Great post. Most people that go to the gym are mainly trying to look better so those people should be doing heavy lifting. Even most training calls for time with heavy weights. Thus, the 45 minute or so rule. You point out a major caveat: Most people are not going anywhere near their limits. Around 45 minutes of high weight/volume training, one should naturally notice a loss of power not quit prematurely due to a stopwatch. A (fat) person once told me she heard some advice that one should do cardio at a pace in which one will not experience heavy breathing and still be able to hold a conversation with the person next to them. What's next? Laying in bed as cardio? Beginner advice: It's better to go out and just do something rather than overthinking it. Look at the people who are skinny, ripped, massive, fast, or whatever your goal is and do what they do. Many people apply premature optimization to working out. Diet matters but guys in prison become huge on three square meals a day. Sets and reps matter but Arnold wrote something to the effect of, "I don't know why beginners worry so much about details. If you are bad at pull ups, do as many pull ups as you can, rest, repeat." The key is to push yourself and measure your progress to make sure you are actually improving.
