Leah Callovini

Leah recently relocated to Philadelphia from Washington, DC, where she began her fitness career five years ago. Leah participated in team sports in high school, but never really found her home in fitness until college. She fell in love with group fitness while studying at George Washington University. She began teaching Cycling classes in 2012 for the university's Campus Recreation program, which helped her realize her passion for helping others live their healthiest lives by developing healthy habits. After graduating from GWU with her BA in Psychology in 2014, Leah missed studying so much that she then self-studied and obtained both her ACE Group Fitness and ACE Personal Training Certifications within one month of each other. Her group fitness manager convinced her to sign up for the LesMills BODYPUMP Instructor Training program in 2015, which changed her life forever. Leah loves the energy and physical challenge that comes with BODYPUMP's continuous tension training and can't wait for her NGU participants to feel the burn!

Leah worked full-time as a corporate fitness professional for a large government agency in the DC-area before relocating to Philadelphia in January 2017 to pursue her Master's in Sport Business at Temple University. Leah can't wait to get to know her participants at NGU Training: She finds herself continually challenged by her participants and hopes to inspire them to do what they think they can't.

Ann Rejrat

Ann comes to us from Scranton, Pa. She moved to Philadelphia to pursue a degree in Journalism at Temple University in 2008 and fell in love with the area. Ann has a lifelong passion for fitness starting from when she was a child trying to keep up physically with her 5 older siblings. She played numerous sports through high school and college including swimming, softball, cross-country running, and track and field. In college she also worked at the University’s Campus Recreation Department where she continued to grow her love of fitness. As she has gotten older her approach towards fitness has developed to focus on not only the physical results but also the mental. To her, workouts should be just as fun and engaging as they are physical. People should leave their workouts feeling a sense of accomplishment not defeat.

She is a AAAI-ISMA certified Personal Trainer, AAAI-ISMA certified Cycling Instructor, and AAAI-ISMA certified Yoga Teacher.

Ann is excited to bring her lifelong love of fitness and health to the members of Never Give Up Training. She hopes to grow with her students as they travel on their fitness path towards their goals.

Morgan Dowd

Morgan is a NGU Group Fitness Instructor, NASM Certified Personal Trainer and graduate of Saint Joseph's University. Growing up she was constantly active as a gymnast & competitive cheerleader, until an ankle injury ended her college cheerleading career at Rutgers University. It was at that point that she became extremely conscious of her body & weight which ultimately spiraled into a nearly fatal eating disorder. After 4 years in recovery, she consciously chose to turn her unhealthy obsession with exercise into a healthy outlet to manage stress and anxiety. She believes that getting that second chance at life has only fueled her passion to inspire wellness through exercise. Morgan has a passion for continued education in functional training and nutrition in order to provide the best for all of her clients and classes.

Macalla Curtis

Macalla is not only an NGU Group Fitness Instructor, but also is a NASM Certified Personal Trainer and can whip you into shape! 

She holds the type of character that could be called contagious and exemplary. While Macalla brings with her to class a tremendously bright personality, a passion for fitness, an appreciation for life and a drive to always get better... She is also prepared and trained to perfection. She is always working towards her goals in whatever facet of life they may pertain to.

Macalla emerged as one of the most consistent competitors the Towson University gymnastics team has ever had, which is a testament to her ability to stay calm and focused under pressure.


What is most important, however, is Macalla the person. She is extremely passionate and dedicated. She has a great desire to continually gain knowledge and experience that will not only help to improve her own mentoring skills, but will also help those individuals she works with. Macalla is the type of person that pushes her and others to become better than they were yesterday, a belief that is embodied in the essence of the N.G.U. core. She will help push you to become the best person you not only want to be, but also will help push you through the battles in life and in training to become the person you may of never thought you could be.
