Smith Single Leg Split Squat

Instructions

1
Stand upright in the Smith machine with feet shoulder-width apart, positioned slightly forward under the barbell. Place the barbell across the upper back and shoulders, gripping with hands slightly wider than shoulder width. Maintain neutral spine alignment with chest up and core engaged.
2
Set feet in a stance that allows for full knee flexion without forward knee cave. Engage core and take a deep breath to prepare for the descent. Ensure the barbell rests securely on the trapezius and rear deltoids, not the neck.
3
Lower your body by bending at the knees and hips simultaneously, descending in a controlled manner. Continue lowering until the thighs reach parallel to the ground or slightly below, maintaining an upright torso and weight in the midfoot. Keep knees tracking over toes without caving inward.
4
Drive through the midfoot and heels to extend the knees and hips, pushing the body back to the starting position. Maintain spinal alignment throughout the ascent and avoid locking out knees at the top. Exhale as you complete the concentric phase.

Overview

If you want to isolate and overload the Quadriceps, the Smith Single Leg Split Squat is an excellent addition to your routine. The mechanics of this Strength exercise specifically bias the Thighs, while the use of Smith machine allows for a smooth, natural resistance curve.

Benefits

  • Allows for a natural movement path that closely mimics functional daily activities.
  • Improves overall Thighs stability and proprioception during heavy loads.
  • Significantly enhances the structural integrity and power of the Quadriceps.
  • Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.
  • Promotes balanced muscular development by effectively recruiting the Quadriceps and associated synergists.

Pro Tips

Control the eccentric (lowering) phase of the Smith Single Leg Split Squat for 3-4 seconds to drastically increase time under tension.

Muscle Anatomy

The primary driver is the Quadriceps. However, the movement also recruits Gluteus Maximus, Hamstrings, Gastrocnemius, Erector Spinae to maintain control of the Smith machine.
