I am absolutely thrilled with STS - the variety, the hard work, the results... and can see why the 1RM is so important, but I'm wondering how everyone is doing maintaining their calculated weight by the end of a workout. In other words, based on my 1RM calculation I should have been able to do a wide grip barbell curl with 30 lbs; however, when that exercise came at the end of Disc 1 when my biceps were fried, I could only manage 20 pounds. Still a great workout, but how does STS/1RM take into account the rest of the test vs. the muscle exhaustion of doing an exercise when it is placed near the end of a workout? I can handle the first half of the work outs well, but by the time I'm about 2/3rds done, I'm finding I have to lessen the weights because Cathe has kicked my butt. Thoughts?
