When in normal status use a "Hyper." This will let your limit meter go up faster, so you can use your old techniques more. The reason for this is that one way to get your limit breaks gained is to use your old techniques.

WARNING: When you use the "Hyper," your status changes to "Fury," which will lessen your hit rate.

Another way to gain your limit breaks is to defeat large groups of enemies. Try this: When leaving the Nibel Mountains and heading for Rocket Town, you should see a group of forests when you leave the mountains. Try engaging combat there, because sometimes you fight large groups of enemies there. Such as a group of six "Battery Caps," or sometimes five "Battery Caps" and one "Valron." This might help in getting your limit techniques also.
