I practice aerobic exercise. Aerobics can be divided into mass, competitive and lesbian, and then there are seven basic steps, namely, stepping (but we usually do bouncing), opening and closing, sprinting, sucking legs, kicking, bouncing and kicking. There are many terms. For example, if the scores are grouped, there are first-class group, adult group, second-class group ~ ~ ~ complete sets, men's singles, women's singles, mixed doubles, three people, six people ~ difficulty, ABCD, four types of difficulty, A is dynamic strength, B is static strength (support and level), C is jumping, and D is. I can't tell you bit by bit here. If you still want to know, you can go to the aerobics competition network, which has an introduction, and you can contact me if you need it ~
