About Allie Grantz
Founder. Owner. Instructor.
My journey into health and fitness began more than 20 years ago when I took on my very first training client, ME! At the time, I was overweight and very unhappy. The more unhappy I became the more the scale went up. To say the least, it was a vicious cycle. To end the cycle I decided to join a gym (which was probably the scariest thing I had ever done). I took residence on an exercise bike where I observed everything in my line of vision for the next few weeks. The one thing that really stood out to me is that none of the trainers really paid much attention to their clients. A switch flipped and I decided I was going to start studying to become a trainer. I wanted to become the trainer that I never saw at that gym - attentive, caring, and informed. During this time I also found a love for indoor cycling and taught for over 10 years in the Lehigh Valley. Life has a way of coming full circle and I’m so happy to be back in the saddle!!
​
On the bike: One of the things I love the most about indoor cycling is the music. Music has the ability to turn a not-so-good day into a great day. I love watching people challenge themselves through a tough climb or sprint and realize when they’re done that they did it!
​
Off the bike: My favorite muscle groups to train are legs and biceps. Don’t worry though, we’ll be hitting them all up!!
​
What are we listening to? Anything upbeat and probably a lot of Pitbull.

Fitness is my passion, both personally and professionally. From designing and executing my own workout programs in the gym to being CycleFit's most tenured coach (after Allie, of course), I’m fully committed to it. What motivates me? The reward of sharing this passion, empowering others to push their limits and discover their full strength.
Whether on the bike or mat, I offer challenging workouts in an encouraging environment where all experience levels are welcome. To keep things interesting, I might coach a fully choreographed cycling class or completely wing it to music that inspires me. But one thing is true about every class - it’s a damn good time.
What we're listening to: High-energy EDM, or dark, hard-hitting pop also known as salt or music that might make you question who hurt me. Really, we're listening to anything with a beat. You’ll be surprised what I’ll hit a tapback to.
On the bike: My cycling classes are fast paced and engaging. I change positions a lot to keep us moving and to distract us from the heavy resistance and unnecessarily long pushes built into my choreography. There’s no shortage of sweat.
Off the bike: Sometimes I’ll do the workout with you, sometimes I won’t, it all depends on the amount of coaching the class needs. Either way, every class includes a great workout, good music, and all the energy I have to give.

My fitness journey began many years ago. I started out taking group classes and running and eventually began teaching myself. In 2016 I decided to "retire" from teaching and focus a little more on myself. In 2019, I competed in my first body building competition. Along the way I have also ran many 5ks, 10ks and half marathons. I currently and working toward becoming an ultra runner. The best part of sharing my love for fitness is watching others "catch the bug" and change their lives for the better!
On the bike: I will push you, but we will have a blast doing it! When you come into my class, you never know what I might throw at you but I can assure you, you'll leave feeling great!
Off the bike: I can usually be found in the woods! I love trail running and finding new places to go. When I'm not running, I'm on my ATV or snowmobile in Tug Hill NY.
What are we listening to: I love all kinds of music and finding fun ways to set my class to it. We'll be riding to anything from rock, 90s hip hop, today's hits and country. I love a good theme as well!


ALYSSA KRESGE
My passion for fitness and becoming a fitness instructor was inspired by my Mom. She has been a fitness instructor for my whole life, and it’s always been something I have enjoyed being around. I became a cycling instructor in May 2021 while living in Philadelphia during my doctoral studies at Temple University. As a physical therapist, I additionally have a passion for overall health and exercise. I am a very physically active person via strength training, HIIT training, running, walking, biking, hiking, and whatever gets me outside! Using my knowledge from my education and career, I look to create a welcoming and safe environment for all riders. I have had the opportunity to teach at a variety of studios since receiving my certification, both in Philadelphia and the Lehigh Valley.

