my u joints always break! S**T

Stock height or lifted? When they break, is it the cross or the cap that comes out? Is the yoke on the axle in good shape? The tabs on the edges (if so equiped) still there? Getting any axle wrap? When they break, is it under normal driving conditions?
Little more info would help.

Are the U-joints the greasable kind and if so did you grease them after they were installed and before use?
Which U-joint is the one that breaks, rear shaft front joint or rear shaft rear joint, front shaft?

Yes that is one way to kill u-joints, but said they were breaking under "normal driving conditions". but wow, that vid is rediculous.
There are a lot of ways U-joints will fail. Could be the wrong joint, could be the wrong strap style, could be grossly overtightened crushing the caps...there are a lot of variables other than angle, abuse and axle wrap.
