If you do pistol squats and back bridges while you travel, your deadlift will improve almost continuously until you hit diminishing returns at some value relative to your body weight. For example, I never deadlifted but did do (maybe 3 per leg, 2 sets) pistol squats and back bridges. First day I deadlifted 315 no problem, no where near my max.
My math suggests that at a decent level of proficiency, two sets of ~15 unweighted pistols and two sets of 10 back bridges would correlate to a 3RM deadlift of 2 to 2.5 x bodyweight.
My brother (similar height, weight, and build to me) did not do back bridges or pistols before deadlifting, and had trouble with 250 on the first day.
