TLDR; signing up for the 9-week transformation was hands down one of the best decisions I've made…read morefor myself in quite a while. They give you the tools to bet on yourself, and win. I had attempted to lose the 25-30lbs id put on for ~2-2.5 years with zero traction. I would start enthusiastically, and when I didn't see ANY results, I'd either give up completely or take my foot off the gas considerably. Then wash. rinse. repeat. I was completely hopeless and frustrated with my self and my life. Enter underground fitness. I left my initial consultation with Dave feeling almost giddy (and. don't use that phrase lightly). Everything he said just clicked - for the 1st time in a long time, it felt not only possible but likely that I would be able lose the weight. And 9+ weeks in that feeling hasn't gone away. Thanks to Dave and my Trainer Tripp (honestly one of the most knowledgeable trainers i've ever met), and despite my newly discovered hypothyroidism, I've lost 3 inches off my waist, I have the confidence to take pictures with my family/niece and even been able to bring a few items of clothing out of retirement! And all this was possible without being forced to eat salads or protein shakes all day. Dave taught me how to be accountable for myself and my food. If I want dessert, and make sure I have it budgeted into my daily calories and I eat that dessert. He genuinely cares about his clients and his only goal is for your to reach your goals, and in the process teach you how to eat for the rest of your life. Honestly, could have easily gotten double the money out of me for the following 9 weeks program but because I was doing well with my nutrition, he moved me to a less hands-on 9-week program. And frankly, Just knowing that I know how to lose the weight and keep it off and that I won't have to deal with this issue again is pretty mind-boggling.

I'm sharing this for safety reasons…read more During a squat session a few months back, I told my trainer that my back was hurting during the squats. Despite this, I was instructed to complete another set. During that final set, I injured my back badly enough that I could not walk afterward. At no point was the exercise stopped, reduced, or modified when I reported pain. I still can't squat, my back isn't fully recovered. Afterward, communication was disappointing. When my husband and I later explained that we needed to pause training due to finances, we received no response. Regardless of certification or experience level, a trainer should prioritize client safety, listen when pain is reported, and communicate professionally. Unfortunately, that was not my experience. Update: After posting this review, the trainer contacted me and offered me money to take my review down. Since he can't contact me he reached out to my husband regarding my review. I am adding this update for transparency.

I came into this journey already having accomplished a lot on my own--I had overcome obesity and…read moreeven maintained a three-year running streak without missing a single day. But I knew I needed more. I wanted to lose additional fat, build lean muscle, and truly tone my body, but I didn't have the knowledge or structure to get there on my own. That's where Coach Josiah made all the difference. From the very beginning, he took the time to get to know me on a personal level before ever introducing his program. That stood out immediately. Our communication was consistent and meaningful, and that accountability was exactly what I needed. I was able to be open about injuries and limitations, and instead of letting those hold me back, he guided me through them with a plan that kept me progressing safely and effectively. Because of Josiah's coaching, I am now at the lowest weight I've been since I was a young teenager. More importantly, I feel stronger, more confident, and more informed about how to maintain and continue improving my fitness. If you're looking for someone who truly cares, communicates, and knows what they're doing, I can confidently say he is someone you can trust. I'm excited to keep building on this progress and am grateful to have had him guide me the way.

I originally gravitated toward Josiah because of his social media content. Eventually, I decided to…read moretake a chance and work with him as my online coach, and I'm really glad I did. Josiah is not only incredibly knowledgeable when it comes to training, but he's also great at educating you on both the movements and the world of nutrition. But honestly, one quality that stands out even above both of those is his empathy for his clients and the journey they're on. Josiah understands because he's been in our shoes. He knows that everyone's journey is different, and he meets you where you're at. He's willing to push you when that's what you need, but he's also extremely encouraging and supportive along the way. Hiring Josiah was one of the best choices I've made when it comes to reaching my fitness goals. I'm stronger, more knowledgeable, and more confident because of the work we've put in together. Thanks, Josiah! Let's go!

I'm 50 years old and was looking for a personal trainer who truly understands low-impact strength training--and I couldn't be happier that I found Chris at North Valley. I visited several gyms in North Phoenix before deciding, and most of them focused on high-impact, CrossFit-style workouts that just weren't right for me. Chris stood out immediately. He offers exactly what I was looking for: effective, personalized strength training in a boutique-style environment where I feel comfortable and supported. He runs semi-private sessions that are small enough to give everyone individual attention, but he also offers one-on-one personal training. From time to time, I like to schedule a personal training session with him to focus on specific goals or areas I want to improve--and it's always worth it. The gym community is fantastic, too. There's a wide range of ages, body types, and fitness levels--and absolutely no judgment. Everyone is friendly, encouraging, and just there to improve themselves.
