FAQ
What is a good deadlift?
2x body weight is intermediate, 2.5x BW is advanced, 3x+ BW is elite for conventional deadlift.
Conventional vs sumo deadlift?
Both are valid. Sumo uses a wider stance reducing range of motion. Conventional is the standard in most federations.
How do I safely test deadlift 1RM?
Warm up progressively with sets of 5, 3, 2, then singles. Use a belt if needed. Stop if form breaks down.
Why is my deadlift higher than squat?
The deadlift has a shorter range of motion and uses more posterior chain. Most lifters deadlift 10-20% more than they squat.
