HIIT BK

Marc is absolutely one of the best trainers I have EVER worked with. He pushes you past your limits at every workout. I started HIIT BK through Classpass but I buy extra classes through the studio because it is a guaranteed great class. You never leave feeling like «I could have pushed myself harder». Marc doesn’t let you get away with any slack. This is comparable to a Tonehouse workout but has way better music and Marc is better than the Tonehouse instructors (I think). Magic happens at HIIT! My body has definitely changed since doing HIIT BK. It is the most effective workout I have ever done and the most fun!

I have worked out at a lot of studios around NYC. Of course, this isn’t a studio with tons of amenities, but isn’t the workout more important? Today was my first class with Marc and he truly was the perfect mix of tough, motivational and understanding. If you need help with form just ask him. But you’ll def get your heart rate up and break an excellent sweat. If you don’t like loud inspirational music then maybe you should take a nice quiet run in prospect park or a yoga class… But the music just added to how quick the time went by. Thanks Marc.

Classpassed a few times around the holidays and it was a great workout each time. It’s a group HIIT class so you can pace yourself as you need, but I thought Marc was attentive (and a little like a drill sgt, in a good way) at just the right times to keep my lazy ass moving.
I see some reviews complaining about cleanliness, organization, or attention to form… who am I to argue with them? This is just one opinion from someone who has been to several different studios and really enjoyed the fast-​paced, challenging workout with good people. I found the studio to be clean, the class to be well-​led and the attention to form was good enough for people with basic experience doing body-​weight exercises (there wasn’t anything else in the classes I took). Maybe its not the most inviting for someone who has never done a squat before but Marc is such a nice dude, just show up a little early and let him know you need to instruction! He’ll definitely help you out.

Exceptionally loud music after hours on weeknights comes from this «fitness» center. No sense of civic responsibility. Can hear the so-​called music they are playing crystal clear inside the Red Mango down the block.

I used to love classes here, but went recently and can’t believe the change. Emphasis was placed on more weight rather than form, instructor Marc was outright screaming the entire time and there wasn’t an organized flow to class. Used to be one of my regular spots, but disappointed to be looking elsewhere now.

The Total Body HIIT class is killer. I’m incorporating more HIIT into my fitness routine and HIIT BK offers a great workout, with little to no rest time in between. I wouldn’t say this class offers modifications so if you have a bad knee or something you need to be careful.
In my last class, we cycled through 3 exercises for one minute each and then repeated that 3x, and then started a new cycle, followed by an intense sequence of fast knees and burpees (ugh), and then we broke up into groups and did various circuits. We ended with a quick abs portion on the mat (I only wish this part lasted longer). It’s tough — on a scale of 1 to 10, it’s an 8. As a reference, Tone House is a 10. I like that the class works out your entire body, and you leave feeling super sweaty and accomplished.
If you don’t mind a burly man yelling «WORK!», «YES!» and «LET’S GO!» at you throughout class (because he does, and it’s crazy how he doesn’t lose his voice) and making you do more burpees and push ups than you ever thought possible, then come try it out… and leave your ego at the door. Marc, the instructor, will make you work hard and doesn’t let you slack off. In fact, he may come over and push you into a deeper squat or stand over you while you shake in a plank. This approach may not work for everyone, but it works for me!
For the first time in forever, my boyfriend and I have found a workout we can enjoy together. He admits that this place kicks his ass. The studio is truly no frills (and the bathroom could use some fixing up!) but that’s okay because you’ll get a tough, challenging workout and that’s all that matters.

Great workout! Steven is amazing, he motivates you to do the most you can. I felt super sore afterwards. will definitely be coming back

Went here though classpass. The classes are no joke and really good, it sucks in the moment but you feel that much better after. I would characterize it as more like 10−20% fight boxing and 90−80% fitness/​cardio. I was expecting more fighting work technique but the class was still great regardless. I did of bunch of other ‘hard’ classes though claspass and this was the most intense. Yeah, the place is no frills and NOT fancy but thats how you know fitness is the first priority there.
My only suggestions. Music is constant hip/​hop, personally I don’t mind but I also like a mix of punk, metal, rock. I wanted to sign up for another class when my claspass was done but the website dent just show a price, and you have to create an account, ugh, maybe its just me.

