Getting to Know Kelly Krauss

“When we moved to Randolph I didn’t join a gym because nothing seemed like the right fit for me until I came to Next Generation Training Center, it was full body every day with the perfect mix of cardio & strength training sessions every other day. Between the workouts and social aspect of the gym, I knew I had found my gym home.”

I moved here right before the pandemic hit and have struggled to find a gym that makes me want to go workout and keeps me coming back. I was immediately hooked when I did my trial run. Next Generation is everything I was looking for with the combination of weight training and cardio. The trainers are very thorough and make sure that you're doing the exercises correctly so you don't hurt yourself and can get the most out of it. Everyone has been nothing but welcoming and friendly; both the trainers and fellow gym members. I love the small group aspect and the uplifting atmosphere. As a retired college athlete, it's the perfect place to feel like you're part of a community again and to get that more challenging workout you've been missing. I can't recommend this place enough and I'm so happy I have now found a place I'm excited to go to!

I have been working out at NGTC for the last 6 months and it’s been an awesome experience. Every day I leave feeling like I got a great workout that challenged and pushed me. The best part of NGTC though, is the welcoming community. Small group training can be intimidating, especially when it comes to lifting heavy weights or doing new to you exercises. The trainers at NGTC work hard to make everyone, no matter the skillset feel welcome. Every workout is tailored to each individual’s needs and abilities, and the small group format means that assistance is always available. There is never a reason to feel like you can’t keep up stick with the class, because the class is designed to be modified for you. I’m really proud of the progress I’ve seen over the last few months and I’m grateful to the NGTC community for helping me feel like my best self!

Next Gen is not your typical gym. They have smaller workout groups with trainers who monitor your form for your safety and to get the most out of each workout. You feel energized by the variations of weekly workouts, gym environment, skilled trainers, and people who are there to train alongside you. Next Gen will help you with any exercise and/or nutritional guidance you need. It really is a unique place that not only cares about you, but also with giving back to the community through charities and monthly fundraisers.

I have been training at Next Gen for the last 3 years. My main purpose when I joined them was to gain strength and maintain my fitness level. The trainers are amazing and keep pushing me to the next level, even when I doubt myself! I made great friends there and whilst we work hard we also have fun!

I have been going to Next Generation Training Center for a few years and highly recommend it. The facility is in great shape and the trainers are highly skilled and alter the exercises as needed to fit everyone’s fitness level. Great atmosphere to workout and never gets boring or repetitive.

I’ve been a member at Next Generation for the past few years. Unlike memberships I’ve had at different gyms, this one I actually use!!! I love all of the trainers- they’re constantly challenging us and varying work outs, so it’s never boring. They always check in before a work out to see how I’m doing, and if anything needs to be modified during the training session. Even in a group session, things are personalized, so I know I’m getting the right work out for me. And it’s fun!!! It’s a small gym environment, so you get to know so many of the other members! Both of my children have met with the trainers there, as well, to focus on specific sports related training. It’s been a great experience for all of us! I would highly recommend to anyone interested in joining a gym!
