In a landmark breakthrough meta-analysis, data collection has shown that lifting heavy weights is a waste of time, and the greatest health and fitness outcomes are gleaned from really long walks and yard work. Celebrities and fitness models break their silence on what it takes to achieve incredible physiques: the secret is to avoid all intense muscle contraction and just do a lot of incredibly time-consuming cardio and low-level activity.
We all know that I made up the headline and opening paragraph. Yet, most people behave as if it were the truth. I've run into many individuals over the years who are under some delusion that things will get better if they don't pick up heavy weights. I haven't ever seen a single example of improvement with the removal of intense muscle contraction. It would be contrary to all research. Not a single fitness model or celebrity who gets in shape does so by avoiding intense physical activity. But people operate their lives as if it's going to be true.
I don't recall hearing anyone say, "I'd love to have the body of a walker, gardener, or leaf raker." Activity is nice. And it's a really great starting point for the sedentary individual, in fact.
But I'm telling you, 30 minutes of heavy strength training beats hours of sweaty activity. Over the course of 42,000 hours of professional experience, I've witnessed hundreds of fitness professionals work hundreds of thousands of hours with members and clients. I've seen many people train for marathons only to find themselves in worse shape. I've seen people gain weight even though they are outside doing activity every day.
Nothing beats the outcome of a consistent practice of strengthening. Nothing.
