If you're big into sports, you can make a little money off your athleticism by coaching. There are numerous opportunities to coach throughout the year, because you can work in one or multiple sports if you're qualified. If you choose to focus on just one team sport, you can search public and private school systems for positions. School job requirements and obligations will vary by county and state, of course, and may entail more than you're able to commit. But club sports, like off-season volleyball and soccer, hire coaches as well. If you're not up to speed on the club sports in your area, check with your local YMCA, which can point you in the right direction. A club sports coaching job will still require much of your free time, but it generally pays well. Pay can vary, but Virginia's Volleyball 4 Youth pays its coaches an average of $100 per player with a team cap of $5,000 per season [source: VB4Y]. Your knowledge of and experience coaching volleyball would obviously determine your exact salary. If you can't decide on a sport, you may want to offer personal training services. Training doesn't have to take place at the gym. You could work on a one-on-one basis teaching soccer or volleyball skills, or as a running or swimming coach. Whatever you choose, charge competitive rates for your services and set a schedule for the season or training period.