I checked out this place through Class Pass while visiting my brother in Brooklyn. I was excited at the chance to get a good interval workout in while on vacation (thanks Class Pass!) but my experience here was decidedly mixed.
The positives:
— The workout was intense, challenging, and involved a wide variety of movements.
— The instructor was relatively attentive to form.
— The instructor explained the logic behind some of the moves and combos in terms of exactly how they help your endurance and strength.
The negatives:
— There was absolutely no warm up. As a result I pulled a quad muscle quite painfully while doing lunges while holding a weighted plate above my head some ten minutes into class. This is inexcusable for a class of this intensity. As a former fighter who trains every day people the instructor must know better than to dive right into technical and challenging moves with no form of mobility work or warm up before hand. I wanted to like this place and the lack of warm up ended up ruining the experience quite painfully for me.
— The instructors tone was alienating at times. He asked me if I played basketball while I was panting and doing calf raises and when I responded «No, I play ultimate frisbee,» he sharply retorted that «You don’t need your calves to throw a frisbee.» I don’t knock anyone for not knowing about ultimate frisbee (it’s a somewhat obscure sport I get it) but as a fitness instructor it behooves you to be welcoming and inclusive not dismissive of your students other forms of exercise. No need to make people feel out of place.
Overall I would say that this is a solid studio with some issues in how it packages the exercises and the experience If they add in some form of workout and don’t make new-​comers feel weird for showing up this could be a really solid studio. Worth a visit if you like high intensity interval training and are in the Flatbush area. Just make sure to warm up thoroughly beforehand as you will not be spending any class time on this!

This place needs more reviews because you really get your ass kicked in this class and I mean that in the best possible way. Everyone is super nice and supportive and every workout helps make you stronger physically and mentally. My favorite is the Massive Hit because it’s all weights and it really helps you push yourself and become strong.

Mike is the man. I’m writing this after taking his class last night because my abs hurt when I laughed. This is no easy class. You will sweat and you will be sore. That’s what I’m looking for and appreciative of. Can’t wait to go again!

Fantastic spot to get a great workout. If you’re looking for the high end amenities, go pay a personal trainer $ 100+/hr or go to Equinox. If you want a solid workout that pushes you, without injuring you, here’s the spot. It’s a great option for small group «semi-​private» training as well. The classes rarely get over 8 people and many times can be 3 – 4 at 6am so you always receive ample attention.
Mike and Jimmy both lead fantastic classes. They push you to your max, without doing exercises they couldn’t do themselves. Mike does all of the exercises with you, and demonstrates proper technique before each one. Jimmy demonstrates the exercise properly, but provides more vocal encouragement throughout — at 6am I’d rather have that approach.
While the space isn’t huge, they have a downstairs area with additional classes. You rarely feel crowded, and the mats provide good cushioning when you are doing various exercises.
The pricing is quite fair, and they provide discounts if you get larger 10 or 20 packs of classes. If you stick with the program, go 3 – 4 times a week, you will definitely see results. The pace of the class is fast, enough to keep your heart rate far higher than most folks ever get to at the gym. Give them a try, you won’t regret it.

Mike gives a great workout that makes sense. That phrase may sound strange but really think about… have you ever had an instructor that made you do stupid exercises that yes did get your heart rate up but weren’t designed to strengthen you the best way (e.g. sit ups and then bicep curls). Well not this class, the exercises are molded so you really are toning your body with logic.
I’ve been to Saturday’s HIIT workout and it’s broken down into the circuits. One that targets the whole body, one upper body, and lower body. Well technically they all work out the whole body but each circuit focuses on a major part. There’s strength training with weights, squats, and always a cardio exercise to rev up the heart rate like burpees with pushups and squat thrusts.
The classes is very challenging and windows are completely fogged when the class is over. Mike will come around and give people an extra challenge… like pushing you down while you’re doing a pushups!!! Yes killer. Although I always push hard in class and hate when people hold back, I’m not gonna lie I do hope he passes me sometimes when he comes to give an extra challenge cuz they are some of the worst seconds of your life. Haha. But overall he’s great, you should go.

Holy shit. This class kicked my ass.
The space is pretty minimalist, but I’m okay with that. I’m here to get my burn on, not to enjoy waxed hardwood and marble sinks in the bathroom. The workout is conducted tabata-​style, meaning 20 – 50 seconds of your max effort followed by 5 – 20 seconds of rest. This means that your heart rate is elevated the entire time. Personally, I felt like my heart was going to beat itself out of my chest and run screaming for mercy down the street.
I took Massive HIIT, which is a weight-​based workout. So things that are already tough — squats, burpees — are made even harder by adding 5, 10, 20 and 25 pound weights. I couldn’t believe how tough it was with the added weight, but Mike really pushed me to my limit, and as a result, I felt like I got one of the best workouts I’ve gotten yet in the city. Mike is a great motivator with just the right touch of tough love I remember well from my cross-​country and swim coaches back in high school.
Oh, and the feeling you get when it’s over, when you walk out into the cold covered in sweat with your muscles quivering — is there anything better than that?
I’m still sore. But I’ll be back.

