Starting position

  2. Exhale as you pull the barbell back up to the starting position by pushing your hips forward.
  3. Repeat.

Comments and tips

  • Keep your knees stiff, your back and arms straight, and your head up.
  • Keep the barbell close to your body to improve mechanical leverage.
  • If you can lower the barbell low enough for it to touch the floor, perform the exercise on an elevated platform.
  • Contrary to what some people think, the barbell straight-back stiff-leg deadlift targets your gluteus maximus and not your hamstrings. The reason is that, by flexing your knees even a little, you place your hamstrings in a state of mechanical disadvantage, thus forcing your gluteus maximus to work the hardest during hip extension. If you want to target your hamstrings, keep your legs straight (in which case the barbell straight-back stiff-leg deadlift will become the barbell straight-back straight-leg deadlift).
