Ditch the Scale – Track Grip Strength and VO2 Max
Show notes
The scale is measuring the WRONG thing about how well you’re aging.
I want you to stop looking at the scale as the ultimate measure of how well you're aging and start paying attention to the performance markers that reveal what your body can actually do. In this episode, I break down why grip strength, VO2 max, muscle quality, and mitochondrial health can tell you so much about your future strength, energy, resilience, and independence. I'll also show you how resistance training, protein, recovery, and targeted muscle support can work together to help you build a longer health span and strength span.
What you’ll learn:
(01:42) Why body weight and the scale fail to show how strong, capable, and resilient your body really is.
(02:44) How grip strength can serve as a simple proxy for overall muscle strength and neuromuscular function.
(03:36) Why VO2 max reflects aerobic capacity and is strongly connected with longevity and resilience as you age.
(04:30) How you can measure grip strength and estimate VO2 max using tools like a dynamometer, the Rockport one-mile walk, or a three-minute step test.
(05:12) Why muscle supports metabolism, blood sugar regulation, balance, mobility, independence, and recovery.
(06:04) How health span differs from strength span and why physical capability matters for making your later years worth living.
(07:31) Why mitochondrial function and cellular energy can become limiting factors for muscle strength, endurance, and recovery with age.
(08:17) How urolithin A, mitophagy, resistance training, and protein fit into JJ's muscle-first strategy for aging powerfully.
