The Short Version
No recognized scientific or clinical standard identifies exactly seven benchmark exercises for assessing age-related fitness. The gold-standard Senior Fitness Test contains eight tests, the Fullerton battery has six, and the WHO explicitly states no fixed set of seven exists. The only sources citing seven exercises are low-authority lifestyle outlets — and each lists entirely different exercises, revealing no unified protocol. The number "seven" appears to be a popular media framing choice, not a validated standard in gerontological fitness assessment.
