Power Hour kills me!
Hey Lynne! Well you're not alone. Those low-ends in Power Hour kill me. I always have to stop before Cathe does and I use a lot less weight than her and a lot less weight than what I use with PS and her other strength training tapes. MIS was one of my first Cathe strength tapes and I haven't done it in awhile, but I agree it has a really tough leg section. Now that I think back I remember not being able to walk normally after doing that tape hehe! and the leg section is shorter than PS, S&H and LL so go figure. However I did LL for the first time last week and it took about 3 days for my legs to recover completely. I could finish the tape, but I had to stop for sips of water constantly and when I got to the plié squats my legs were quivering like crazy!!! My heart rate got as high as it used to get with Firm's Standing Legs. Maybe higher.
If I were to rate all the leg segments I would say that in terms of the toughness of the workouts I'd say Power Hour is the toughest, followed by LL, SL&A(floor), MIS, SL&A(standing), S&H:L&S. And in terms of recovery I would say that when I use LL my legs need a lot of time to recover so that would be the hardest one in terms of recovery followed by MIS, SL & A, Power Hour, and S&H:L&S. Well just my opinion. I think everybody is different.
