Sports-performance training, also called sport-specific training, is a fun and exciting approach to expand your client base and increase your revenue. If you choose to do this type of training, you will most likely be working with recreational, school-age, or college-level athletes. The goal is to help them become better athletes through intense physical training. The beauty of sports-performance training is that it can be performed anywhere, and with very little equipment. The programs you run and settings you work in will vary depending upon the age and ability of your clientele.
