About Me
Meet the founder
Hi! I’m Justine McCormack, founder and head coach of Next Legacy Tumbling & Stunting LLC.
My love for cheerleading began in 2000 with Pop Warner and grew into competitive cheer at Extreme All Starz, where I competed throughout middle and high school while traveling nationwide. During that time, I also began coaching — and I’ve been coaching ever since.
​
After graduating, I continued cheering at Extreme and later CC Champs. While I took a break from competing, I stayed deeply involved in the sport through coaching and have proudly served as Head Varsity Cheer Coach at Clarkstown South High School since 2016.
In 2023, I returned to the mat as an athlete on multiple international cheer teams.
​
Outside of coaching, I work full-time with FDNY EMS, a career that has shaped my leadership, discipline, and ability to stay calm, focused, and supportive under pressure — qualities I bring into every practice and lesson.
Cheerleading has taught me far more than skills. It’s built my confidence, work ethic, and belief in what’s possible through consistency and positive coaching. I created Next Legacy to give athletes a space to grow strong foundations, confidence, and self-belief in a supportive environment where every athlete feels seen.
Whether it’s a first cartwheel or advanced skills, every athlete has a legacy to leave — and I’m here to help them Leave Your Mark.
Our Programs
Tumbling
Mastering the Art of Tumbling
At Next Legacy our tumbling program is built for athletes who are ready to grow their skills with confidence and proper technique. Whether your athlete is just learning a cartwheel or preparing for advanced passes, we offer structured levels that meet them where they are and help them level up-safely and confidently.
Each class is taught in a postive, small-group environment where athletes receive individualized attention, skill breakdown, and strength-focused drills. We emphasize clean progressions, body awareness, and long-term development over shortcuts.
Stunting
Elevating Stunting Skills
Our stunting program at Next Legacy is built for athletes who want to develop strength, timing and teamwork through safe, structured training. Whether you're brand new to stunting or looking to clean up advanced skills, this program builds confident bases, strong flyers and trusted spotters.
Each class emphasizes proper technique, body control, and partner/group communication to help athletes perform stunts with precision and safety. Athletes will learn how to lift, support and fly-with drills focused on form, stability, and progression.
