How do I maintain focus with a manual lens while filming?

It really depends. If you're filming hand held, or on a tripod, then you just need a little practice. If you're filming on a steadicam or a stabilizer, you may need someone else to rack focus for you. One thing that really helps is to use a smaller aperture, and therefore a deeper depth of field. This makes nailing focus a lot easier.
 
Either set & forget (focus to infinity) or set to a focal length and try to stay that same distance the entire time. You can also try to have an aperture that isn't very wide, so higher like f 8 or f11 ish.
 
Most of the time, you will be able to set your focus on a shot and you wont have to change it, unless you're filming a long line on a tripod. For follow cams, just set your fstop to 11 or 16, focus to infinity (or just before infinity) and dont get closer than 3-4ft of your subject while following and youre good to go.

wait so what if you're filming a more skateboard esque shot. like where you get closer to the feature at the end? (not sure what its actually called)

if you want the rail in focus just pull focus to the rail at the end
