I have always been pretty active, being a former athlete, but when my man was asked to be in his cousin’s wedding, my GroundWorX journey began. I knew I needed something that could accommodate my previous knee injury but also be aggressive enough to yield results in a restricted timeframe. I HATE the gym! Even as an athlete, the gym was a space of distraction and harassment. However, GroundWorX provided a regimen for me that is conducive to my home space, and I haven’t looked back. Initially, I dropped 10 lbs. quickly with the exercise regimens and diet adjustments, but as my regimens have progressed, my body has responded and I am firmer and more muscular. It may be vain, but I just wanted to look and feel good in my body. The biggest challenge was myself. There were several occasions I wanted to give up, wanted to cry, and wanted to use my cycle as an excuse, but I owed it to myself to be my best self and found the strength to power through. I had to be consistent and accountable as hell. The coaching is great! Mental and physical check-ins on the regimens. The approach to a balanced diet, as well as work-life balance. Having someone who understands that whole health is just as important as physical health has been very refreshing. I am still on this journey called life, but I will say since participating in GroundWorX, it has enhanced my quality of life and ability to show up, participate, and enjoy the journey and where it takes me.




Having David as my personal trainer is one of the best decisions I’ve made since meeting him. The biggest thing I’ve learned from him is to always have a plan. Know which muscle you want to train, the movements you’re going to do, and maintain proper form throughout your workout. That way, you’re not spending hours in the gym, which is one of the reasons he’s so efficient. You shouldn’t be in the gym for longer than an hour. Time is valuable, so get in, train hard, and get out! His attention to detail is second to none. When he makes even the smallest adjustment to your form, it makes a big difference. He makes training both challenging and fun. All you have to do is follow his instructions, and you will see results!


I’ve been training with David since the summer of 2024. When I came to him, I was still healing from a back injury I suffered in 2020 that continued to give me problems for years. Through training with him, I’ve been able to regain the flexibility and mobility I lost, and honestly, I’m doing things now that I wasn’t sure I’d ever be able to do again. One of the things I appreciate most about David is how attentive he is to his clients. He pays attention—not just to how you’re performing an exercise, but to how your body is responding, what you’re struggling with, and when it’s time to push you or pull things back. Because he takes the time to really know the people he works with, he’s able to meet you where you are while still helping you move toward your goals. Working with David hasn’t just been about the physical results. Through consistent training, I’ve rebuilt my confidence both athletically and personally. If you’re looking for a trainer who’s invested in helping you make a real lifestyle change instead of chasing a quick fix, he’s the person you want to work with.
