Increase in deadlift throught squatting?

[The_GOAT]

Would it be unusual to see a large increase in deadlift strength (say, 200 pounds) without doing any deadlifts and solely squatting?

[Adam Skillin]

For a novice trainee, not unusual at all, although it brings up the question of why he's not deadlifting. Are you talking about going from 100 lb to 300 lb? I think it would be more rare to go from 400 to 600 without actually deadlifting. Is this a hypothetical question, or "someone you know?"

[The_GOAT]

Purely Hypothetical.

[Adam Skillin]

If a weak person gets very strong by squatting, he'll deadlift a lot more than he would have before. If he trains the deadlift, he'll deadlift more than he would have otherwise. Is this not intuitively obvious?

[The_GOAT]

Would have been if I had thought about it.

Zercher Squats will increase your Deadlift.

Squateadlift transference is dependent upon anthropometry and the technique employed in both movements. The fact that squat:deadlift transference is less than 1:1 is universal. That is, for every pound you add to your squat, no matter your anthropometry or the technique you employ, you will certainly not get one pound on your deadlift. Otherwise, there would be zero point in actually training the deadlift due to training economy.

Some people have extremely low transference between the two movements. If you're using SS style technique, the transference should be relatively high as long you keep your squat stance width in check and avoid trying to maintain an upright back angle. However, it isn't difficult to see why wide stance monolift squatters who don't squat very deep might not get much carryover to their conventional deadlifts from improving their squat.

I've actually analyzed the technical pairings of the Top 5 American powerlifters in every weight class up to 275lbs. Out of these 40 lifters, 12 pull sumo (30%). Of these 12 lifters, four use a medium (defined as ~shoulder width) low bar squat and seven use a wide stance low bar squat. Out of the 28 conventional pullers, 16 squat high bar and 12 squat low bar. Of the 12 low bar squatters, 10 used a medium or a wide stance. Of the 16 high bar squatters, 13 used a narrow or a medium stance. 13 of the 28 conventional pullers used a medium stance regardless of bar position (with some very narrowly being classified as wide). Further still, most of the wider squatters who pulled conventional used knee wraps and a monolift.

Obviously, you can draw your own conclusions, but it should be fairly obvious that wider low bar variants have better carryover to sumo (duh). The top conventional pullers use every stance and bar width combination imaginable. For non-wrapped lifting, the top conventional pullers tend to use a medium stance with either a high bar or low bar position. This also isn't very surprising.

Thank you for all that info.
