What makes our program different

In the world of athletics, men are always the dominant sex in the weight room, often starting at a young age.

Most females never enter a weight room until their freshman year of college…

Yet they are exposed to the SAME demands as male athletes on the sports field….

At Relentless, we wanted to change this.

We KNOW female athletes are just as athletically capable as their male counterparts and deserve to be trained similarly.  

For this reason, the Relentless Program provides individualized coaching programs to our female athletes within a small private 6:1 athlete-to-coach ratio.

We maintain a female-only training environment as this allows us to create a community of STRONG, like-minded female athletes who, although competitive, are equally supportive of one another.

Our Team

  • Emily Neff (Pappas), PhD(c)

    Emily is the Owner and Program Director at Relentless.

    In 2015, Emily opened Relentless Athletics to build a community for female athletes while educating their parents and coaches on the necessity of strength training and sports nutrition to optimize sports performance and reduce injury risks in the female athlete population.

    Emily is a Ph.D. candidate at Concordia University St. Paul with a research focus on female athletes & the relationship between strength training, ACL injury rates, and menstrual cycle irregularities (RED-s). She holds an M.S. in Exercise Physiology from Temple University and a B.S. in Biological Sciences from Drexel University.

    Through this education, Emily values her ability to coach athletes and develop strength coaches, using a perspective grounded in biochemistry and human physiology.

    In 2020, Emily was an Adjunct at Temple University, instructing a course on the current research behind female athlete development. Additionally, Emily has worked as a consultant in developing health education curriculums at the high school level.

    Emily has over a decade of experience coaching female athletes, working with athletes ranging from adolescents to the collegiate and nationally ranked levels.

    When she isn’t on the coaching floor or working in her office, she is at home with her husband Jarrod, their daughter Maya, and, of course, their dog Milo (who has become the mascot of Relentless)!!

  • Brielle Adolph, M.Ed.

    Coach Brielle is the Director of Training at Relentless!

    She holds her M.Ed. in Sports Administration, her CSCS, and USAW-L1.

    I am from Cypress, Texas, and growing up I always had a love for sports and fitness. I was a college-athlete at Southwestern University, where I had the privilege to swim and obtain a Bachelor's in Kinesiology with a minor in Business. I also pursued my first strength and conditioning internship at Southwestern University, where I worked with about 13 varsity sports teams and learned the biomechanical importance of strength training for sports.

    After graduation, I completed a summer-long sports performance internship with the Strength and Conditioning staff at Rutgers University. I then went on to pursue a graduate assistantship at Midwestern State University in Wichita Falls, TX, where I earned a Masters of Education in Sports Administration. I was in charge of Volleyball and cheerleading and assisted the Head Coach with Football and Men’s basketball.

    I landed my first full-time position as an assistant strength and conditioning coach at Yale University, where I was in charge of Softball, Gymnastics, Swimming, Diving, and Fencing. My journey in college athletics continued with a short stint as an assistant swim coach at Amherst College, where I had the opportunity to embrace new coaching challenges and refine my coaching skills.

    On a more personal note, when I'm not in the gym, you can find me binge watching Law and Order, trying new foods, or sitting at a coffee shop.

    I am thrilled to be back in the world of Strength and Conditioning and am even more excited to be at Relentless Athletics. I plan to leverage my passion for strength and conditioning at Relentless Athletics to mentor and support young women so they feel confident and strong!

    I am from Clarks Summit, Pennsylvania and grew up loving soccer. I started playing at the age of 5 and was lucky enough to continue on through college at the University of Scranton.

    I pursued my passion for fitness off the field, as well, by earning my Bachelors degree in Exercise Science. After
    graduating, I moved to New York to pursue a Masters degree in Applied Physiology at Teachers College Columbia University.

    I spent the first few years after graduate school working at Mount Sinai Hospital in New York and later landed at Penn Medicine in Philadelphia as a Registered Clinical Exercise a Physiologist.


    I decided to transition to working full-time in fitness and gained my Certified Strength and Conditioning Specialist certifications.


    I started out as a group fitness coach and Sales Manager at F45. I took my career one step further by eventually becoming the General Manager at CycleBar. I learned a lot about leadership, team
    management, and supporting a membership community.


    On a personal note, when I’m not at Relentless, I’m either working out on my own, spending time with friends, reading, or painting.

    Fun fact, I just ran my first Marathon this November in Philadelphia!


    I’m so excited to be a part of this community and can’t wait to see you all hitting your PRs and growing as athletes!

    Education: I did my Bachelor's of Science in Exercise and Sport Science at Temple University in Philadelphia and did my Master's of Science in Human and Applied Physiology at King's College London in England.

