I am writing to express my sincere appreciation for Caden as a personal trainer. My wife and I had…read morethe opportunity to train with Caden for approximately six weeks, and the experience was exceptional. Caden has a unique ability to motivate and challenge his clients to achieve more than they believe possible, while always ensuring workouts are safe and injury-free. His knowledge, professionalism, and genuine investment in our progress were greatly appreciated. I highly recommend him to any members seeking a dedicated and effective personal trainer. If we return to Arizona, we will absolutely join Mountainside Fitness again and look forward to working with Caden for additional personal training sessions.

After 15 years of loyalty (roughly $18,000 in membership dues paid) I can confidently say…read moreMountainside Fitness has gone downhill. No more yearly buddy passes--so you can't even bring a friend to try the gym anymore. Then they refused to let me buy a day pass for my nephew because I'm not his father. Seriously? Zero flexibility and no common sense. And let's be real--it's overpriced for what you get. There are plenty of other gyms offering the same or better equipment and amenities without all these ridiculous restrictions. It's clear longtime members don't mean anything here anymore. Between the high cost, lack of benefits, and stupid policies, I'm done. Cancelling my membership and taking my business elsewhere. They try and make cancelling hard as well to detour you from doing so. Don't worry I'll comeback when whoever the "manager" is, is there to cancel. What a rip off.

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'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.
