A gymnast must be flexible, and have near-perfect balance, grace, strength, and endurance.
Women's gymnastics practices on 4 different apparatus, each with it's own challenges: uneaven bars, balance beam, vault, floor exercise
In artistic gymnastics there are 8 different apparatus - Vault, Uneven Bars, Beam and Floor for the women and Floor, Pommel Horse, Rings, Vault, Parallel Bars and High Bar for the men.
Exercises include multiple somersaults/somersaults with twists, jumps and dance elements. Requires great power, flexibility, determination and will power, and a high level of fitness.
Rhythmic Gymnastics, or RSG for short, in a nutshell, involves women - men don't do RSG - who are too tall for AG bending their bodies into grotesque shapes while chucking either a ball, club, rope or ribbon in the air. Requires great flexibility. Judging at international competitions is often biased and fixed, and the very top gymnasts always seem to get temporarily banned for drug abuse...

"No... wait... you move this way. No, no, not... yeah, that way. Now grab that shirt. Or the shorts... whatever you can reach. Yeah, that's fine, that'll work." *scampers off to bathroom*
Friend 2: I know. Isn't ballet just so much prettier and better?
