HIIT
HIIT at CrossFit Fairfax combines short, intense work intervals with real coaching, so you get a genuinely challenging conditioning session without the workout dragging on — a great fit if you want serious intensity on a tighter schedule.
Every session is coached from warm-up to cool-down, with movements and pacing scaled to your level — you're pushed, not overwhelmed.
Your First Session Is On Us
Book a free 1-on-1 intro with a coach. We will assess your goals, walk you through the gym, and build a plan that fits your life.
What to Expect?
Expect a quick, focused warm-up followed by rounds of high-intensity work paired with short recovery periods — the exact format varies by class, but the intensity stays real every time.
Coaches cue form and pacing throughout, so you're working hard safely, not just working hard.
