Melissa Van Sant
Coach
CrossFit Level 2 Coach I’ve been coaching for almost 10 years, and in that time, coaching has taught me just as much as it’s taught my athletes. I’ve learned how to truly connect with people, meet them where they are, and help them grow stronger — both physically and mentally — while working toward goals they once thought were out of reach.
My favorite moment as a coach is when an athlete has that realization: “Oh… I can actually do this.” Watching someone discover just how strong their body really is never gets old. These days, I’m a full-time student and part-time coach, usually focused on surviving my own workouts while Mark stands behind me, rolling his eyes and reminding me to “try harder” and “move faster.”
That said… heavy lifting is my love language. If it’s heavy, I’m in. Snatches. Cleans. Back squats. Front squats. All of it. My passion for coaching comes from helping people realize what they’re capable of. Coaching isn’t just about workouts — it’s about confidence, consistency, and proving to yourself that you can do hard things. Happydaysahead_6
