Fishing rods come in various actions, which refer to how much the rod will bend when pressure is applied to the tip. The main actions are:

1. Fast Action: These rods bend mostly at the tip and are great for long-distance casting, quick hook sets, and fishing in cover.

2. Medium Action: These rods bend in the top half of the rod, providing a balance between sensitivity and power. They are versatile and suitable for many fishing techniques.

3. Slow Action: These rods bend throughout their length, offering more flexibility and shock absorption. They are ideal for fighting small or medium-sized fish and for fishing with light lines.

It's essential to choose the right action based on the type of fishing you'll be doing. For example, if you are fishing for bass in heavy cover, a fast action rod will help you set the hook quickly and control the fish. On the other hand, if you are trout fishing in streams, a medium or slow action rod may be more suitable for playing the fish delicately.
