So, today was my first session as an unofficial practitioner of Starting Strength. Conveniently enough, I’m roughly as strong as Rippetoe’s hypothetical student, so the baseline figures he uses as illustrative examples actually work pretty well for me. I hope I’m able to see the sorts of gains in terms of strength that he suggests that relative novice lifters will enjoy for a while, though if I’m a little slower — due to age, and the fact that I’ve been training for the best part of a year — I won’t be horribly disappointed.
Any progress is better than none.
