Sparring happens in exactly two places here: Saturday at 11:00 AM and Friday Clinch Night. Both require you to ask a coach to add you. That rule surprises people, so it is worth explaining.
Most gyms let anyone jump into sparring on day one, and most gyms have a story about the day that went wrong. We would rather have a short awkward conversation than a bad round. When you ask, the coach who has watched you train will tell you honestly whether you are ready, and if you are not, exactly what to fix first.
Readiness is not about winning. It is about control: can you move without crossing your feet, keep your guard up when you are tired, and pull a punch when your partner is open? Those are fundamentals-class skills, which is why most people spar within their first two or three months without rushing it.
Saturday sparring is capped and supervised, with headgear required and coaches pairing people by size and experience. Friday is clinch only, which is slower, closer, and the best bridge between drills and open rounds. Ask any coach after any class. The answer is usually yes, and when it is not yet, it comes with a plan.
