I, like most overweight people, have tried EVERY DIET imaginable with very little success. After years of battles and struggling, my weight reached my all-time high of 425 lbs in 2020 and I felt absolutely sick. I decided I had to do something. Much like everyone does, I cut out some foods and started light cardio. I started losing weight almost immediately! The first 50 lbs melted away pretty quickly, but then I plateaued. I was stuck. I started counting calories and adding more movement with no success. Luckily, I saw an ad on social media for Underground Fitness. That is where I met Gavino and Tripp. Both are excellent trainers. From day one, they pushed me and kept me accountable. Today, I weigh 235 lbs and I am still losing weight steadily. We have adjusted my goals and constantly adjust my strength training to push my limits and continue to make gains! My next goal is to break that 200 lb mark, and I feel confident that I will achieve that with Underground Fitness. Here, I’m not just a barcode that comes and goes. If I don’t show, Gavino is calling or texting me. He pushes when I need him to and doesn’t allow any excuses! That’s what has worked for me, and I have been able to stick with it for this long. I can’t say that about any other workout regiment or gym membership!

I was the 73 year old, sedentary, frail widow who decided it wasn’t too late to make a major change in my lifestyle. I spent months investigating gyms, yoga studios, different modes of exercise programs and finally found a trusted connection. Tucked in the southwest corner of 7th St & Mountain View is a petite building that houses Underground Fitness. Yes, good things come in small packages and even better are the big results from their expertise. My trainer, Roxie, does more than just instruct, she demonstrates and explains each exercise. I feel safe as she optimistically cheerleads me through activities using a wide variety of equipment. Even my friends have noticed my improved endurance, stamina, and toning. Underground Fitness is my get-fit., feels like home, personal gym. I’m optimistic about reaching my goals and setting new ones.
