If you are working in an open wall space, I would use NM-B (sheathed electrical cable) instead of EMT (conduit) and drill circular holes through the heart of the studs instead of notching for EMT. 3/4 inch circular holes in the center do not weaken the stud nearly as much as notching. (Circles distribute force more evenly than squares or rectangles). Also, sheathed electrical cable is INCREDIBLY easier to use than threading THHN wire through conduit. You can just thread the sheathed electrical cable wire through the center holes in the studs instead of doing all the notching, threading, securing, etc. Ten minutes of work instead of hours.
If your local code requires EMT for all wiring (like in Chicago), then there are metal plates you should nail on tthe edge of the notch that not only protect the EMT from inadvertant nails/screws, but also reinforce the stud a bit. The ones that reinforce wrap around the sides of the stud, as opposed to just tacking onto the face of the stud.
You could also put some sort of insulation between the conduit and the protective plate so that a ground fault does not convey through the protective plate, thereby shocking anyone who inadvertantly nails through it.
