I seriously disagree with this. 60 minutes is more than sufficient if you aren't screwing around. I also think it's baffling that people are still recommending Starting Strength when there are far more efficient and productive programs to start off with.
Especially as a beginner, you can get a significant training stimulus without having to waste 2-3 hours of your day. How absurd. Think 80/20. I even think spending that much time would be more detrimental than beneficial in the beginning.
