the people's gym
"Stopped here while visiting the area. Great equipment for any strength training program." -matthew
"Absolutely love it!! The atmosphere is exactly what I look for and need and the endless attachments, equipment and fitness toys :) makes me pumped for future workouts!" -Tiffany
"I am so glad I joined the GBOX gym. Through Brenna's HIIT Boxing and Boxing/Kettlebell Fusion I have found a new love for boxing. The Level Up class is an all around excellent workout as well. There is such a variety of classes on the schedule you will never get bored. My son and husband are loving the gym as well. Everyone is so friendly and it is such a helpful and encouraging environment." -Jessica
"the new gbox location continues to grow and offer some of the best programs around. the staff are very friendly, the trainers are knowledgable and eager to share what they know, and the environment is both motivating and encouraging. They offer a great selection of classes and I highly recommend any of brenna's boxing classes, or level up, if you really want to feel like you accomplished something. If you are looking for a gym to get started or just need a change from your current gym, you need to stop by and check out the gbox." -Chad
"awesome and it has the space and equipment that I can benefit from using." -PJ
"Amazing gym for the athlete looking to grow physically and mentally. Encouraging staff, clean equipment, in an open gym style along with knowledgable trainers." -Meaghan
"Great gym with lots of open equipment. place to go to actually work out, not just take selfies. great training staff." -Matt
"Exactly what I was looking for in a gym. They have very nice equipment: good bars, quality racks, plenty of bumper and metal plates and a nice olympic platform. The best part of this gym is that everyone who works out or trains here is motivated and friendly. It's very difficult to have a bad workout here." -Caitlin
"This gym is by far the best gym I have ever been to. The abundant different machinery and free weights allow for us to get better, faster and stronger every day. This gym is user friendly from athletes to average teens and adults looking to just stay healthy. Absolutely no judgement goes on here. Another amazing factor about this gym is the trainers and camps or solo workouts they offer. Each and everyone is very skilled and extremely friendly but push you to your own limit. Nobody here makes you feel uncomfortable and that is the best. The hours are also great, they are open from the crack of dawn to late late at night so you have plenty of time to stop in. So come in today for a free trial and join the g-box family!" -maurizio
"Very impressed, wide array of equipment to use, very friendly and knowledgeable staff. Would highly recommend to anyone from beginner to athlete." -Wesley
"Best gym in the area. Top of the line equipment and great atmosphere to go along with knowledgeable personal trainers." -Austin
"Friendly staff. Excellent trainers. Facility is a gym, not a health club! People are there to work out, not to pick up & they don't care what you're wearing." -Karlynn
"Great place to work out! I love the feel of a 'real gym!' Glenn knows what he is doing." -George
"Just took the Boxing/Kettlebell Class with Tina and Brenna. So fun and challenging at the same time! Thanks coaches!!" -Erin
"Awesome place. great facility." -Valerie
"The G-BOX is a great and friendly place! The atmosphere is awesome and the variation of workout methods make it so you'll always want to come back for more." -Roxanne
"First workout there today, equipment was available when I wanted it, I met Glenn and his GF who are great people. This is how gyms are meant to be. No contract, no BS rules, atmosphere is excellent. Give them a try, you won't go anywhere else again. I'll be there 6 days a week and actually be able to do the workouts I want without waiting for a bench or rack. The climbing rope was a nice touch. great job Glenn." -Zac
"Everything you love in a gym!!" -Bianca
"Nice gym, friendly staff that are willing to help, solid cardio equipment, awesome free weight rack, incline, decline, and flat benches, and multiple squat racks. Punching and speed bag setups in the back, and enough room to never really feel crowded. Just overall a nice setup." -Tom
"I love the G-BOX!!!! There finally is a gym that I can go to that has everything I need. The trainers are beyond qualified!! They are there for me when I'm in need. I have experienced a few of the trainers ad have had great results. They customize my fitness to my needs. The hours are great for my crazy schedule. What I love the most is that everyone in the gym is there for serious reasons which makes me feel like I can focus. They also have some great boot camp opportunities. I feel like I'm in an old school New York City gym. if you have a chance to try it out, you will love it!!!" -Elvita
"the G-BOX is the best gym around. Glenn is always so welcoming and the trainers are always around to help and are always so nice. It doesn't feel like a gym when you walk in, which I love." -Dominique
"They definitely know what they are doing, and are very helpful no matter what phase you're in. Great personal training!" -Sue
"never have i seen such community in a gym. in many gyms, or even most, i saw that members were only seen as numbers by many gym locations. you walk into other gyms, it's a quick hello and you go on with your workout. there is no going out of their way to help you. in most gyms there has been a loss of community. however here at the g-box, the biggest trait and even the trait most valued by glenn is community. the heart and soul of the gym is glenn's passion for people. he wants people to be happy and healthy by educating and providing a place for people to obtain that. along with that is the support and encouragement of other people. i have never seen a place where there is such a community where people say hello to one another, offer to help each other out and where people leave the gym with satisfaction after their workout." -AleX
"the G-BOX is not just a gym, it is a church of iron! I come here to develop a better body, release anger and just be a better athlete. All of the equipment I need is here at my fingertips. I love that I can push myself further by putting my new max on the board and urging others to beat my max. the G-BOX is a great resource and I'd love to see it go even further." -Jasmine
"The reason why I love coming to this gym is that it brings something different to the table compared to other gyms. This gym doesn't have all different fees when you join or cancel. It's good for this area because there are not a lot of gyms in the area that work with you as far as trainers. The owner of this gym is putting the name of his gym out there and he is Getting a good response. I believe in the owner and the gym and the direction it is going because Glenn has the passion for it, which I don't see with other gyms. the G-BOX is not out to make a quick buck." -Danye
