Mortac, the only video I have is this. For a strong individual, if you don’t have a leg press available, you could use a metallic chair and strap both ankles and the hips.
I agree with Charlie. Most of the research on EMS in North America has been done with medical therapy in mind. Some scientists (not all) used: current intensity that was too low; pulse widths that were too short; off time between contractions that was too short, causing muscle fibers to fatigue too soon. In other words, they had a background in EMS for physiotherapy, but not in training. No wonder they didn’t get results, or they couldn’t reproduce results shown in other studies. That said, there are examples of good studies too. Most of them are done in Europe by scientists knowledgeable about training. Besides the study mentioned by KBM, see the following (with links to the abstract):[ul]

This is a good review of the field, although what is said on recovery is superseded by more recent studies showing results on recovery too.
