What practical improvements have you noticed since working out? I carried three grocery

what it claims

Regular resistance training tangibly transforms quality of daily life by strengthening physical autonomy, ease of movement, and self-confidence, particularly as one approaches their forties and beyond.

holds up

The community strongly converges on this finding, validating the idea that functional strength gains go beyond simple aesthetics.

The community strongly converges on this finding, validating the idea that functional strength gains go beyond simple aesthetics. Scientific research broadly confirms these benefits: meta-analyses (such as those published in 'Sports Medicine') demonstrate that resistance training significantly improves muscular strength, mobility, and bone mineral density in adults, especially during periods of hormonal transition. The link between muscle strengthening and the reduction of joint or back pain is supported by numerous randomized controlled trials (RCTs), which highlight improved structural stability. Improvements in balance and the ease of performing household tasks are also well-documented in the literature on active aging. Certain benefits mentioned, such as increased libido or higher energy levels, are observed in observational studies, although the precise mechanisms may vary from one person to another. There is no notable exaggeration here; the accounts reflect a normal physiological adaptation to progressive overload.

What the graded evidence says

Evidence
B

Linked to, not proven to cause.

Effect
all-cause mortality by muscle strength (grip) and by muscle mass vs strength — grip strength: HR 1.16 (95% CI 1.12-1.20) per 5-kg lower grip, 42 cohorts, ~3M people; low muscle strength independently ~2x mortality odds regardless of muscle mass
Measured on
community-dwelling and older adults

What’s uncertain

This is an association from observational studies, not proof that adding muscle causes longer life. Strength is a stronger predictor of survival than muscle mass by itself.
