Q: What do you call a round kick with no pivot?

A: it is a Front Kick

Though some schools, may most schools teach their round and side and hook kicks without a full pivot I encourage my students to perform a full pivot when ever practicing these kicks. Why you might ask? Because it is always possible to perform less then you practice with ease when necessary but to perform more is a rare ability if not an impossibility. A full pivot enables maximum power and range for each of these kicks.
