I’ve been training with Zack Niziolek at Lifetime Chestnut Hill for a little over 2 years and cannot recommend him highly enough. He is so knowledgeable about strength training, fitness and nutrition. He is the perfect combination of challenging and supportive and I’ve reached fitness goals that I never imagined. I’m the strongest I’ve ever been and the most committed to my own health. I’ve done both individual sessions with him and partner training with my best friend and it is always so much fun and I look forward to every session. He is motivating, creative, focused, accessible, funny and able to answer any question I have. He always makes you feel comfortable yet pushes you to achieve more than you imagined. I recommend him to anyone - 10/10!

I love Alpha classes ! I have been going about 5 -6 times a week. The coaches are extremely helpful and knowledgeable. I’ve noticed a huge improvement in my strength. I take Zach, Andrew & Max’s classes during the week. I have nothing but positives about all the coaches definitely worth a trial. All movements can be modified depending on experience and you’ll be leaving feeling stronger and more confident.

I've been training with Phoebe Liu for over a year now and I can not recommend her enough! Her class is always challenging and we almost never do the same thing twice. She is extremely dedicated to getting her clients to the strongest and healthiest version of themselves- 10/10!

I would like to thank Phoebe in helping me strengthen my core and balance through Pilates. I study martial arts and was having difficulty in activating deep core muscles needed for certain movements. Phoebe helped me feel and engage these muscles. I appreciate and am thankful for her skillset to help me accomplish this goal. Many thanks

To be honest, I was a little intimidated by the thought of working with a trainer at first, but I did it anyway because I had goals but wasn't sure how to meet them. I first started working with Cameron in August 2022 and from the very beginning, he was extremely friendly and kind and put me at ease right away. My initial goal was to become stronger overall and he took this very seriously. He had so much knowledge and shared everything he knew, from nutrition tips to effective workouts, and even down to his favorite protein powder! As I became more comfortable with my workouts, my goals started to evolve. As soon as I let Cam know, he shifted gears right away to accommodate these new goals in the best way possible. He was very flexible and adapted easily to my needs and restrictions. Overall, Cameron is extremely empathetic and knowledgeable, and he truly cares for individual clients.

Have been working with Sam in 1:1 personal training since December and it has completely changed what it means to be healthy! Sam has worked with me on increasing strength, building stamina and adjusting daily nutritional intake. I am in month six of training with Sam, and there is a significant increase in muscle, loss of fat and just an overall sense of feeling more healthy. Sam is excellent hearing what my goals are and creating a individualized experience that helps me meet/exceed these goals. I am grateful for her and the work we have done the last half year together!

I had the pleasure of working with Zac. His expertise and knowledge in fitness and nutrition were evident from the start. He provided me some specific goals and improved my form. His varied and fun workouts kept things fresh. He is very professional and passionate of what he does. I highly recommend Zac as a personal trainer to anyone looking for outstanding results and an incredible fitness journey.

Zachary Niziolek is the consummate trainer with experience and dedication who provides you the tools to help you improve. His interests in strength training, work out routines, and sports herald back over decades. His ongoing evaluation of your posture, stance and form provide the foundation for a sound work-out. We even cover appropriate breathing technique. Each session is created specifically for one’s own physical requirements and capability. I have had over two years of instruction. Each session is tailored to different muscle groups to emphasize. They vary so that the interest level remains high; it also keeps it challenging. If you want a specifically calibrated routine, exquisite instruction, and valuable encouragement, Zach is a five-star instructor. I have had multiple personal trainers over the decades, and Zach excels due to his extensive knowledge and the creation of an ever varying routine design to improve fitness, health and strength. You will become the best that you can be.