"I have gone to several gyms in the Capital District but the G-BOX is by far my favorite. The staff is very helpful and welcoming. The equipment is top of the line and I'm very glad it opened up. I like how it combines lifting and boxing. the G-BOX offers an amazing atmosphere to get a great workout in." -Tyler
"the G-BOX is the only gym I have found in the central NY area that is heavily invested in both professional level weightlifting and boxing equipment. I joined this gym because of my interests in boxing as a hobby and exercise. The staff is friendly and professional." -Will
"I have been a member of the G-BOX since the beginning of February. The atmosphere is much better compared to other gyms. It is a great place to come work out and exercise. Because of the no contract and great atmosphere, the G-BOX is absolutely the best gym in Clifton Park." -Dylan
"the G-BOX provides me with a gym that has a very positive and motivating atmosphere. I always come in knowing I can get every part of my workout done without waiting around due to the various new equipment this gym provides. Glenn, Alex, and all the trainers keep the gym fun, kept up, and always push people to get better. I have recommended the G-BOX to many friends and family members and will continue. the G-BOX provides a great overall workout experience day in and day out." -Brennan
"I have been a member of this gym for a little less than a month at the time of writing this. In my short time at the G-BOX, a few things have set it apart from other gyms. I have belonged to a few other gyms in my time, but the staff and trainers at the G-BOX seem like they genuinely give a damn about the clients and want to see them succeed. I like that this gym is very no nonsense. There aren't a whole mess of things in the gym to distract you from properly focusing on a workout. It has made me want to work out consistently for the first time in a very long time. Plus, the location makes it much easier. I think the G-BOX is good for the community because it is a proverbial breathe of fresh air. It is something that I feel will give people in Clifton Park a more serious, straight forward place to work out. I think it would be great to see the G-BOX expand and I sincerely hope it does." -Ben
"This gym has not only been a great addition to my life but for the Clifton Park community. This gym has everything someone could need in a training center whether you are a serious athlete or just trying to do a little training for yourself. This gym is unlike any other gym in the area. With such a friendly and helpful staff you can tell you are not just a number. No contracts is something I have never experience before and once again you can tell you're not just money to Glenn. He takes a general interest in every members' fitness and well-being that walks through the door. I've bee burned by big chain gyms before with contracts so this was the perfect place for me. There are so many police, teachers, coaches, students, etc. that come in here, it's such a community feel in here when you're working out." -Marcus
"There is no other gym in the area like the G-BOX. Where else can you box and get the weightlifting experience with all top notch, clean equipment? As a college athlete this place has everything I need to get to the top level on the field." -Austin
"I love this place, great vibes and a ton of motivation comes with the membership. Always clean and has everything I need." -Maurizio
"the G-BOX is a completely different breed of gym. I can come here without being judged and just work toward achieving my goals. The attention to people is unmatched and I need a spotter, someone is always there to help. This is a place where I can come and get rid of stress and just lift and train." -Matt
"the g-box has become a home away from home. it's truly the perfect environment to cultivate a life change that i so desperately needed. before the g-box, i was a self-sabotaging, emotional eating, procrastinating ball on top of a mountain who needed a much to get my life back and now thanks to brenna, i'm rolling over and plowing mental and physical blocks. the pain is served daily, but with a healthy supply of support. the g-box is a judgement free zone and the first gym (out of the 15 i've been a member of) i've been comfortable in. Thank you!" -JOCELYN
"Felt welcome the second I stepped in the door. Bare-bones NYC style gym with no frills and I love that! Reminds me of college and just digging in and getting the work done. Thanks guys! So glad I found you!" -Carrie
"We were fortunate enough to stop in this wonderful gym to see Glenn Brown about 2 months ago. My wife and I had not worked out since we were married over 10 years ago and we had plenty of reservations about committing to a membership; making the no contract or cancellation fee part of our decision to give this new gym a try. Glenn and his team made us feel welcome and supported. We highly recommend the G-BOX as they provide a hometown feeling that you may not find in the national chains." -Whitney
"not your average gym. glenn and team helped motivate me and regain my interest in my fitness after a long hiatus and many failed gym memberships. personal training sessions are a must if you're getting back into working out. equipment is state of the art and the innovative equipment helps keep workout routines interesting and different. no long-term contract needed but once you get started, you won't let yourself quit!! I highly recommend you check this place out." -SCOTT
"Awesome gym! Owner takes care of the facility and makes sure to keep the gym in tip top shape! No contracts either!!! Highly recommend!!" -Heather
"Training at the G-BOX is a life changing experience. It not only changes you physically but also sharpens and develops your mentality and outlook on everyday situations. What a place!" -Giulio
"Spoke to the owner once, and have a great first impression. I can't wait for my first workout!" -Daniel
"Awesome trainer - Awesome workouts! Love it here!!" -Grace
"First session and I loved it! great workout and super supportive staff." -Ronnie
"This place is unlike any other gym I've seen before! Awesome! You have to check it out!" -Marcus
"Every workout is intense, and I have never seen results so quickly. Such a great workout, so encouraging! This place is going to be like no other gym!" -Alexandra
"I love the site, the training is great and I highly recommend Glenn and the G-BOX staff to all!!" -Giulio
"The best personal training ever!! Check it out!!" -Elvita
