Debbie- Great workout today! That one sounded tough, I'm sure I'll have some problems with doing some of them too. P90X Legs and back is good but I wish there was more leg work or another leg workout to do in the series as well. I do love Cathe's Butts & Gutts and added just doing the floor work to the P90X Legs and Back. After reading your comments I'm thinking it would be good to alternate Legs and Back from P90X with Legs and Glutes of Cathe's workout and maybe add GS Back,Shoulders & Biceps- From chapters menu Just doing back only= 19 Minutes. I think that sounds like a good one to use with Legs and Glutes to change things up a bit from P90X Legs and Back. What do you think? I just don't feel that my back is getting worked enough. I don't have a chinup bar so I use resistance bands as shown. That's why I thought of doing GS BSB- but just the back only portion. Anyways, that's what I was thinking. So far, I like P90X I do miss Cathe though, she's got me spoiled. LOL!! I love reading your workout details, its always great to read and aspire to... I need to remember to post the workout details, but I always forget or am pressed for time and don't, I apologize.
