Hi KatC213,
I did not calculate 1RM for ICE as I don't think Cathe specifies she used it for ICE. The only DVDs that I'm aware use the 1RM to choose your weight selections are STS, STS Total Body, and Xtrain, and maybe RWH (altho I don't think RWH are in the Workout Manager). However, you can still use the progressive overload concept to increase strength in any series or rotation ... ("Progressive overload is when you gradually increase the weight, frequency, or number of repetitions in your strength training routine. This challenges your body and allows your musculoskeletal system to get stronger"). Having said that, after doing STS and/or Xtrain, I usually adjust my weights somewhat for other series because of the gains I made doing STS/Xtrain - keeping in mind the rep count/speed in the particular workout. Often when beginning a new-to-me workout, I'll select my weight used based on Cathe's selected weight and knowing from STS how my weight used for a particular exercise compares to Cathe's - Cathe's stronger than I am in many shoulder, chest, bi's/tri's exercises, but I can usually match her or go heavier for legs, back and some shoulder exercises. Then I adjust accordingly to make the workout a challenge for me. Thus the importance of keeping track of the weights you use in each workout - plus it's motivating to see on paper how your weights increase over time. HTH, Deb
