It’s easy to get so wrapped up in another person’s success that you begin throwing out helpful pointers here and there too, in hopes they’ll fix whatever is keeping them from going even faster. This is where the problem begins, however, and it needs to be addressed before it gets any worse.
There is a fine line between shouting encouragements (“C’mon Jack! You can do it! Go go go!!”) and shouting unsolicited advice (“Push through your heels! Keep your elbows up! Drive with your hips!!). It’s one we cross readily and happily when watching sports on TV (“Don’t pass it to HIM you idiot, just go up the middle!), but it’s a line you should never, EVER cross at a CrossFit gym (this one or any other).
Ever hear the saying “too many cooks spoil the broth?” It goes for coaching too. In terms of improving their movements in the gym, people can generally process only one or two things at a time. It’s the coaches’ job to decide what those one are two things should be in that moment to help that person improve, and your cues will very likely disrupt what the coaches are trying to accomplish. The last thing a beginning athlete with a rounding back needs is advice on fine tuning their behind-the-neck snatch-grip push presses because you saw Coach Burgener use it to help Annie Thoridottir in a video on the CrossFit Journal.
However, the biggest reason you shouldn’t cross that line is simple: you are not the coach. And even if you are a coach somewhere, you are not the coach at this gym. Have respect for the people who ARE the coaches, and let them do the coaching. It’s their job, not yours. Unless the coach has specifically requested your help, you should keep your coaching cues to yourself (regardless of how badly you feel the athlete needs to hear them).
Cheering is highly encouraged in CrossFit, and everyone benefits from having people push them during the workouts. However, though your coaching cues are intended only to help, they may be doing far more harm than good.
