What you'll gain

• Adds hamstring range at the bottom without adding external load.

• Trains the hamstring at long muscle length on one leg at a time.

• Gives a progression step for users who have outgrown the flat version.

Step-by-Step Instructions

1. 1

   Set a stable platform one to three inches high and stand on it with one foot.

2. 2

   Hold a dumbbell and shift your weight onto the standing leg.

3. 3

   Soften the standing knee and set your shoulders back.

4. 4

   Push the hip back and let the free leg extend behind you.

5. 5

   Lower the dumbbell past the level of the platform, keeping the hips level.

6. 6

   Drive the hip forward to stand, then finish the set and switch sides.

Common Mistakes

• Using a platform so tall that the back rounds before the hamstring reaches its limit.

• Letting the free hip rotate open, which turns the hinge into a rotation.

• Standing on an unstable riser, which makes balance rather than the hamstring the limit.

• Keeping the same load as the flat version, which is heavier through the added range.

About This Exercise

The deficit version stands the working foot on a low platform so the dumbbell can travel below the level of the foot. Everything else matches the standard single-leg RDL: soft standing knee, free leg extending behind, hips level, spine long, dumbbell tracking down the standing leg. The extra couple of inches load the hamstring at a longer muscle length, which is where hinge variations do most of their work. The turnaround belongs at the point where hamstring length stops the descent, and a deficit simply moves that point lower. The clip is the range extension asset for a hinge progression: same movement, one visible change. It fits dumbbell equipment filters, advanced posterior chain blocks, and progression content showing range rather than load as the next step.
