Jacob was the first trainer to truly stop and focus on the basics. You’d be surprised to learn that, after so many years, I didn’t know how to properly engage my core. He is technical, educational, and encouraging, and he adapts to your individual needs. While we didn’t delve into nutrition as much as I would have liked, his guidance on weight training, form, and technique was excellent.

Jacob is a great trainer and an even better person! I visited his gym for a consultation to discuss my fitness goals and he created a customized training plan just for me. He genuinely cares about ensuring that I achieve my objectives and I highly recommend working with him.

I love my workouts with Jacob. He has a very calming energy which I really appreciate. Jacob is super knowledgeable about the body and really helps point out exactly which muscles should be working during each exercise. As someone who is new to weight lifting it can be intimidating, but Jacob really breaks it down step by step and does demos to make it clear. I will definitely keep going to him!

I worked with Jacob for two years consistently and always looked forward to sessions with him. In that time I had huge progress! He is very good at listening and taking feedback from a session and immediately introducing it into the next. He also takes a very scientific approach to training and always has a reason for introducing some change or just a simple exercise cue.

My biggest issue was balance and symmetry which is the hardest thing to correct imo. Lots of trainers out there that could push me to my limit and make muscle gains but Jacob took a linear, progressive, educated approach to meeting my goals like few could. Highly recommend him to anyone!

Hands down, the best personal trainer ever! Jacob not only creates new and challenging workouts each session, he also tailors workouts around my past injuries which has helped me stay active and motivated. He’s extremely knowledgeable in what he does and helps you hold yourself accountable. Since working with him, I have made healthier lifestyle choices that I wouldn’t have been able to do on my own. For anyone considering working with a personal trainer, I couldn’t recommend Jacob more.

I have been training for 5 months and am thrilled with my improved strength and overall toning. I have an injury that Jacob has addressed with his expertise and have steadily improved. Jacob positively motivates you and keeps you challenged with new workouts. I didn’t like to workout in the past, but now I look forward to my workouts!

I always look forward to my workouts with Jacob! He is always in good spirits and has my workout well planned out and that plan in always well executed. He pays close attention and has endless knowledge to help
Me advance and grow stronger. Such a good investment! I highly recommend Jacob as an exceedingly talented trainer. He “gets it”!

Been training 1:1 with Jacob at 1&23 Fitness for about a year and a half now. Hands down one of the best investments I’ve made in myself. I’ve had some awesome personal trainers before, and Jacob is at the top. His experience, positivity, and sessions focused on my personal fitness goals have made a huge difference in both my strength and overall body condition. Besides strength training in the gym, Jacob has also been able to guide me with my eating plans as well. Both in bulking to build muscle and in cutting to trim down as well. I would highly recommend Jacob, and to top it off - he’s conveniently located right off i-25 and Speer Blvd in Lo-Hi. 💪🏼
