A physician who dislikes exercise is advocating for a surprisingly short routine to extend life. Dr. Christopher Sciamanna, a professor of medicine at Penn State, says that as little as four minutes of daily bodyweight movements can build strength and resilience for better longevity.
Sciamanna's approach targets people who currently do no exercise at all. "From a health perspective, the real goal is taking people from zero to one, to a little bit," he told Business Insider. His research focuses on the "minimal effect dose" of activity, making workouts less daunting for those who need them most.
The routine relies on simple, equipment-free moves like squats and push-ups performed at home. Sciamanna, who is 59, demonstrated a full-body workout designed to be completed in under 30 minutes per day, though benefits may begin with just four minutes of effort.
Critics caution that four minutes may not meet established guidelines for cardiovascular or muscular fitness, and individual results will vary. The claim is based on a single expert's opinion and preliminary research, not large-scale clinical trials.
