Amazing place. Feel so much better with each work out. The trainer that I have really cares. When I have used back up trainers, I have similar experience. Very impressive that they all have a system that they follow that works.Jake, Ariel, Tommy!!

I’ve been training at Serious Strength with Tommy Day and must say I have never felt stronger or healthier. I’ve been a yoga practitioner for more than 30 years so I’m no stranger to exercise, but Slow Burn under the guidance of Tommy, has made me feel more fit than ever. He is patient, instructive and encouraging as well as knowledgeable. A true mentor and source of inspiration.

I have been going here for several years. It is very time efficient and most importantly EFFECTIVE! Probably the best weight training program around. Also every one of the staff is great.

I have been training in slow burn at Fred’s studio for the past 4 years. Fred has created a scientific body building technique which is highly efficient, injury free, requiring no more than 30 minutes one or two times a week, allowing the body to both fatigue and recover according to its natural rhythm. The studio is kept spotlessly clean, the trainers follow Fred’s method meticulously and maintain a log of their client’s progress on each machine so it is clear how one is building strength over months and years.

Tried this little hole in the wall to see if you get better results than at a regular gym. Not at all. The technique is slow, but nothing you cant do yourself at a regular gym. Noticing how Fred treats his trainers - I would not recommend this place to anyone.

I have been going to SlowBurn in Montclair for over a year now and the results have been amazing. I had some baby weight around the middle that I wanted to get rid of and I am a busy mom who also runs her own business so TIME is not on my side. Doing SlowBurn paired with intermittent fasting allowed me to go to my SlowBurn workout once a week and see results! I love both trainers Tommy and Rosanne and I feel like they honestly do care about my progress. Oh and I love those jerky sticks they sell too for a post-workout treat!

I’ve trained with Fred for many years because his slow-burn program works. My weekly 30-minute training sessions have helped me remain in excellent physical shape as I’ve gotten older, an age-defying physicality that my friends often comment on. And I love the fact that at Serious Strength, failure (i.e. muscular fatigue) equals success (i.e. muscular improvement). It is the only thing I’ve ever done in my life where I’m focused on achieving consistent failure.

I began training with Fred Hahn when Slow Burn first opened and have never looked back! I began training to strengthen my back after surgery and havent had to visit a chiropractor since. I could soon see increased strength and endurance in doing every day tasks, like walking up 3 flights of steep stairs to my 4th floor apartment with bags of groceries! I have lost 10 lbs. and at 62 am in the best shape Ive ever been. My increased muscle mass makes it so much easier to keep the weight off. If you train at Slow Burn, youll never have to spend hours in the gym again, AND get a better result...youll never regret it!

Ive done 3 training tours with SloBurn and paid close to 10K in the process. All was going well at 2 30 minute sessions weekly....until I recently got sick with the flu. I had paid in advance for each block of my sessions. As the sickness progressed past a Z-Pac, I got better for a day and relapsed. In spite of calls to SloBurn from me, and from my roommate (who I also referred there), this organization went into my bank account and withdrew money it was not owed. Remember I PAID IN FULL IN CASH AT COMMENCEMENT. When I called the receptionist literally laughed at my raspy voice and defended the unauthorized bank withdrawl, saying well you canceled 3 times. Understanding shes a young person having just started the job, I asked to speak with, the owner, Fred Hahn. After waiting 5 hours for his call, I called SloBurn main number and left a detailed voice message specifically for Fred about the un-owed and unauthorized bank debit. He had not returned my call by 9am so I called back and left another call back request. To wit, he said I had to understand he was losing money because his trainer had to be paid for my absences even though I paid already in advance for my sessions. I informed him of my unhappiness with this attempted double charge (sickness tax!), and that on principle I wanted my bank account immediately refunded. He said I was no longer welcome at SloBurn studios and hung up on me.So beware those persons I have referred and those who have become customers for if you get sick and it lasts past the allotted timeframe Fred thinks you should have recovered within He will take carte blanche with your bank account....and never even wish you a speedy recovery.

Great exercise
