1988 frail elderly strength study
At 52:35 · chapter starts 51:03
In 1988, a Boston doctor took the oldest, most frail residents of the Hebrew Rehabilitation Center for Aged and put them through an 8-week resistance training program — 1 exercise, 3 sets of 8 reps, 3 times a week. In an era when no doctor would recommend this, the results shocked: the average age of participants was 88, all had multiple chronic diseases, and yet the minimum strength gain was 61%, the average was 174%, and the maximum was 374%, with zero injuries. [1] — Sal Di Stefano "174% average strength gain at age 88: A 1988 study at the Hebrew Rehabilitation Center found frail 88-year-old residents gained an average …" 52:12 One participant, 92-year-old Dorothy Tischler, said she became younger and could walk better than her 72-year-old daughter. Sal and Adam connect the study to their own training careers: Adam notes that many of his 55-65-year-old clients who had never lifted reported being in the best shape of their lives precisely because strength training wasn't part of their generation's culture. Sal closes with stories of elderly clients he trained from near-total dependence to functional independence, including current client 'Mean Jean,' whose mood and attitude have completely transformed within less than a year of working with trainer Tyler at the Mind Pump studio.
The 1988 Study That Changed How We Think About Aging
In 1988, a Boston doctor trained the oldest, frailest nursing home residents to lift weights when no one had ever tried it. The results: average strength gains of 174%, a maximum of 374%, and zero injuries in 8 weeks. One 92-year-old participant said she could walk better than her 72-year-old daughter. It's the proof that it is never too late to build strength.
