How to load a standard 45 lb / 20 kg barbell to hit your 1RM. Shows one side of the bar.
Estimated maxes are a planning tool, not a chest-thumping number. Never test a true 1RM without a spotter, full warm-up, and dialed-in form. When in doubt, train at 80% — you'll get stronger faster than chasing a max every week.
