The claimWhat John actually said

In a Business Insider interview published in May 2026, after retiring from WWE, Cena described shifting his training away from heavy lifting toward mobility, cardiovascular work and knowing when to stop. He said he wants to be able to bury a squat when he is 85, and described 45 minutes of static stretching as worth the tedium for the way it makes him move afterward.

Why it mattersWhy this matters for longevity

Muscle and strength decline steadily from midlife, and that decline is what most often ends independent living

Strength work is one of the few habits with both cohort and randomized trial support behind it

Training for function rather than for a number is easier to sustain for decades

The evidenceWhat the science says

Pooled cohort data covering millions of person-years links muscle-strengthening activity to roughly 10 to 17 percent lower all-cause mortality, and the association holds after accounting for aerobic exercise. Randomized trials in older adults consistently show progressive resistance training improves strength, gait speed and the ability to rise from a chair, which are the measures that track with staying independent.

What the evidence does not show is that any of this guarantees a squat at 85. The trials run for weeks or months, not decades, and they measure function rather than lifespan. Heavy loading also carries real injury risk if progression or technique is poor, which is why the professional position statements emphasize supervision and gradual progression rather than intensity for its own sake.

TakeawayThe honest takeaway

The practical lesson

Two or three sessions a week of progressive resistance work, loaded to your own capacity and progressed slowly, is the version of this with evidence behind it.

SupplementsThe supplement angle: Protein and vitamin D

Support a habit, do not replace one

Adequate protein spread across the day and sufficient vitamin D are the two nutrition factors most often studied alongside resistance training in older adults. They support the training rather than substitute for it, and blood levels are worth checking with a clinician before supplementing.

Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
