Karina Melo, Founder & Personal Trainer

Karina Melo is a personal trainer, veterinary nurse and entrepreneur of Colombian origin. Her interest in serving the community began throughout her work as a choreographer for the non-profit organization Circulo de la Hispanidad, where she taught children ages 5 to 16 of the Long Beach School District. During her 14 year career as a veterinary nurse, Karina also participated in community events, fundraisers, multiple beauty pageants and choreographed private events in the Long Island and Queens areas.


In 2014, wishing to begin her personal coaching career, Karina became a Zumba instructor, and a certified National Academy of Sports Medicine (NASM) Personal Trainer. Since then, she has dedicated her time to the development of her own gym and brand, K-Fit, keeping her community involvement at the helm of her goals.


In 2017, Karina opened her first K-Fit Boutique Gym, currently serving over 300 women across all fitness levels and ages. In a private, non-intimidating and inclusive environment, Karina provides tailored one on one personal training sessions, and  group classes while helping women reach their personal health goals.  Karina is specialized as a personal trainer in Women's Fitness, adding pre-natal, post-natal and seniors to her compass.  She continues to serve her community as Vice President of the Lions Club of Elmont and looks forward to expanding her business to a much wider group through the development of K-Fit Kids and Leading Latinas en NY- LENY Global.

Rosa Lopez became a certified personal trainer in 2018, when she obtained her NASM, CPT, and ASFA certifications. Her fitness journey however goes back to 2016 when she dedicated to setting personal weight loss goals and a fitness routine. Along her fitness journey, Rose has competed in four NPC Body Building competitions and placed in the Top Five. Her competitions have allowed her to gain great insight into the abilities of her body and the importance of individualized nutrition and training strategies. Her passion for helping others reach their goals keeps her motivated as a trainer during personal and group classes. 


Rosa’s journey doesn’t stop at the gym, she takes her nutrition very seriously and enjoys meal prepping for the week. This love for meal prep continues to grow as she begins pursuing her dream of opening her own meal prep company.


 As part of the K-Fit team, Rose continues working to inspire individuals to live a healthy active lifestyle no matter their circumstances, as she likes to say, “You’ve been through worse than this!”
