EXCELLENTTrustindex verifies that the original source of the review is Google. Having never been to a circuit class before I felt really nervous coming to my first total body workout class here. But Bryan did a great job to make me feel really welcomed and comfortable taking this first class. Now, I love starting my Saturdays with a total body class, it challenges me each week in different ways and I love that!Trustindex verifies that the original source of the review is Google. When I lived in San Diego I LOVED this gym. The classes were always different and challenging. I workout a decent amount and get bored with most gyms I go to, however this was the one gym I never got bored with. The people (trainers and other class members) are awesome. The music is great. I moved back to New England but whenever I travel to San Diego I make sure to buy day passes to this gym so I can experience those great workouts again. Highly recommend!Trustindex verifies that the original source of the review is Google. Fantastic gym!! Great people to workout with. Music is great and the workouts give a good sweat and motivation. Thanks VersatileTrustindex verifies that the original source of the review is Google. I love this gym. I don’t come nearly as often as I want to (or I should), but when I do it’s always a win. The training is fun, the trainers are great and the facility has parking!! Added bonus: Bubba the dog pets is therapy.Trustindex verifies that the original source of the review is Google. Bryan, Edgar and team are fantastic trainers! They motivate and push me during my workouts, and have created an excellent workout environment/ community.Trustindex verifies that the original source of the review is Google. Hidden gem in PB - all three trainers are awesome (Bryan, Edgar, and Sean) and mix the workouts up everyday. Coolest part of the gym is the people. My GF and I just moved to the area and they’ve all been nothing but warm and friendly! It feels like a welcoming community of really motivated folks.Trustindex verifies that the original source of the review is Google. Great gym...all the trainers and owner are very knowledgeable and create very good workouts on a daily basis..no 2 classes are the same!Trustindex verifies that the original source of the review is Google. I have been exercising and training since the late 90s (not to age myself), and I've worked with 3 personal trainers, tried every new fitness program from lifting, cardio, circuit training, tabata, CrossFit, HIIT workouts, yoga, cardio, and sports. I've tried all the new circuit classes from Revel Fit, Renegade, OTF, F45, and I guarantee that no one will program or kick your a$$ like Bryan at Versatile Fitness! This is a no-frills, old boxing gym vibe (think OG Rocky) where you come to WORK! Bryan's programming, exercise acumen, and super sets will challenge you, but also be some of the most effective and productive workouts. He has almost every piece of equipment I've seen in a gym from rowers, ropes, barbells, curl bars, pulley systems, sleds, water weights, benches, kettlebells, free weights, Terra core, TRX, bands, discs, and the list goes on. I have attended about 10 classes and I have yet to repeat a workout. It's insane the quality of training and programming you would get through this gym for the price. Anywhere else, it would cost thousands for this level of programming, so anyone who attends these classes is getting a steal of a deal for this type of workout! Classes are 45min, with several stations per class. Each day has a target focus such as pull, push, leg, abs, and/or cardio, depending on the day. The target is there, but you are always getting a decent total body workout. Each station has 2-3 exercises that you do 2 sets per station. You have around 3 people per station, and then you rotate. Bryan goes around to demo each exercise as you move stations, and also has the workouts written on a whiteboard at the front of the room. Bryan will also provide quick corrections, as needed. Please note, in large group class settings, rarely will get you get alot of correction or instruction. It's not feasible to have that much personalized focus in these types of classes. Each class starts with a short warm-up, and a quick cooldown at the end. I have only taken class with Bryan, as he is the staple of this gym. He also has an extensive background with over 20yr of experience and he also offers some nutrition and personalized coaching programs for fat shredding and other fitness goals. This gym is a hidden gem and morning classes are usually full. I am literally perplexed how the afternoon classes are not exploding with members because I have yet to see anyone have the stellar exercise programming and versatility that Versatile Fitness provides. I've seen so many different trainers and attended many gyms, and Bryan's programming is the most innovative and BRUTAL (in the best way), that I've experienced. If you're looking for a serious SWEAT, a great community, and incredible workouts, VF is the spot!Trustindex verifies that the original source of the review is Google. HIGHLY RECOMMEND!!! One of the hardest workout but if you're a beginner they make you feel comfortable on what works for you best and be motivated to get to the next level!Trustindex verifies that the original source of the review is Google. I discovered Versatile Fitness on Class Pass and am now a regular when I want a workout that will really challenge me. I like that it has parking too! Each class is different which is super fun
