Have always had a tough time with a technique.

I have always had a very tough time alternate picking going from different strings. A good example of what would be very challenging for me is the first part dez goes over in this video. https://www.youtube.com/watch?v=-0AGqQiOmug or this https://www.youtube.com/watch?v=gjNAV42YhGY Are there any practice routines to get over this?

There's no exercice to get over this. You have to adopt the proper picking technique(s). Downstrokes must dive under the string so the upstrokes do the opposite and allow you to skip strings before the next downstroke. You can do that by modifying your attack angle or using a complementary motion that will help skipping the strings every upstrokes. Depends on your current technique.

No time to watch the vids right now but if you're describing what I think you are, best thing to do is watch Paul Gilbert's Intense Rock vids and do the first few exercises from that over and over.

Also, Redstone is right regarding hand position and angle, that's everything for getting alternate picking down properly.
