We worked with Jacob for our YouTube channel many times and he is always so fun to work with and helped us achieve great results!
For one video we trained with him for 30 days and I went from 172 lbs to 189 lbs. I also was scared to deadlift more than two plates and by the end I could deadlift over 350 lbs.
Truly impressive results only achievable thanks to Jacob and his training and encouragement. You will definitely reach your goals if you train with Jacob.

Jacob was awesome letting our team come through the entire week. He allowed our Minor League Baseball team to come in and get quality training in for the week. Highly recommend if anyone is looking for a great spot to train and meet great people. Also very helpful for those who have a group or team that needs to train on the road.

Been with BIG since day one and hands down, Jacob and Nadia are two of the most dedicated and knowledgeable trainers I’ve had the pleasure of working out with. Jacob‘s knowledge of body mechanics, sports medicine and aligning workouts to accommodate for chronic injuries and overall wellness is unmatched. Highly recommend BIG for all of your training needs regardless of how big or small your goals are (they even got me to climb a mountain!)Go Bears!!!

I've been training with Jacob and Nadia for several years now, and I saw results almost immediately. They take the time to understand your personal goals and create a tailored plan that truly works for you. What sets them apart is that you're being coached by professional strongman athletes and record holders — their expertise is on another level.
Both are incredibly knowledgeable, patient, and supportive. Whether you're a complete beginner or an experienced lifter, you'll gain so much from training with them.
Their new location in Redlands is definitely worth checking out. It’s packed with all types of equipment to support any kind of workout — from general fitness to powerlifting and strongman training. Don’t hesitate to stop by and see it for yourself!

Super friendly environment. Everyone is so welcoming and friendly. The equipment they have is out of this world. And the best part, the coaches. Nadia is one of the strongest women in the world, and Jacob is a formal strongman competitor. They have so much knowledge, and experience as pro athletes and they are ready to share all that knowledge with their clients. I hired Nadia a little bit over 10 months ago, and I feel stronger than I have ever felt in my life. I'm doing things I never thought were possible. Hiring her has been one of the best choices I have made in my life. So if you are looking for a badass gym, and a coach that can make all your fitness goals a reality. BIG Speed and strength is for you 👊😎

I’ve had an incredible experience training at BIG! From day one, my trainer Nadia has been fully committed to helping me reach my goals. Whether it was building strength, improving endurance, or just staying consistent, her guidance has made all the difference.
The gym itself is top-notch — fully equipped with everything you could possibly need, from free weights and machines to specialized equipment for all training styles. It’s always clean, organized, and has a motivating atmosphere that makes you want to push harder every session.
One of the things I value most is the community. I’ve made lasting friendships with fellow members who are just as focused and encouraging. There’s a real sense of support here, and it feels like more than just a place to work out — it’s a second home.
Since joining, I’ve seen a huge improvement in my strength and overall fitness. I feel healthier, stronger, and more confident than ever. If you’re looking for a gym that’s serious about helping you succeed, with expert trainers and an amazing community, this is the place to be!

Big is the best gym that I ever worked out. I built muscle, I lose weight, and I feel good. Other gyms, I would lose weight but not build muscle. The way I did when I went to be. regrettably, I'm not able to return to big at this time, but hopefully in the future, I will get back at that gym, Jacob's experience and motivation Is what you need if you want to you meet your weight loss and muscle building goals

I am a fireman and I suffered a severe low back injury that resulted in getting two disks replaced. Unfortunately it was an extremely long drawn out fight with Work Comp to get the surgery I needed but luckily for me and my family, Jacob and Nadia helped me out every step of the way (even being long distance between us I live in Colorado.) Not only did they customize workouts to fit my limited movement but also helped me get my nutrition dialed in to insure I didn’t go into surgery weighing too much. I will be forever grateful for Jacob being concerned about my mental health and wellbeing as much as my physical health. I would and will recommend Jacob and Nadia with B.I.G. speed and strength to anyone who wants to take back their life and health. Now that I am almost cleared to start training I can’t wait for team B.I.G to build me back stronger than I have ever been!

BIG Speed and Strength has become a second home for me, my husband, and our daughter. We’ve been with them since their Fontana location and happily followed when they moved. I never saw myself in a gym like this, but I’m so glad my husband found it.
We started strongman training and even began competing—something I never imagined doing! Nadia and Jacob are incredible coaches: supportive, knowledgeable, and fun. Thanks to them, I’ve gained confidence, hit new goals, and now get to set a strong example for my daughter. We love it here!

Hello my name is Ethen Erickson I have very well known athletic background I have a great career at the division 1 level in in football FBs and FCs not only that but I have won the Arnold twice in strongman and the title California strongest man. In my experience of gym I would say BIG speed is one of the most caring and drama free gyms. The owner Jacob finnerty is one of the strongest humans that doesn’t need a belt or any fancy gear. He truly cares about youth athletes coaching both young woman and men, teaching them great work ethic and be able to achieve their goals and becoming a better person. He’s a very caring father to a young daughter who he takes care of, helping highschool football programs become elite on the field and in the weight room. Not only this but Nadia is one of the baddest woman on the planet who can overhead more then a lot of men can bench. Moral of the story if you want someone who truly cares about your life and athletic goals big is the place for you. All ages from youth to even as far as 80 I’ve seen everyone in the gym take care of the young athletes and even the elders. Truly a gem in the gym community more people need to experience.

If you’re looking for a family oriented gym with a coach that truly cares, then look no further! Jacob is amazing! He helped me through two postpartum periods and taught me what I know! He was able to help me with my nutrition and workout plan despite the long 12 hour nursing shifts! He understands the demands and can tailor your plan to suite your needs. Can’t say enough good things about BIG 🤍

Coach isn’t one to brag, but I’ll do it for him. It’s legit. You want to put in the work and be mean, lean, and strong? Here’s your gym.

Joined B.I.G a few years ago when we first moved out here to the IE. My wife and I were just looking for a gym to join with no intention of ever getting involved in the sport of strongman. The atmosphere and community Jacob has created sucked us in, and a few years later both my wife and I have competed in, and won, some competitions! With the addition of getting trained by Nadia Stowers, we feel like we’ve found our forever gym, and gym family!

BIG is hands down is the best gym in the entire IE. BIG has the best equipment, the best community there is great at helping push you to you to reach your goals, and it has the absolute BEST coaches one could ever ask for. Jacob and Nadia, the coaches, help you lose weight, build strength, use proper technique, get fitter, or train for shows, (or honestly anything you need related to fitness). The gym is focused around strongman prep and training, but is also a great place for anyone who is ready to step up their game and take their fitness journey to the next level. 💪

Best gym in socal. Came here for strongman and have learned more about strength and health in the two years ive been here than in the decade prior I spent in the gym. Jacob and Nadia are warm and welcoming but serious when it comes to training. They cultivated a wonderful gym culture and family and if you want to improve yourself and are committed to growing, this is the place for you. Jacob has helped me and many other come back to full strength and beyond after accidents, injuries, and surgeries.
Sign up and commit to yourself. You will see results, you will make new friends, and you won't regret it.

Not only are they knowledgeable, but they also genuinely care about their clients' health and well-being.
