Usually activities done in high school are too "old" for W/A unless it's something extraordinary like a STS/ISEF Grand Prize, Presidential Scholar, or Eagle Scout award. I think you can put it all under one header where you describe or focus on your wrestling coaching.
I asked because I wanted to know about service orientation activities, such as food distribution, shelter volunteering, job/tax preparation, transportation services, or housing rehabilitation. If you have zero hours in this category, many schools will deny your application regardless of anything else you have in your application.