Best neighborhood gym! The workout is the best in NY if what you are looking for is to get strong, burn fat and work hard. I went with classpass the first time and I got hooked right away. Mike knows his stuff and pushes you like no other instructor.
Now I dropped classpass and bought a monthly membership. I tried many strength training studios with classpass and there’s simply no other gym that gives you this kind of workout and makes you feel so good afterwards (even after being sore for a day or 2 you can’t wait for the next class).
A note of caution based on other reviews: it is not a fancy gym like others in Manhattan with iPads, front desk and complimentary massages. It’s all about working your a** off. If that’s your goal you’ll love it as well.

I booked a class here via classpass before reading these reviews so obviously I was a bit nervous.
I went in and started knocking the place immediately. It’s one room with cubbies by the door. No reception area and no receptionist. I was there for a few minutes before I guy came from the back office to tell me that the bathroom was across the way and the changing room was downstairs. He went back to his office and I waited.
The space is not fancy at all. They need a new paint job and new bathroom accessories and new equipment.
With all of that said, the workout was awesome. Push-​ups, burpees, mountain climbers, boxing. A great sweat session.
They just need new boxing gloves. The ones they have are FUNKY!!!

Booked through ClassPass, was very interested in trying them out as it looked exactly like what I wanted on top of my regular regimen. Since I was ditching ClassPass soon, and was looking for booking a 10 or 20 class package to prepare for a race, HIIT BK seemed like a good, affordable place to up your cardio and strength. Despite some negative reviews regarding no-​shows, I went ahead and booked for a morning class.
The storefront was closed, lights out and everything. I could’ve slept an extra hour, and could’ve avoided running to the train to make it on time for the appointment. In conclusion, the reviews that addressed trainer no-​shows were very valid. Pretty lackadaisical spot. I don’t think I’m laid back enough to show up early to a closed gym on a work day morning.

Great workouts, supportive community, and dedicated staff! The facility may be a little rough around the edges but that is not what is most important to me.

This workout is the biggest secret in the city.
What makes it so great is that it works on every level. The workouts are very scalable, the instructors are helpful on the techniques, and there’s a real camaraderie with the people here. Everyone’s genuinely positive and encouraging. There’s a good mix of people at different levels too, which I think creates a pretty non-​intimidating class.
The workout itself is 1 hour, tabata style, with weights, cardio, and boxing gloves/​heavy bags (you can even borrow gloves if you need). The exercises are geared toward working out a few muscle groups at a time, so you get the most results in the shortest amount of time. There’s a focus on conditioning and self defense as well, which I really like b/​c living in NYC, you never know what could happen out there, and most criminals won’t be training anywhere near as hard as you’ll be in this class :)
The space is clean and fairly basic: workout studio upstairs and downstairs, couple of bathrooms, showers, cubbies for your belongings, towels and cleaning alcohol. This is not a spa-​gym and personally I love that it doesn’t attract those pretentious types. It’s a small local business and the focus is really on giving you the best workout possible. Mike, the owner and main trainer, is awesome. Very positive and motivating. He even does the full workout with you. And you know you’re getting a great workout when you see him struggling right along with you, and he’s all huge and ripped from doing these workouts probably 6 days a week.
As 1 other Unilocaler has pointed out, there was a trainer not showing up for classes, but he has since been fired. In all the classes I’ve been to, there’s always been a trainer there – on time and enthusiastic. So this isn’t an issue anymore.
If you’re looking to try something new and get results fast (you’ll be easily burning 700 – 800 calories in each class), check it out!

I’m editing my review below (previously 2 stars) as I did give it a second chance after a friend raved about Mike’s class. I’m glad that I did. The trainer Mike makes HIIT the success that it is, as you can see from the other high reviews. He’s motivating, inspiring, and pushes me harder than any trainer I’ve had before (and I’ve worked with a lot). I also like the mix of people in class – there’s a little friendly competition, but people are friendly and supportive, and classes have a great energy.
My negative review below was about Nick.

Prior review:
My concern (and the reason for the 2 stars) is the lack of professionalism. I’ve shown up for classes (both drop in and reserving online) only to have the instructor not show up. Making matters worse, no one has responded to my email or call to receive a refund. I’m disappointed by the lack of professionalism, and I won’t be returning.
As someone who vigorously works out 4 – 5 times a week, the workouts are solid – a great mix of cardio and weight training.
The space it definitely rough around the edges – only water supply is from a faucet and the bathroom is a little sketchy.
