12 Most Effective Smith Machine Leg Workout & Exercises

Using the Smith machine for leg workout such as quads, hamstrings, glutes and calves is one of the best methods for putting new muscle in your legs.

But, smith machine workout is an intense subject of controversy. Compared to free-weight squats, smith squats are entirely different.

It is important to remember that while free weights are often regarded as the top movements to gain muscle and strength, using Smith machines can also result in high amounts of muscle growth and strength.

Note, that if you are doing leg exercises on the Smith machine, it is key to set the safety racks and thoroughly understand movement mechanics with free weights as well. This will help optimize strength, movement, and increase overall performance.

To address this topic, we intend to go through the proper form, technique, and Pro-tips

Benefit Of Smith Machine

A Smith machine leg workout has many potential benefits. Below are some of the most common reasons why you should use smith machine during leg workout.

1. Increases Muscle Isolation

Smith machines are very effective at isolating the quads, hamstring, glutes and due to the ability to change body position and not worry about stabilization. There are also many variations, so you can hone in on other muscles.  

This is why even pro bodybuilders use the Smith machine for their leg workout

2. You Do Not Need a Spotter

The bottom of every Smith machine has a catch system. This catch system acts as a sort of replacement for a spotter.

Basically, you can repack the weight at any moment using the available hooks. 

3. Experienced Lifters Can Lift More

Smith machines remove much of the need to stabilize. For experienced lifters, this means more weight and volume, and therefore, more significant gains. 

4. Reduced Chance of Injury

Your chances of injuries are reduced because of a lifter’s ability to focus on form and the catch system. However, this, of course, does not translate to a zero percent chance of injuries. Like any exercise, you need good form and technique. 

12 Best Smith Leg Workout

Below are 12 leg exercises that can be done on a Smith machine to build leg strength, increase muscle hypertrophy, and enhance fitness.

1. Smith Machine Squat

Squats on a smith machine help to stabilize your core and keep your posture in the correct position while doing a squat.

The Smith machine squat allows you to safely squat a heavyweight without a spotter. Just make sure that you use the safety pins.

An advantage of the smith machine squat is being able to place your foot stance further forward than usual and target more of the glutes and hamstrings, rather than the exercises being quadriceps-dominant.

Smith Machine Squat

Muscles Worked

Primary: Quadriceps, gluteals.

Secondary: Hamstrings, adductors, spinal erectors, Abs

How To Do Smith Squat

  1. Stand on a Smith machine so that the barbell is behind your shoulders and slightly below your neck, grasping it just outside your shoulders. Twist the bar to unrack it.
  2. Grasp the barbell with palms facing forward and hands wider than shoulder width apart.
  3. With your chest high, head forward, and back slightly arched, bend your knees and hips. Inhale as you slowly lower the barbell by getting into a squat position.
  4. When your thighs are parallel with the floor, exhale and push off with your legs to reverse the movement and return to the starting position.


  • Keep your back straight, torso upright, head up, and feet flat.
  • Start light and add weight gradually, allowing your legs and lower back to adapt. Concentrate on form.

2. Smith Front Squat

The smith front squat is another great exercise for your leg workout, and it works the same target and synergistic muscles.

However, the smith front squat recruits more stabilizer muscles, including various back muscles, your shoulders, and your chest.

It is more advanced than the barbell squat. Front Squats with barbell helps build entire thighs and focuses especially on the outer thigh region.

Smith Front Squat

Muscles Worked

Primary: Quadriceps, gluteals.

Secondary: Hamstrings, adductors, lower back, abs.

How To Do Front Smith Squat

  1. Place the bar just underneath shoulder height.
  2. Hold your arms straight out, step on a Smith machine and get the bar on your shoulders in front of you. Cross your arms by placing each hand on its opposite shoulder.
  3. Take a breath and unrack the bar by rotating your wrists back to move the safeties.
  4. Maintain the natural arch in your lower back and keep your head directed forward.
  5. Perform a squat, bending your knees and driving your hips back to lower yourself until your thighs are parallel to the floor.
  6. From this position, push yourself back to the starting point.


  • Start light and add weight gradually, allowing your legs and lower back time to adapt.
  • Keeping your elbows high is an integral part of the proper front squat form.

3. Smith Machine Stiff-Legged Deadlift

If you’re looking for a straightforward leg workout that you can do with a smith machine to build mass and strength, then stiff leg smith deadlift, is a great staple exercise to get you started.

It is a variation of the deadlift and an exercise used primarily to target the muscles of the hamstrings and gluteals.

The stiff-leg deadlift for hamstrings requires a lighter weight than that used during traditional powerlifting for strengthening the lower back.

Smith Machine Stiff-Legged Deadlift

Muscles Worked

Primary: Hamstring, Gluteals.

Secondary: Spinal erectors, Quadriceps.

How To Do Smith Stiff-Legged Deadlift

  1. Set the Smith bar to thigh level and stand facing the barbell with your feet around shoulder width apart.
  2. Grab it with an overhand, shoulder-width grip. Keep your back straight, head up, and hips low, lift the barbell into a standing position.
  3. Flex your knees a little and push your hips backward and slowly lower the barbell down the front of your legs.
  4. Lower the bar down as far as your hamstrings will let you comfortably. Now engage the hamstrings and begin to raise the bar straight back up.
  5. Repeat for the desired number of reps.


  • Keep your knees stiff, your back and arms straight, and your head up.
  • Do not allow the bar to drift away from your body during the lift. Keep the barbell close to your body.
  • Your eyes should be facing up and your shoulders back. This will prevent your lower back from rounding.

4. Smith Leg Press

The Smith machine Leg Press is an alternative option if you don’t have access to a leg press machine. The Smith machine leg press utilizes a more vertical pressing motion than the traditional 45 degree leg press.

But using a Smith machine to leg press is a bit “dangerous” than with a leg press machine, but if you set the safety bars up, you’ll be fine. 

Smith Leg Press

Muscles Worked

Primary: Quadriceps.

Secondary: Gluteals, hamstrings, adductors.

How To Do Smith Leg Press

  1. Lie on your back and place your midfoot on the barbell, feet shoulder-width apart.

  3. Inhale, and lower the bar by bending your knees and hips until your thighs touch your rib cage.
  4. Forcefully push the bar back up and exhale. There’s no need to fully lock out your knees.
  5. Repeat for the desired number of repetitions.


  • Re-racking for this exercise can be tricky due to the way the smith machine is designed; you will most likely want to enlist the help of a spotter with the exercise to ensure that you don’t risk injuring yourself.
  • Always, start with smaller weights if this is your first time.

5. Smith Lunge

When doing leg workout with smith, them must do smith lunge, as it is a brilliant exercise that helps you to strengthen your legs without hurting your knees.

  3. Drive through the front foot and extend the knee as you return to the starting position.
  4. Repeat for the desired number of repetitions.


  • Bend as far and low as possible without losing form.

7. Smith Step Up

The smith step-up is a great exercise for building lower-body strength and power. This exercise targets the quadriceps and also involves calves and glutes & hip flexors.

8. Smith Hip Thrust

The hip thrust is a popular exercise which is used to target the glutes and hamstrings for muscle and strength-building purposes.

However, the Smith machine allows you to load up on big weights and focus all of that loading into the glutes so that they get the best workout.
