Strength Level Calculator.

Muscular strength independently predicts how long and how well you live. In large cohorts, people in the lowest third of strength for their age have markedly higher all-cause mortality than the strongest third, even after adjusting for aerobic fitness and muscle mass. Strength tracks the things that keep you independent late in life: the ability to rise from a chair, carry groceries, and catch yourself in a fall. Grip strength alone is one of the single best cheap predictors of mortality.

That is why the big barbell lifts are worth measuring. Bench, squat, and deadlift load the whole body through large ranges of motion, and where they rank for your bodyweight is a good proxy for total-body strength. This is the same reason the site tracks grip strength and the sit-to-rise test — different windows onto the same longevity signal.

The levels — untrained, beginner, novice, intermediate, advanced, elite — are based on relative strength: your one-rep max as a multiple of your bodyweight, benchmarked separately by sex and by lift. A 1× bodyweight bench and a 2× bodyweight deadlift are both roughly intermediate for a man; the multiples are lower for the bench (a smaller-muscle lift) and higher for the deadlift (the whole posterior chain). Relative standards are used instead of raw numbers because a 60 kg and a 100 kg lifter should not be held to the same barbell weight.

These bands are widely-used estimates, not official percentiles from a single registry, and they assume a true or well-estimated one-rep max. If you only know a multi-rep weight, estimate your 1RM first (a set of 5 is roughly 87% of 1RM).

The Wilks score solves the cross-bodyweight comparison problem for powerlifting totals. It multiplies your total (bench + squat + deadlift) by a coefficient derived from your bodyweight and sex, so a featherweight and a heavyweight can be ranked on one scale. This calculator uses the Wilks-2020 coefficients, the rebalanced version that better aligns men and women and the extreme weight classes. As a rough guide, a Wilks around 300 is a solid trained lifter, 400+ is competitive, and 500+ is elite.

To raise it, add strength to the total without adding bodyweight you do not want — progressive overload on the main lifts, enough protein (about 1.6 g/kg), and consistency over years. The number is a motivator; the underlying goal is the strength itself, which is what carries into your later decades.
