full-out

At maximum effort

Full-out means with maximum effort or intensity, holding nothing back: a full-out sprint to the finish, full-out war.

The term emphasizes totality—no restraint, no reserve.

In dance and theater, a full-out rehearsal runs at performance level rather than marking through movements.
