I can’t say enough positive things about the Annandale team at Foundation Fitness! From my first interview with Patrick, I knew it was the perfect fit—their strategic approach combined with a family-oriented mindset really resonated with me. The trainers are incredibly knowledgeable, skilled, and accommodating. I work with Diego, whose kindness, encouragement, and thoughtful training style make every session enjoyable. Steven has also been supportive, helping me refine my overall fitness plan, while Michael offers invaluable nutritional advice. This team is genuine and dedicated! After five months, I've already seen fantastic results—shedding weight, building muscle, and reducing body fat. While I still have goals to reach, this initial phase has been a huge success. If I had to sum them up in one word, it would be: they genuinely care!

I am not a “gym person” … I’ve always been intimidated by them because I’ve never known what to do or how to do it. When I found Foundation Fitness, I immediately knew it was the perfect place for me! The atmosphere is upbeat and positive, the people are friendly and warm, and the facility is clean, well-equipped, and organized (plus, there’s plenty of parking!). Every time I walk in the door at the Annandale location, the trainers greet me by name and welcome me in. My trainer, Diego, is knowledgeable and motivating. Not only have I learned so much about strength training, but nutrition as well. Foundation Fitness takes a whole-body approach that makes you feel supported on all levels … AND IT WORKS! If you’re looking for a supportive place to start or continue your fitness journey, this is it.

I started at Foundation Fitness about seven months ago and have lost 20 pounds, losing fat while maintaining muscle. I feel stronger and happier overall, and I’ve been able to stay consistent in a way I never had before. The Annandale location has great vibes: welcoming, friendly, and really supportive.I’ve worked with Diego and he’s been awesome—super knowledgeable, motivating, and encouraging. Big shout-out to Steven too for getting me signed up, being super responsive with scheduling questions, and always bringing great energy. The other trainers are always friendly as well. And parking, no small deal in Northern VA, does not require entering a garage (it's a lot) and is super easy.Highly recommend if you are looking for a place to train.Get after it!

There are no gimmicks or tricks here, Foundation Fitness is just pure effective training and knowledge. These guys are phenomenal and have been tremendously effective for me over the last 6 months of training here. Diego, who I have done the majority of my sessions with, has been a valuable part of my success here. Through the whole team but especially his efforts, I have achieved significant measurable success in my overall fitness profile. I have gone from 26% to 20% BF, gained muscle, increased weights across all lifts, and most importantly learned and improved a variety of exercises and their forms.

Foundation Fitness has been instrumental in my fitness evolution. Everyone has been so carrying and supporting as I’ve started this journey about 9 months ago. The team has been so positive in every aspect of my training from Patrick making the first introduction, to Steven getting me started, and Diego, my trainer, who’s awesome at working with me to make my sessions personal and productive.While I sometimes have to travel, the team is flexible with my schedule and supportive in helping get all my sessions made up when it’s convenient for me. I highly recommend the staffing and personal trainers at Foundation Fitness!!
