I think it took about 7-8 days to get my p90x package. I just finished my first week. This series is a roaring results monster.
Here is what I think would really enhance your experience of p90x.
Pull up bar with chair set up. I truly think you would cheat yourself out of some of the results of this program without it. Yes, you could do one-arm rows or pull overs, but pull ups have you feeling it EVERYWHERE. My entire arm area, lats, center back, lower back are WORKING and I can't even do one. The trick is to push yourself up lightly with the chair and resist the negative on your way down. OUCH!
Yoga mat. I bought a sticky mat and cannot believe I ever attempted yoga without one. It made all the difference in the world not to worry about my feet and hands slipping around.
Assorted (and heavy) dumbells (or bands) - I am surprised at how heavy I am able to lift with this series. My 20's and 15's are getting used more than ever.
Plyo mat - It's not a necessity, but boy does it help the impact stuff feel better.
Otherwise, water, towel and a hardcore I-can-do-it attitude. Good luck.
And...I have to said it again..."p90x type" training with Cathe's personality, her special touches and better music = RESULT CITY! I want a ticket to ride that rollercoaster. Can we start to beg her yet or is it too soon after her last round.
