Cheryl:
don't be intimidated by Leaner Legs. I bought the CTX series last Spetember and stayed well away from LL because everyone here said how much of a monster it is, and I've worked instead with PS legs and PLB for legs.
So last night I took the plunge and did CTX All Step and LL right after, using, for the first time out, the same weight loads Cathe uses, and I really and truly do not believe that it is any harder than PS legs or even Power Hour for that maatter. The low ends on PH kill me. If you can do PS legs, you can do LL. Preview it and convince yourself of this fact. The single leg lunges are particularly efffective. You can do this, "yes you can!"
Go for it!
