Lighter squats, deadlifts, presses, and bench presses. As light as it takes for you to be able to do them right now, and then progressively heavier bit by bit as the recovery of the strain allows, so it heals within the context that it'll be used to lift heavy again. If you want to throw in some extra isolation work that doesn't exacerbate the existing issue, while your main lifts are artificially light due to the strain, I don't see a problem with that.
