    Nicole and Haley are amazing fitness trainers! They have created a workout environment that is exciting and motivating!! I am thrilled to be able to workout in a friendly, loving and challenging place.

    C4F has created what feels like a fit family. They make working out and eating healthy FUN. I love all of the workouts and the fast pace of each session. Time flies by having a blast with the up beat music and fellow members that have become friends. Highly recommend C4F if you're looking for a new spin on staying fit.

    #28daysummershredchallenge So this month was the #28daysummershredchallenge! I decided to join the challenge because I needed that extra boost, accountability and wanted to get back on track with my mental health and weight. With the personalized meal plan, bonus workout day, accountability and #Prestigelabs supplements I have lost 8.6 pounds in just under 28 days! With that I have gained muscle and feel like I have more energy than I know what to do with! Coaches Tato, Jillian, Clyde, Whitney and Haley have been so supportive through out this challenge and having them join the boot camp to workout with everyone is EVERYTHING! Thank you Cali4Fitness for all your support, dedication and hard work. I am so blessed to have such great support

    The owner and some pretty awesome physical therapists that eliminate pain and prevent injury!

    Cali 4 fitness is my fav group fitness gym in SD. Not only are the workouts incredible, but the staff is super knowledgeable and can help modify exercises if the intensity is too high. They also have injury specialists that come and do workshops that helped me eliminate pain and stay injury free! Lastly, the community bon fires, BBQs at the owners house, and hikes are a huge bonus!

    Cali 4 fitness is a top of the line gym, and is 100% worth investing your time and money in! The workouts are intentional, fun, and challenging. If you can dedicate 45 minutes of your day to working out at Cali 4 you will see results and fill your body become healthier. Nutrition is probably one of the hardest parts of anyone's fitness journey, but Jillian is super involved in educating you on ways to change your diet and she is an awesome cheerleader, which really helps keep you motivated. The gym is super clean, workouts always start on time, and if you have any issues they are handled quickly and efficiently. Jillian and Tato just know what they are doing! They also find ways to make the gym a community with holiday workouts or special gym outings, which I think is super special about Cali 4 Fitness. You are joining a fit fam rather then a gym. Thank you Cali 4 fitness for helping me on my fitness journey. You guys rock

    Living in Hillcrest has so many components that make it a terrific place to live, and one of the…read moreforemost among them is having Prime Fitness just around the corner from my house. Conveniently located on First Street and accessible 24 hours, the gym is clean and well-maintained. Occupying the entire ground floor of a building, it has a feeling of spaciousness about it. Doors that open to the small patio area, along with ceiling fans, enable good air circulation throughout the space. Fellow gym-goers are friendly and always willing to engage when you approach them about routines or exercises. No attitude at this place whatsoever. People are genuinely happy to share their successes and reflections on their own self-journeys to fitness, which makes the gym feel like not only a place the place where you can go to work out, but also a place where you can continually learn from other gym enthusiasts about ways to improve your own focus on physical improvement. A sense of a community among people with a common interest in health and fitness, and a willingness to share it, are two of of the most unique and notable characteristics of this gym. The owner, Keith Deidrich, pays meticulous attention to the gym's layout and functionality, resulting in a nice rotation of machines and weights throughout the space. It's exciting to come in to find a new machine, such as the very impressive cable crossover set up, complete with high bars for dead-hangs and pull-ups, or a one-of-a-kind lat pull-over machine that requires the force of your elbows, placed on pads and pushing down, to accomplish the exercise. It's like a squat machine for the upper body. In addition to the machines and freeweights, the gym has add-on weight blocks in gradations of two-and-a-half pounds that are custom-made to be inserted on top of the machine pulley racks to increase the resistance in smaller increments when the built-in 10- or 15-pound increases are too much of a step-up. Being able to use these blocks has enabled me to slowly increase the amount I'm lifting without making a jump up to a higher weight that is just too heavy. And there are plenty of cardio machines as well. In short, this neighborhood-centered gym with its relaxed vibe, excellent equipment, and friendly and respectful members makes working out a highlight of my daily schedule.

    I first came across Renegade on ClassPass and was so impressed with the experience that I decided…read moreto become a member. This gym offers a wide variety of bootcamp like classes with fantastic energy and some truly talented coaches. While there are a few who are overly egotistical and could use a come back to earth reality check and a touch more humility, the majority of the coaching staff is excellent. Two standouts are Gabrielle Y. and Christian Q., who make working out an absolute pleasure. Gabrielle's welcoming demeanor and contagious positivity create a great atmosphere, and Christian's coaching style is equally motivating and supportive. The classes themselves are high-energy, challenging, and adaptable to different fitness levels. What I love most is that each coach brings their unique style and energy to the table. Once you find the coach who resonate with you, it's easy to stick with them and stay consistent. The variety keeps things interesting, and you'll never get bored while working toward your fitness goals. One of the challenges, however, is parking. Since Lazy Acres put up signs claiming what feels like half the lot, finding a spot can be a headache. I've learned not to arrive too early because spots typically free up only once the previous class ends. While it can be frustrating to circle the lot, a little patience and timing go a long way. It's something to keep in mind when planning your visits. The gym itself could benefit from more regular cleaning and maintenance. A deep cleaning is definitely overdue, as dust, hair, and even cobwebs can be seen in corners. Some benches are rusty and could use replacing. While these issues don't take away from the quality of the workouts, they do detract from the overall experience. Many other gyms in the area have weekly professional cleaning services, which could be a great addition here to help maintain a fresher, more polished environment. Despite these minor drawbacks, Renegade remains a fantastic place to work out. The membership is reasonably priced, although ClassPass is still more affordable and offers lower price penalties for late cancellations. Overall, the quality of the classes and the dedication of standout coaches like Gabrielle and Christian make this gym worth checking out. If you're looking for a challenging yet welcoming environment to achieve your fitness goals, Renegade is a solid choice--just plan ahead for parking and connect with the coaches whose energy aligns with yours!

I hope that one day I might join in on the fun there and go a great workout too. Thank you for listening and being so respectful. Empathy goes a long way!

The gym focuses in on efficient and proper forms/techniques on all their workouts. The main concept is that all classes are split into 2 types, the "tuff" and "rig". As you guessed it's basically cardio or lift. You can decide what you like to do based on your body and your goals. I've personally have not tried other "similar" type of gyms but from the feedbacks of others I've talked to, this gym's program and setup is one of the most effective. From the owner Rory to the trainers Brooke/Loccy, everyone greets you with a smile and only sends positive support. No judgement on the amount of weight you use nor the amount of reps you can do. As long as you give it your all! It's a pretty even 50/50 split with men and women. Don't be afraid to come check it out! I highly recommend.

I began in July and Lindsey and the community in this gym have truly changed my life and pushed me to be more confident in my skin, believe in myself more and have taught me that I am so much stronger and capable than I think I am. She creates long lasting healthy habits that are realistic. She truly cares so much about the people that enter her gym and you become apart of the Underground Fitness family. I'm so happy I found this community. I couldn't recommend a better gym to start your personal training journey!!!
