“This Planet Fitness in East Hanover really surprised me—in the best way. From the parking lot to the sidewalk to the gym floor, everything is spotless. You can tell they take pride in keeping this place clean and welcoming. The equipment is all new and state-of-the-art, and there’s a ton of variety—cardio, weights, functional training—you name it. Even when it’s busy, there’s plenty of room and no stress about waiting around. The vibe here is what makes it special. The staff is friendly, the members are respectful, and it feels like everyone is just here to get a good workout in without the ego or attitude you sometimes find at other gyms. Plus, parking is easy and free, which makes coming here even better. Honestly, this location nails the “Judgment Free Zone” promise—comfortable, modern, and actually fun to be at.”

“I've been actively lifting and working out for over 12 years, but outgrew commercial gyms and have striving to find a gym that has much more of a community focus these last few years - and the Garage IS that gym. This place has all the equipment and space you could ever imagine, 24/7 access, always clean and offers one of my personal favorites, which is the chance blast your own music over the communal iPad (I'm the one always blasting metal ;)). Everyone that goes here is down to earth, friendly and looking to engage with the gym goers - not to mention regularly holding events to meet up together, work out together, run together, get coffee, etc. Everyone shares the same amount of respect for the gym and one another, which is rare treat to find. Kieran has put together a killer environment for those who are passionate about their fitness and community. I couldn't recommend the Garage enough to anyone looking to take their fitness to the next level.”

“Burn Bootcamp is perfect for those who love to workout, need that trainer support and not quite sure what to do at the local gym. They have a variety of classes and trainers that are with you every step of the way. The trainers help you achieve your goal all the while providing a friendly and supportive environment. They motivate and celebrate all of the members and it doesn’t matter what level of physical ability, everyone is a winner! It’s fun, it’s tough but most of all you see results. I highly recommend this gym. Burn Bootcamp makes for a challenging but yet rewarding fitness lifestyle!”

“I can't put into words how amazing Veracity is. Some people have a negative idea about Crossfit or the Crossfit community. Veracity Athletics takes away any of the negative ideas anyone might have but keeps all of the good. I am 46 and each year I feel my fitness improves. I can write at length about the thoughtful approach for every member at all different levels of fitness but I wanted to share a story instead. Recently my father passed away and we really didn't make the service arrangements public. I looked into the crowd at his funeral and saw several coaches and members of Veracity. They are more than just amazing coaches focused on every member's fitness and well being. Their focus doesn't end at just your physical health. The coaches and members truly care about each other. There are so many amazing people at Veracity from all walks of life and all levels of success. I hope to see more and more people in the Summit and surrounding areas try Veracity Athletics. You will not be disappointed.”

The coaches are incredibly knowledgeable, supportive and always push you to be your best without feeling overwhelmed. The workouts are challenging but they offer modifications for all fitness levels, so no one feels left behind. What I really appreciate is the community atmosphere.

“Working with Diana and Nas has completely transformed my approach to fitness and health. Before I started training, I struggled to stay motivated, and my workouts were inconsistent. But they brought a whole new level of structure and encouragement that I had been missing. In just a few months, I noticed significant improvements. I am stronger, have more energy, and even my mental health has improved. They are always there to push me just the right amount and to celebrate my progress along the way.”

260 N Ave E, Westfield NJ 07090
“I'm writing this with a week of classes left before an upcoming out of town move. This review is long, long overdue. I've been doing CrossFit on and off since about 2013, having injured myself on multiple prior occasions at other gyms. I've been coming to 908 now for just over 3 years. I'm still in once piece (despite my generally poor judgement!), thanks to an experienced, observant, and just plain caring team of coaches. I'm also stronger, more engaged in working out than I've ever been, and feel more a part of a true community than I've ever felt. Leaving this place is difficult to think about; I don't think it's completely set in yet. It's a special place with special people. When you first visit you'll feel welcomed, and if you stick around long enough you'll feel loved. This is a great gym, and if you're looking to give CrossFit a try this is where you should go.”
