Frequently Asked Questions

What is a good deadlift?

For men: 2× body weight is intermediate, 2.5× is advanced, 3× is elite. The deadlift is typically the heaviest lift for most people.

Conventional vs sumo?

Both are valid competition lifts. Sumo uses a wider stance and shorter range of motion. Neither is inherently better — try both and use what feels strongest.

How do I avoid injury?

Maintain a neutral spine, brace your core, keep the bar close to your body, and do not round your lower back. Start light and perfect your form.

How often should I deadlift?

1-2 times per week is optimal for most people. The deadlift is very taxing on the nervous system and requires adequate recovery.

Is the Deadlift Max Calculator free to use?

Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
