Four minutes of daily resistance training can quadruple fitness in older adults

What the research found
Study (randomized). Penn State College of Medicine researchers (Sciamanna and colleagues) report in PLOS One that 97 adults (mean age 74) were assigned to 12 weeks of a four-minute daily FAST-2 circuit—push-ups, chair stands, two-arm rows, and stair stepping, 30 seconds each with 30-second rests—or no extra program. Baseline activity averaged about 18 minutes a week. The circuit group gained 4.2 more 30-second chair-stand repetitions, 3.6 more seconds of one-legged stand, and 2.3 seconds faster sit-to-stand. This is functional training, not a supplement protocol and not a diagnosis. Educational movement notes.
Evidence level: Clinical trial. This is among the stronger kinds of evidence, but one study rarely settles a question.
