Smith Rear Lunge
The Smith Rear Lunge primarily works the Gluteus Maximus, Rectus Femoris, with secondary activation of the Adductor Magnus, Gluteus Maximus, Rectus Femoris, Soleus and stabilizer support from the Biceps Femoris (Long Head), Erector Spinae, External Obliques, Gastrocnemius (Medial), Gluteus Medius, Gluteus Minimus, Quadratus Lumborum. It is a smith machine compound exercise at beginner difficulty.
A smith machine compound push exercise targeting the Gluteus Maximus and Rectus Femoris.

Instructions
- Preparation: With bar upper chest height, position bar on back of shoulders and grasp bar to sides. Place feet under bar or slightly forward. Straighten legs so weight is lifted. Disengage bar by rotating bar back. Place feet slightly forward. Execution: Step back with one leg while bending supporting leg. Plant forefoot far back on floor. Lower body by flexing knee and hip of supporting leg until knee of rear leg is almost in contact with floor. Return to original standing position by extending hip and knee of forward supporting leg and return rear leg next to supporting leg. Repeat movement with opposite legs, alternating between sides. Comments: Keep torso upright during lunge;flexible hip flexorsare important. Forward knee should point same direction as foot throughout lunge. A long lunge with feet slightly forward emphasizes Gluteus Maximus; short lunge with feet under the bar emphasizes Quadriceps.
