting a new do and crew

Season 3 premiered Jackie's new hairdo, longer (but not long) locks that add a little femininity to the alpha male persona she represents so well. Not only that, she's also sporting a new crew. Not entirely of course, but new trainers and a new girlfriend. So, who's new and who didn't come back from the previous seasons? Keep reading.

Down and out
First things first, let's get this one over with. Zen Gray fans might not like this, but she's not back. For reasons that escape me, our wonderful little Zen didn't return to what appears to be the most dramatic Work Out season to date. Maybe that's why. Our man Andre Riley is also not back for the third season.

Who's in?
Work Out fans were treated to some new faces Tuesday night, and they didn't disappoint. Not only are they beautiful but fiery as well. Here's a brief look at the new crew:

Agnostina Laneri
Born and raised in Buenos Aires, Agostina is a 26-year-old Argentinean who is not afraid to speak her mind. Her love and interest in fitness began at the age of 15 when she started training in martial arts. At the age of 19 she decided to pursue her love for the fitness industry in Hawaii. After obtaining an extensive education and certifications she began working at five star hotels in Maui. Her clientele now ranges from professionals to celebrities.

Since winning Bravo's Hollywood & Highland competition to join Jackie's gym as a trainer, she has enjoyed a flourishing career at Sky Sport & Spa, and has even enjoyed some flirtatious fun with her new boss, Jackie.

Agostina's Fitness Philosophy: Don't stop 'til you drop.

Greg Plitt
The former Army Ranger, All-American Wrestler, and Master Fitness Trainer grew up in Baltimore Maryland. Aside from his rock-hard abs and successful fitness career, Greg has been involved in a number of different activities throughout his life. This jack of all trades is certified in scuba, airborne, air assault, combat lifesaver and hand-to-hand combat. He's a sponsored athlete with MET-Rx Nutrition and is currently the spokesperson for the Under Armour performance apparel.

Greg's career in the fitness profession began when he was approached in Washington, D.C. to do a cover for Muscle and Fitness Magazine where he was inspired to continue on the road of fitness and training.

Greg's abs of steel have adorned more than 50 fitness magazine covers and he considers himself somewhat of a celebrity in the field. His body will have the male trainers envious and the female trainers salivating. His mere presence will heat up the gym as he is determined to stir things up at Sky Sport & Spa.

Greg's fitness philosophy: Fitness is not about the vanity of what you see in the mirror, but the transformation of how you feel on the inside. It is a lifestyle and process that excels oneself in all theaters of life through a mind and body connection. When you are physically fit and feel in shape, everything else in life is easier.

JD Jordan
JD is a tall, dark and handsome Los Angeles native. He's been a masseur to many of Hollywood's leading artists and now wants to take his newfound passion for personal training to the next level. He's looking to Jackie to take him under her wing and show him what it takes to be a top trainer in a very competitive world. He is currently working on his Pilates certification.

In JD's personal life, he's looking for an intelligent, masculine guy that will rock his world and says he's sick of choosing men that need to be saved. JD wears his heart on his sleeve, and too often that's what gets him in trouble.

Renessa Williams
This bubbly South Dakotan is all smiles. As a single mom of an 11-year-old, she is looking for the right guy. She's trained alongside Brian Peeler for years and considers him a brother and confidant. Unfortunately, she has no idea that her ties with him may put her in jeopardy with her new boss, Jackie.

Renessa is fitting in well at Sky Sport & Spa. Her fearlessness and drive have paid off with her clients, who find her to be a humorous and positive role model in the fitness world. Her outdoorsy attitude would rival most adventurers, and she has a knack for learning new things, whether it's the guitar or dancing.

Renessa has also worked with renowned health and wellness expert, Mike Torchia, who has trained celebrities like Matt Damon, Al Pacino and Kevin Spacey, among others.

Renessa's Fitness Philosophy: Exercise! Mental and physical health is of the greatest importance. Get obsessed with being healthy and become an addict for life.
