Smith Machine Bulgarian Split Squat

The Smith Machine Bulgarian Split Squat is a strength exercise in a Smith machine for your quads. Share of the load in the Zulta muscle model: gluteus maximus 26%, quads (vastus lateralis) 15% and quads (vastus medialis) 13%.

Level: IntermediateEquipment: Smith machineMulti-joint (compound)Unilateral: one arm or leg at a time

How to do it

  1. Place a flat bench behind the smith machine and set the bar at shoulder height.
  2. Step under the bar so it rests on your upper traps, grip it and unhook it.
  3. Place the top of one foot on the bench behind you and the front foot slightly in front of the bar line.
  4. Lower straight down until the front thigh is parallel to the floor.
  5. Push through the front heel to rise, then switch legs after the set.

Tips

  • Test the foot position with an empty bar before loading.
  • Keep the torso upright: the bar path is fixed.

Common mistakes

  • Setting the front foot directly under the bar so the knee jams forward.
  • Pushing with the back foot on the bench.
  • Cutting depth short.

Share per muscle in the Zulta muscle model. The model spreads the load of one rep over 40 muscles, based on EMG and biomechanics research.

Rear foot on a bench makes a longer stride and puts more of the load on the front leg, mostly its glute. A split stance loads the front leg's quads and glute max, the glute medius and adductors keep the knee and pelvis in line, and the trunk resists the narrow base.
