It's impressive how everyone seems to become fast friends in just a single day, and I'd love to be one of the regulars they recognize, too. I was especially blown away by the owner's attentiveness.

Blaksteel has been in this little strip mail near Camelback and 40th St for years, as long as i can remember. it's a smaller gym with smaller crowds and classes. i mean, if you're looking for an Orange Theory or Lifetime gym experience, this isn't it. meaning it's not glossy or pretentious. there's no poolside DJ. (there's no pool.) it's a "do the work" kind of place with really good instructors. imo, that is to say, it's not a place for everyone. if you're looking to make gains, achieve results, this is the place for you. really nice to have a business like this in the community. at minimum, if you're into fitness, it's a good place to give a try.

This October, it will be two years since I've been coming to KBX and it has truly changed my life…read more I always tell my friends and family, it is like second therapy. However, the beginning of this year I become complacent and was really only coming to one class a week and making a lot of excuses to not do more. My physical and mental health were definitely being affected, so I decided to sign up for the six week Boot Camp. I'm not gonna lie, I was pretty intimidated in the beginning, but I really wanted to challenge myself, reset some habits, and overall get back to something I really enjoy. The six weeks helped me get back on track with my hydration goals, eating healthier, and going from one to maybe two classes a week to some weeks doing 5 to 6. Ultimately, it helped me recognize that with some small steps and keeping focused on my goals I was able to make some real change. What I really enjoyed as well was it really was designed for each individual person to go at their own pace. We had a group chat that constantly encouraged each other, shared recipes, and motivated each other on the bad days. It was about the small wins, and always going back to our health is beyond the six weeks. Yes, I saw results and that definitely helped motivate me to keep going, but really it helped me recognize that I want to be a healthier whole person and in order to do that I need to show up for myself. I may not now be doing 5 to 6 classes a week, but doing 2 to 4 is absolutely manageable with my schedule. Thank you so much Joe and all the support you gave each of us during Boot Camp! Your guidance and encouragement definitely made the whole experience! If you haven't done a class at KBX yet I highly suggest you do it! You will not regret it.

You wear a heart rate monitor and it calculates your heart rate and all kinds of other information which allows you to adjust your workout in real time.

The coach was fantastic. They have a full locker room with showers. Unfortunately, the lighting in this space gave me a migraine and I won't be able to go back(orange lights mixed with natural sunlight).

I have one athletic gift, only. And it is odd. I can run up hills…read more It's a slog, for shiz. It's almost comically sluggish if you watch me do it alone. But when head to head with the average Joe, even Mr. No Shirt, Pristine Tan, Joe Six Pack Abs, I can usually sloth-jog to the top of a hill faster. And trust me, male or female, young or old, if you're on one of the valley hiking trails at the same time I am, we are fucking RACING. Even if you don't know it. Even if you laugh at my paunch and short shorts and their biting incongruence with even the most generously interpreted mores of polite society. Even if you don't care. You're on my radar. I am hunting you. If today were a 1000 years ago, you'd be dead because I'd catch you and kill you and probably eat or try to eat your brains. You're from another tribe and you are meat. Note: I will leave you be when you exercise with Matt. My hiking, no surprise, is in no truly logical way related to The Jarvster. However, I believe in metaphysics and quantum mechanics and with what little additional I understand of string theory, I know, capital K Know, that EVERYTHING is related. So here's the illogical flow that quantum leapt me into the (dis)abusive relationship I now find myself enjoying myself in with ("I wish I knew how to quit you!") Matt Jarvis: When one can run up hills, one thinks they're in shape. At least decent cardiovascular shape. And then they are introduced to Matt Jarvis, by a loved one no less, on a shiny Saturday morning, where they have to sit down perfectly still in the middle of class because they're going to puke. Now, don't mistake my almost puking with any sadism on the part of Mr. Jarvis. Instead, assign it to the frailties zigg-zagging through my life force, which my perfect specimen of a lady friend must endure because I convinced her I was worthy of her love. Which is to say I'm not in the shape I thought I was in. And pushed too hard. My bad. He didn't make me feel like an asshole about it. At all. Out of all the trainers and yogis and typologies of exercise endeavors I've tried throughout the years, including all of them, nothing has made me as sore and perplexed as Matt Jarvis' training program. It's fascinating, really. In one now infamous moment during the middle of an exercise resembling Spiderman crawling up the side of a building, I explained to Matt that I understood, based on my body's reaction that the exercise was, in practice, difficult, but I couldn't for the life of me explain why. This is the thing. I feel like nothing is too crazy, individually. But his workout has this additive effect that I've never experienced with anything else. And I think it's probably the most genius exercise regimen I've ever encountered. Eight-fucking-day soreness. Tell your mom about that shit. It's real. It's chariots of fire. It's Rocky. It's amazing. You can stop reading here if you're trying to decide whether to use Matt as I have said my peace but I have a couple more things to say. My girlfriend, who has been training with Matt longer than I have, does more weight than I do... Which is only emasculating insofar as I happen to know she is attracted to muscular arms, which I do not have. Which is where Matt comes in. Except she exercises with him more than I do so her arms keep getting stronger. And the cycle continues. Someday. Pray for me. Also, I want you to think about personal trainers in the following manner: 1) drill sergeant; 2) loving father figure supportive character; 3) tomboy with the exceptional body who is ambiguously lesbian; 4) dude who's on his phone when he should be spotting you; 5) meat head who, while muscular, is not cut in any way; and 6) truly inspirational character who needs his own television show. Matt is 2 and 6. Sometimes, when I'm trudging up the mountain, I think, Matt's going to be so proud when I can get through x,y,z exercise without having to go rest in front of the fan. Or gulp water. Or cry silently. There is no judgment. He's conversational. His workouts are like ASU. You can go there and party your ass off or you can work with Nobel laureates and change the goddamned world. Totally up to you. The opportunity is there to change your life. Do it for me if not for you.

I had no energy, I topped out at about 335 pounds or so, I pretty much just hated myself and my life. During the time I worked with him I went from this no energy, tired state weighing in at 6'1" 40% + bodyfat to a lean 215 pounds, 11% bodyfat. More importantly, Matt worked with me on a level that proved that he was a good friend and mentor. That he had a vested interest in my results beyond just profit. I can honestly say that he was instrumental in changing my life and I can't possibly express my appreciation in words. The guy gave me his old mountain bike when my car died. Five stars? I'd give him 5000 stars if Yelp let me...no joke.
