Deadlift Max Calculator

Estimating your deadlift max

Deadlift estimates from higher-rep sets tend to run less accurate than squat or bench estimates, since grip and lower-back endurance often fail before the prime movers do. A 1 to 5 rep test set gives the most trustworthy number.

Conventional and sumo deadlifts recruit different muscles and typically produce different maxes for the same lifter. Keep your test set in whichever stance you're estimating for.

Compare your result to the strength standards calculator, check what percentages to program next with the one rep max calculator, or convert to kilograms with the kg to lbs converter if that's what your log uses.

Where these numbers come from

The formulas and default values in this calculator are based on:

• Epley (1985), Brzycki (1993), Lombardi (1989), and O'Conner et al. (1989) 1RM prediction formulas

These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.
