The exact opposite of what the fellow in the video did. An old gardener, a friend of mine, taught me to remove any branches that will not produce and are not required for support. I love it, but it does take a lot to keep the plant fed and producing. I did get 250 tomatoes off an Early Girl a few years back with this system.
That's not an exaggeration, either. I made myself pick even dozens each time I picked, and I made a hatch mark on the fridge. There were 20 hatch marks the night of the big freeze. (I ran out and snagged a bunch of smaller green ones to make it an even 250
)
I think I have a photo of that tomato bed. Let me check. Yes. I hope this link still works:

Naturally, they're between prunings in this shot, so you can't see the tomatoes. The ones out front are yellow pears. I didn't count my yield from those; it was well into the hundreds on each plant, 5-gallon pail after 5-gallon pail. I will never grow yellow pears again. I got very tired of picking them.
Admittedly, I had planted the Early Girl earlier than I did this year's Lemon Boys, setting her out in mid-April. She was in the bed right behind my house, right in front of the dryer vent. One night, after covering these tomatoes, I ran the dryer empty during the worst of the temperature drop. I think that may have saved the lot!
Because the Lemon Boys were just pruned, I'll get photos of them once the sun hits them. I checked, and that's an hour, at least, away. The sun is rising later and later, BTW, in case no one else noticed
