Liz Gilinger - Owner of CoreFit,LLC I have been in the fitness industry for the past 20 years, teaching aerobics, personal training and finally competing in several figure competitions at the age of 40 - I truly believe it is never to late to start a fitness program. I love functional and core training and continually search for the cutting edge programs available. That is when I discovered Kettlebell Training, it is by far the BEST results-oriented workout I have come across since I have been in this business. Deciding to get certified, there was only one organization that I would choose - The RKC - and with good reason. What an amazing journey the RKC has lead me on, the program is incredible and the certification and training is like no other in the industry. The results I have witnessed are amazing, from the rehabilitation of injuries in my own body to the UNBELIEVABLE results that my clients are achieving. This motivates me to make sure everyone I come in contact with learns this old age/new way of training. The results speak for themselves. CoreFit Kettlebell Training offers Kettlebell Group Classes, FMS Screenings, as well as one-on-one training, in the Collegeville/Phoenixville, PA area. Please visit my web site or contact me directly for a free trail class. Guaranteed you will love this workout and you will see results.

10/10 What a difference the right instructor makes!
By Jennifer Connelly / Collegeville, USA

I love working with Liz! I started working with her about 4 months ago and am seeing tremendous results. It was great having the ability to work with Liz practically one-on-one while learning how to use the bells properly to avoid injury. She is ever watchful that her members are using the correct form while pushing us to work harder. I leave her classes feeling energized and strong! The workouts are always different so I never get bored and always feel like I have worked every muscle in my body! Liz is a great motivator and her knowledge and experience is invaluable.

10/10 Tough workouts... great results.
By John Russo / Schwenksville, United States

Liz, and the entire Corefit team, have introduced me to kettlebells and now I am hooked. The workouts that Liz has created are intense but she keeps everyone going and enthusiastic. Liz focuses on form to keep the workouts very effective and safe. I have recommended others to CoreFit and will continue to do so.

10/10 Persistent disk issues remedied
By Bob H. / Collegeville, PA, U.S.A.

I was a traditional gym rat - 20 years of weights & cardio. A herniated disk forced me to re-think how to achieve my fitness goals. Despite heavy pessimism about kettlebells - I was actually concerned it would make my back worse, not better - Liz convinced me to give it a try. Frankly I've been stunned by the results. My back no longer bothers me, and in fact feels stronger than ever. What's more, the workouts are as much fun as they are effective. Liz creates an atmosphere that is comfortable for everyone, and at the same time she manages to understand all of her members' unique issues and needs. I have recommended CoreFit to several of my friends, and they have had a similar experience.

10/10 Liz and CoreFit-Intense and Rewarding!!!
By Martina / Phoenixville

Meeting Liz was the best thing that has happened to my body!

She is super friendly, motivating and knowledgeable, as are all the instructors. As an RKC and functional movement specialist, she knew exactly how to fix my problem areas without incurring further injury, which was a concern after 6 months of physical therapy. All this with kettle bells!!! Liz worked with me privately and quickly moved me into classes. They are very challenging, but very rewarding as I have noticed results in a short period of time. Classes include KB, TRX, cross fit, yoga, zumba along with other toys such as tires, sledgehammers, sandbags etc.
CoreFit's motto-twice the results in half the time-IT'S TRUE!!! You need to try it to believe it (they even offer a complimentary class). The class sizes are small so you always have a great instructor there for you, but the members :) are always there as well, encouraging and supporting you in the best way possible.



10/10 The best workout I've ever done
By Jessica Reigner / Collegeville, PA

With three small children and a full-time career, I need to make the most of the time I have to work out. With all the workout regimens I've used, by far, the kettlebell training I've been doing has gotten me the most results in the fastest time. What a total body workout and I feel great. I notice a huge difference in my arms, abs, and rear after 10 weeks of regular classes - down over 8 inches! Liz goes above and beyond to focus on form and me as a person - checking in with me outside of class, caring about my overall health and diet. I feel challenged and I'm so grateful I found Liz!

10/10 Kettlebell has changed my attitude
By Giselle / Collegeville Pa

I came to Corefit over 50 years old, overweight, and having limited exercise. I was desperate to try something that would click and allow me to make lifestyle changes for myself and that I could stick with. What a change kettlebell has made to my life. I have lost 20 some pounds, more than 20 inches and have a new attitude about exercise and what it means to my life. I have gained a new appreciation of what good health is and a sense of satisfaction and accomplishment.
Liz, Lena, Kim, and Tracey at corefit have made this transformation possible. They are super instructors that provide encouragement and "tough love" so that you do not give up. Without their instuction and guidance I would not have continued but somehow they have given me the strength mentally and physically to continue. No one is told old to make this transformation - Corefit and kettlebell is awesome.

10/10 Motivate & Challenge; Keeping it New and Fun
By Steve Westfall / Phoenixville, PA

Liz, Lena and all of the CoreFit instructors have opened the door to a new level of physical and mental fitness. I followed my wife into kettlebell training over a year ago the goals of increasing my strength, toning my body and improving my endurance. With the help of Liz, Lena and their team, I have met and exceeded my goals.

I am not a gym person and it was important to me that any fitness program that I committed to provided supportive guidance, proper and safe instruction as well as ongoing monitoring. At CoreFit, the instructors teach, coach and encourage and it is clear that they know what they are doing. They motivate and challenge but keep it fun and interesting.

By Lauren Tornetta / Phoenixville, PA


Although I have not known Liz for long she, through COREFIT Kettlebell, has made great impact. Liz is dedicated to high performance classes and celebrates individual and team successes. Liz is committed to ensuring proper technique and working the entire body to its full potential EACH and EVERY work-out. Finally!! - I have found a great atmosphere in COREFIT and have 100% confidence in Liz's ability to motivate my mind and body. After three weeks, I have seen noticeable changes in my strength, conditioning, and flexibility, which is no small feat after just having a baby! Liz is an instructor who truly shows the highest commitment to Kettlebell training and quality instruction. Liz's desire is evident by her creative and challenging workouts. She keeps the classes fresh and is well aware of her client's 'make-up', thus knowing how to build strength safely and progressively, as well as knowing when to 'push the envelope' for a true gut-wrenching workout!

10/10 Awesome workout!
By Kelly / Phoenixville, PA

Kettlebell classes are addictive! After spending three months on strict bed rest last year, I lost all muscle tone. I couldn't walk up a flight of steps without feeling out of breath. After my twins were born, I needed a workout that targeted cardio and total-body muscle toning in the shortest possible time...I no longer have time for long monotonous work-outs. Liz and Lena are incredible. They are truly dedicated, motivating, and supportive instructors. Every workout is challenging, and no two are the same. They are always there to help improve your form. Welcome back, pre-pregnancy body (thanks Liz and Lena!).
