I was planning to do the 1RM over the weekend, but I ended up guesstimating what weight I could use for 10 reps for each exercise on disk 1 and entered that into the 1RM calculator so I could get the workout card. I did Disk 1 on Saturday, and some of the target weights were right on, but others I had to adjust. I just took notes on each of the exercises, how many reps I actually did, was the weight too heavy, too light, etc. so I just plan to take those notes into consideration for the next workout. I guess I was too anxious to get started.....and doing all of the 1RMs for real seemed like a workout in itself.
