How do you keep combat descriptions interesting?

Specifically as a player, and especially as a martial class, as a player, how do you keep your attacks interesting? I feel like 75% of the things I do in combat can be summed up by saying "stabby stab" because the only thing I can do is a physical attack. "It's your turn," the DM says, "what do you do?"

"The only thing I'm capable of doing and the same thing I've done every combat. I stab the enemy"

Thoughts?