I believe that, growing up as an avid dancer and runner, I have the perfect background for being a fitness instructor. I thrive on the adrenaline rush of the cardio workout and love creating playlists to jam out to during my class. You can expect high energy music and a dynamic cycling working with rhythm moves, hills, sprints, and power intervals. I like to ride to the beat of the music, while also emphasizing power and strength! I am really excited to be joining the CycleFit team and I look forward to meeting all of you on the bike!
COURTNEY HAMMERSTONE
I've always been an active person. My passion for fitness developed at a young age through participation in youth sports. I continued to play basketball and field hockey, ultimately finishing my field hockey career at the collegiate level. When no longer a competitive athlete, I struggled to find purpose in training. I soon realized, however, that exercise is not a tool for us to reach our goals, but instead a pivotal part of maintaining a healthy lifestyle. I believe that fitness is not just about physical health, but also about mental health and well-being. It's important to take time to prioritize our health, and I hope that my class can act as an escape from the stressors of daily life and allow you to focus on yourself for a while.
Over the years, I have still found ways to feed my competitive spirit - most notably participating in a few half marathons. However, my decision to join the CycleFit team was not driven by competition, but rather community. I attended a few classes and felt an overwhelming sense of motivation from those around me. It allowed me to feel the sense of comradery and fulfillment that I had been lacking. One of my favorites parts of exercising in a group setting is seeing people accomplish things they never thought possible. Whether it's pushing through a tough climb or setting a new personal record, I love seeing people surprise themselves and feel pride in their accomplishments. Together, we can push through the tough moments and celebrate the small victories. My goal is to create a positive, energizing and supportive environment where everyone feels welcomed and valued, regardless of fitness level or experience. Let's work hard, laugh, and sweat together!


SARAH PEZZINO
Introduced to fitness at a young age, I have always thrived in the fitness community. From spartan races, triathlons, MMA, soccer, basketball, CrossFit, running, cycling, I feel like I have done it all. Now a full time student at Lafayette College majoring in Biology with a concentration in Nutrition & Fitness to turn my love of health and fitness into a career. Fitness is more than a passion for me, it is where I am expressing the very best version of myself while motivating people to achieve their goals! There is no greater opportunity then coaching and cheering on individuals though their journey.
No matter the skill level endorphins welcome everyone and so do I. I am so excited to be joining the CycleFit coaching family! When I see you on the bikes/benches get ready for a fun playlist, sprints, and a sweet sweat (especially if it's upper body day-my favorite)!
And don’t forgot to bring your smiles, sweat towels, high fives, and good vibes cause we are clipped in for a good ride. Can’t wait to see you on the bikes :)
BRANDI VAN PATTEN
Starting with tumble tots and dance at the age of three, soccer at the age of five, and basketball at the age of nine, I learned very early that there is great strength and power in being part of a team. In fact, after a few years away from sports, I decided it was time to return to the soccer field, this time as coach of a middle school girls’ team. This leadership role quickly humbled me and taught me the importance of respect and accountability. To this day, I still believe my decision to coach is one of the best I’ve ever made—it’s been such a privilege to watch my players from my teams grow up and reach countless milestones.
Coaching soccer sparked my desire to earn my first personal training certification, which eventually landed me at a gym working as a trainer and marketing director. Before long, I completed another personal training certification as well as a Level 2 yoga instructor certification. I eventually left the gym to pursue a career in marketing for a global magazine publisher (to actually put my Broadcasting & Media Studies degree to good use) and in the four years since, I’ve felt the void left by no longer coaching, training, and missing out on teammates and clients achieving what they never believed was possible. When I saw CycleFit open so close to home, I knew it would be the perfect opportunity to jump back onto a team built with the intention to help others!
​
In my free time I’m typically watering my plants, buying new plants, or at Wegmans with my husband for the 15th time in a week because we always forget something on our list.
Clip in, buckle up, and be ready to party in class with me—your girl can’t resist a ride to the beat, a good dance routine, and a solid sweat!!



JESS ZEINER
Growing up, I always gravitated towards the fitness community. I used movement as my outlet through several sports all the way through high school: cheer, dance, track, etc. Being an athlete was a huge part of my identity so after graduating high school it was a struggle to leave that piece of me behind. It took a while and trying out a lot of different things before finding my new passion. When I discovered cycling, my excitement for fitness was reignited.
I am currently a full time student at Penn State, University Park majoring in Elementary Education and minoring in Special Education, Child Development, and Deafness and Hearing Studies. Last Spring I decided to combine my passion for fitness with my love for teaching by getting my ACE group fitness instructor certification and Schwinn Cycling Certification. I have been teaching cycling and muscle conditioning classes at Penn State for over a year and it is the best thing I have ever done! I am beyond excited to join the CycleFit community. I design my classes using high energy music that makes you feel like you are having a dance party. I strive to create a well rounded ride that focuses on both strength and endurance that leaves you feeling accomplished and stronger! Join me for a ride that will invigorate your body and spirit!
