A deficit deadlift is a normal deadlift done from a small raised platform, so the bar starts a few centimetres lower than usual relative to your feet. That tiny change makes the first part of the pull much harder, and it's the reason strength coaches reach for it when a lifter's deadlift stalls just after the bar leaves the floor. If your lockout is fine but the start feels glued down, this is the variation to add.
It's an accessory, not a replacement. You'll lift less weight than normal, and that's the point: you're buying extra range and a harder start in exchange for load. Nail the conventional deadlift first.
You'll need a barbell, plates and a stable surface 2.5cm to 5cm high. Stacked rubber gym tiles, a thin lifting platform or a single bumper plate lying flat all work, provided nothing slides.
Body shape changes which deadlift suits you, so it's worth knowing before you pick the deficit version to train. A study of 47 lifters new to deadlifting concluded that sumo may give a slight mechanical advantage to people with longer torsos, while conventional suits those with shorter torsos (anthropometrics and deadlift variants). Run the deficit in whichever style you already pull best, since the aim is to strengthen your own start position, not to switch styles.
Lower than you think. For most people 2.5cm to 5cm is the sweet spot, the thickness of one or two change plates or a pair of rubber tiles. That's enough to hit the start position hard without your spine rounding.
Bigger deficits of 7.5cm to 10cm suit lifters with very good hip mobility, and sumo pullers rarely need more than 2.5cm, since a wide stance already puts you low. A simple test: set up at your chosen height with an empty bar and look side-on in a mirror or at a phone video. If your lower back rounds before your hands reach the bar, lower the platform.
Going too high. A 10cm deficit with a rounded back teaches nothing useful. Start at 2.5cm.
Standing on something unstable. Loose plates on a hard floor can slide, and a gym step can tip. Use tiles, a platform or a single plate flat on rubber flooring; a decent gym flooring setup makes this easy at home.
Hips shooting up first. If your hips rise and your chest stays down, you've turned it into a stiff-leg deadlift from a hole. Drop the weight and think "chest and hips rise together".
Letting the bar drift forward. A longer pull gives the bar more time to swing away from your shins. Keep your lats tight and drag it up your legs.
Treating it as a max-out lift. Heavy singles from a deficit add risk and little benefit. Keep it in the 3 to 6 rep range.
The NHS recommends strength work on at least two days a week for adults (NHS physical activity guidelines), so a deficit pull fits comfortably into a twice-weekly lower-body routine. Use a lifting belt for heavier sets if you already train with one, and straps once grip becomes the limit.
It's a conventional or sumo deadlift done standing on a raised platform, usually 2.5cm to 10cm high, so the bar starts lower relative to your feet. That longer pull makes the start of the lift harder and trains you to break the bar off the floor with more speed and better position.
Most lifters get the best results from 2.5cm to 5cm, roughly the thickness of one or two bumper or change plates. Go above 7.5cm to 10cm only if you can keep a flat back at the bottom, because the extra depth mostly just forces your spine to round.
Start at around 60 to 70 percent of your normal deadlift and work in sets of 3 to 6. Most people can handle roughly 80 to 90 percent of their regular max once they're used to the movement from a small deficit, less from a larger one.
No, they're an accessory. Use them to fix a slow or ugly start off the floor, or to add leg drive and range. Your main strength work should still be regular pulls from the floor.
The same as a conventional deadlift: hamstrings, glutes, spinal erectors, quads, lats, traps and grip. The lower start position asks more of your quads and hamstrings at the very bottom of the lift.
Yes, as long as you have a barbell, plates and a stable platform. Two thick rubber gym tiles or a sturdy lifting platform work well. Never stand on loose plates or a wobbly step.
