"Want to get results without the effort? We found a single nut job that supports your unrealistic expectations!"
Summary: If you only have an hour per week to work out and want to make the most of it
Nothing revolutionary here, but the advice is sound, and it's coming from a pretty reputable guy. Why is it getting so many downvotes? They're not saying this would be easy (and from experience, I can tell you it isn't), nor that it's a good way for beginners to get started.
Although...
you can get in and out of the gym in around 20 minutes. Do that 3 days a week
That might be a tad unrealistic. It takes five minutes to change and put away your bags. That leaves you with 10min to do your workout. Not worth it. Better to just do a full hour once a week and supplement with some bodyweight exercises at home.
Clickbait headline, and the article isn't exactly filled with substance either. Downvoted because it wasn't even worth reading, when a simple web search reveals much better resources for folks getting started.
