I have been doing 7-7 for a bit and am finding it works really well for me. There are several things going on that steered me toward this:
-- I
adore Shovelglove! It really invigorates me! It gets me going in the morning, even the 7-minute version! And now I have found that the 7 minutes in the evening seems to keep my energy level up over the course of the evening, and makes a nice boundary between daytime and evening activities as well. (On nights when I won't be getting home until late, I plan on doing the full 14 minutes in the morning).
-- Not to worry, Reinhard: because I like it so much, I don't have a problem with starting a second time, especially for only 7 minutes.
-- I also walk for 40-45 minutes 6 days a week, and do a 30-minute weights routine 3 times a week, so I'm not looking to Shovelglove as my only source of cardio or strength training.
-- I recently added Z-Health's neural warm-up to my program. It takes about 10 minutes right when I get up. I am also enjoying that routine, but that 10 minutes, plus the 14 minutes of shugging, put me just beyond the degree of complexity I want in my morning. (There are
lots of other things that go on besides exercise!) 7-7 solves that, plus there is the bonus of added evening energy from the second session.

One advantage worth considering is that, because you'd be rested, you could maintain a much higher intensity level for a second 7-minute session as opposed to what you could do during the second 7 minutes of a longer routine.
Phayze -- Thank you for that encouragement. I think I've also heard of those studies, but I didn't think of them in this context. And, although I wasn't really thinking about of it, you're right about the intensity of the evening set: it is definitely more intense that the last 7 of 14! Your thoughts are much appreciated! (BTW, I hope you are feeling better ...)
Having said all that, I do recognize that there might be some pitfalls down the road in terms of getting to that second set, so I wouldn't suggest that anyone "try this at home" without really thinking through the commitment, and I'll be on my toes to insure that this doesn't mess up my Shovelglove mission.
