Mindsip insights from this episode:
Measure grip strength with a $20 dynamometer for health insights
For about $20, you can buy a grip strength dynamometer on Amazon to perform a bonus test of your overall strength and health.
Measure biological age with six free at-home tests
You can get a snapshot of your biological age using six free tests you can perform at home to establish a baseline for improvement.
Relate pushup performance to biological age
Your performance on a physical test, like continuous pushups, can be directly equated to a biological age; for example, 40 pushups for a female is equivalent to age 18.
Test functional strength with the ten-point sit-rise test
Test your functional strength with the sit-rise test, where you start with 10 points and lose one for every body part used for support while sitting and rising.
Utilize balance test to predict all-cause mortality risk
The eyes-closed, one-leg balance test is a good predictor of all-cause mortality for people over the age of 41.
Test your reflexes with reaction time app
You can measure your reaction speed, which declines with age and is more pronounced in women, using an app called 'Reaction Time and Reflex Test'.
Prioritize waist-to-height ratio over BMI for better health assessment
The waist-to-height ratio is preferred over BMI by many because it more accurately reflects visceral fat, with a target ratio of less than 0.5.