    Hometown: Lansdowne, Pennsylvania

    Sport: I played basketball from the age of 5 until the end of my high school career. I loved watching Kobe Bryant and Maya Moore, and they motivated me to be a better athlete and person.

    School/relevant experience: I attended West Chester University, where I received my B.S. in Exercise Science and a Minor in Nutrition.

    After working with D1 Training: Malvern and Whirlwinds Speed Academy I had the opportunity to train and coach young athletes from the ages of 9 until 18 years old of age, which re-ignited my passion for being around athletes/sports and knew then that I wanted to fully commit to Strength & Conditioning.

    I recently had the opportunity in 2024 to intern at the University of Delaware, where I assisted in training the Women’s & Men’s Basketball teams, Women’s Lacrosse, Women’s Track & Field Team, Women’s Rowing, and Men’s Baseball. During my time there, I was able to gain hands-on experience with Division 1 athletes and learn how the Strength Coaches program improves their performance and aid in their recovery as well. In my spare time I also Coach for U2 Athletics AAU Girls Basketball team, which I love because it allows me to be around the game of basketball and mentor young ladies to become better basketball players.

    Fun fact: Outside of the gym, you can find me enjoying yoga classes, hanging out with my friends, eating tacos and nachos, outdoor running, and traveling to the beach!

    Why Relentless: I’m excited to be at Relentless and to be fully in the Strength & Conditioning world and create a space for young female athletes to enjoy sports and encourage them to be the best player they can be for their sports!

  • Christina Marchitelli, M.S.

    Coach Christina is an Assistant Coach at Relentless!

    She holds her MS in Sport Management, her BS IN strength and Conditioning for Human Performance with a focus in Health, her USAW-L1, and is currently completing her CSCS.

    I am from Staten Island, New York. I fell in love with running at the age of 6 and during elementary school was even a New York Road Runner Youth Ambassador which meant speaking publicly about the health benefits of running.  I really enjoyed running from elementary school through college because it provided the thrill of competition along with the sense of community that came from being part of the track and field and cross-country teams.

    I decided that I wanted a career working with athletes to improve their performance and prevent injury and attended SUNY Cortland where I obtained my Bachelor’s Degree in Strength and Conditioning for Human Performance with a focus in Health.

    While at Cortland, I completed 4 strength and conditioning internships working in private, high school and Division 3 college level programs. I worked with the following sports teams: Football, Flag Football, Basketball, Softball, Baseball and Gymnastics.

    After graduation, I had the opportunity to participate in a summer strength and conditioning internship at Wagner College’s football training camp as part of their Division 1 program.

    Wanting to learn about the business side of the sports, I returned to SUNY Cortland to obtain my Master’s Degree in Sport Management. While completing my Master’s degree, I  also worked as an Assistant Strength and Conditioning Coach at SUNY Cortland. I was in charge of Women’s Soccer, Women’s Hockey, Men and Women’s Swimming and Diving and assisted with Football. During my time as an Assistant Coach both Women’s Soccer and Women’s Hockey won the SUNYAC Championships, and the Football team won the Division 3 National Championship! These were all amazing achievements to be a part of and see everyone’s hard work translate into victories.

    I worked for the NY Jets as a game day and events staff member for the 2024- 2025 season. Working with the fans to make the games and community events memorable was rewarding.

    I am so excited to be a part of Relentless and make working out something that every young female values and enjoys! My goal is to encourage every young woman to become confident both in and out of the weight room. I cannot wait to see all the PR’s that will be happening!

    She holds her MS in Sports Management, her BA in Exercise Science with a concentration in Strength and Conditioning, her CSCS, and is pursuing her USAW-L1.

    I am from Lincoln, Kansas and attended Lincoln High School. I have always had a love of sports and grew up watching Kansas University men's basketball games. I was lucky enough to play volleyball, basketball, and softball in high school and went on to play volleyball at Ottawa University.

    While at Ottawa, I was able to intern in the weightroom and spend many hours with a variety of athletes and see how to coach their programs. I also interned for Kansas University Football with their strength and conditioning program.

    After graduating from Ottawa, I went on to become an assistant strength and conditioning coach at Ottawa for the spring semester. Starting in the fall, I was a graduate assistant coach for Tusculum University with their strength and conditioning program. While taking classes for my masters degree, I coached scout team football, women's lacrosse, women's basketball, and cross country. All of these experiences led me to become a strength and conditioning coach at Relentless and continue helping athletes reach their full potential!

    Fun fact: I love any outdoor activity like hiking and kayaking and am always on the lookout for a new trail or local coffee shop!

    Why Relentless: Relentless has a great culture for its staff and athletes, while creating a space to continue to learn and grow. Getting female athletes ready for competition and creating a healthy environment for them to do so is something I strive for and believe Relentless is the best place to continue to do so!
