I tried GS Legs timesaver premix (33 mins) today. My routine today is about 30 min legs, 30 minute upper body (I did timesaver GSBSB) and 30 minutes aerobic exercise (haven't decided what to do yet). Anyway, I hate to add to the negative comments, as I definitely think that Cathe is the best instructor out there, but I was disappointed in the timesaver GSL. I did not really feel worked out, and I used heavier weights than the group did on every exercise. I don't think the band for legs is nearly as effective as weights. When I do the Pyramid Up for Lower body (also about 30 mintues), I really do feel worked out. So, at this point, I don't think I'll use the GSL timesavers very much. In contrast to GSL, the timesaver for GSBSB was very, very good. I definitely will feel my shoulders tomorrow. The band was great for these body parts, especially the smaller muscles groups of the shoulders and biceps.
While I am at it, I'll chime in about the music. There is a clear difference between the HC series and the others (I have almost all of them). For a company that prides itself on customer friendly service, I don't think SNM has handled this issue very well. I would even be satisfied if they just said "we goofed. sorry you guys, we will deifinitely make the music options and sound quality a priority next time. please stick with us." That sort of acknowledgment would not cost them a thing! Instead we are getting loads of excuses that frankly are ridiculous.
