Crossfit changed and maybe saved my life. I was almost 53 when I found Inferno. Two years later this place transformed me from a sit on the couch kinda guy. Into a sponsored crossfit games athlete. I ask you. Where else could this happen? More...

My wife and I have been in CrossFit for the last three years. We have had many experiences in different boxes around the country on our travels. We moved to SLO a month ago and dropped in to CrossFit Inferno to check it out. The coaching is top notch with an incredible base of knowledge and attention to detail. The community was immediately welcoming. Oh hell yeah! We joined almost immediately and are stoked to have a new home at Inferno! More...

So... My 3 weeks At Crossfit Inferno (California) has come to an end! 17 training session later, there has been frustrions, PBs and even unbroken muscle ups! ! I'd like to say a thanks to Bill Grundler for some brutal programming and an even bigger thanks to my top coach and Super Pairs arntner Kassi Heidemann. Everyone at the Box was super friendly and really accepted me and my metric ways! Gonna miss yas!!! Couldn't recommended it anymore! More...

The gym is located in a tucked away corner off a main street. It's a good size including one gym for the regular members and one gym for the competition team and olympic lifting. The front office is quaint and the lounge is kid friendly with plenty seats to hang out in while waiting to get into a class.Bill Grundler, the owner, is attentive to all the athletes and we were no different. He made sure we felt welcomed and during the workout we performed all our movements correctly. One tip. Some of the members we encountered were a little stand off-ish at first, but once we broke through the tough exterior, then they were ok. If you're in the area though, this would a place to drop in.

Everyday that I am able I show up at CrossFit Inferno, and everyday I show up, the feeling to want to return grows exponentially. Simply put...I love this place and the people (Infernites) that I am lucky enough to workout next to daily. I have mad appreciation and respect for all of our coaches. Bill, Dane, Jeanette, Craig, Steve, Robby, Celeste, thank you all! CrossFit is all about striving for improvement, no one cares about your starting point, we only care about your journey. What I have found to be the absolute truth at inferno, every victory or small gain you achieve is absolutely celebrated. CrossFit inferno: "If you appreciate it, it will appreciate you" More...

I've been going for the last 3 weeks, and in those weeks I have learned so much! The staff is extremely friendly and helpful in answering any questions. The trainers are very thorough in demonstrating and teaching of the techniques. If your on the fence about trying crossfit, give Crossfit INFERNO a chance, they will make you feel like family from the start. More...

Reviewing as a drop-in. They have plenty of space and equipment at this location, that is for sure. We had a class of 9 at 6:30 am on a thursday so fairly small group at least at that time. Coach Dane was great. Thursdays are their technique day so about half the class was spent messing around with box squats and zercher squats. The WOD was intense. I'd drop in again without hesitation.

I have been attending classes here for over a year now and i love this place. The high intensity interval training mixed with Olympic lifting is the perfect workout for me and has helped me loose weight inspire me to change my diet and become dedicated to my fitness and my health. The group classes offer alot of comrodery and encouragement. The trainers are very attentive and professional as well as fun to work with and learn from. I can not see my self working out any other way and i have already recommended this to several friends who have come to love cross fit as much as i do. i will continue to promote what i have come to love and have so much passion for. Thanks cross fit inferno! More...

Great experience both times! I'm from out of town and kind of had some bad experiences with crossfit. I couldn't believe how bill took the time with literally every student to make sure they were doing the movements correctly to avoid injury. He did it with such a motivating, fun and approachable demeanor. Everyone in the class was VERY encouraging and super friendly! Would highly recommend if you wanna get in shape! More...

Just got back into working out strength training again. I am impressed with Crossfit inferno. They are all very welcoming and give specific attention to form. .so much so that many  times they keep me lifting less until good form is reached.

I have been a member of Inferno for little over a month now.  I am not a tri-athelete, I am the chubby girl that can't run two blocks. ..BUT I love Inferno!  Every single member is welcoming and supportive, the trainers know what they are doing, and they are there to help with weight selection, and to give a gentle push when you need it.  You don't have to be in good shape to start out, I have seen a major change in my body and my abilities in the past month, I work hard...I am there a minimum of 3 days a week...I put the effort in, and Inferno puts the effort back into me.  No one cares if you are the last one to finish, if you are lifting 10 lbs when everyone else is lifting 100.  You are there, and you are moving...SO much better than a meat market gym!The new facility is also amazing.  There are plenty of weights, it is clean, and big...if you have been thinking of giving Crossfit a try, come on in!!!

A great feel, fantastic programming, and knowledgeable trainers make this one of the best boxes I have ever been to. I cruised over to their box to do some wods for the open and ended up falling in love with the place. The place was clean and orderly, the judges were top notch, and everything felt polished. Somehow, they still maintained a family vibe that I really enjoyed. The laid back atmosphere had me convinced to go back week after week. Couple that with a great community full of helpful teammates and you have one of the best gyms in the state. I can't say enough about the attention that Bill Grundler and his team give to their business. They even host awesome events. If you're in SLO county and looking for something close to downtown, do yourself a favor and drop in. Just don't be late!! You might have to do burpees! More...

Switching to Inferno from another local box is the Best decision I have made for my health and fitness! The trainers are attentive, supportive and thorough.

Can't say enough good things about Inferno! The trainers are top-notch- Bill Grundler is a world class athlete and the rest of the trainers are no exception. Every trainer is very knowledgeable and class sizes are kept small enough to ensure you don't get lost in the crowd.Intense WOD's but everything is completely scaleable to meet anyones fitness level. Put in your effort, and you will see results. Stronger (I made incredible gains in every category while at Inferno), faster (ran the full SLO marathon with no training runs and going to Inferno about five times a week) more flexible, more energy... It never gets easier, you just get better.To top it all off, it is not just Inferno, it is Team Inferno Family. You really feel like a member of a team and family here. Inferno sets the bar high to what you can expect from a *great* box. Work forced me to move from SLO to Tucson :(, and after trying out five separate places, no one comes close. More...

I am not a gym person, but I wanted to stay active so I can do things that I like to do. Here, most of the workout is structured in groups and pretty much supervised by expert trainers to encourage, motivate, and help you get very efficient and effective workouts that exhaust you. It is very hard work, but the results speak for themselves. Most everyone there seem very friendly and encouraging from the person who is totally in shape to the brand new people just starting out. Nutrition is promoted and all the workouts can easily.be scaled by the trainer to fit your fitness needs or disabilities that you might have. More...

I started my return to healthy living by trying crossfit. I did so under the excellent guidance of the trainers at Crossfit Inferno. I didn't know as I started to get healthy again that I would make some awesome friends and create a new workout habit that I will continue for the rest of my life. Now, almost 2 years in I have been to almost a dozen different Crossfit gyms around the country. I can honestly say this one has been my favorite. The work outs are hard, the results are real.
