Smith Stiff Legged Deadlift
- Intermediate
- Compound
- Rep-based
- Lower legs
- Upper legs
The Smith Stiff Legged Deadlift utilizes a fixed vertical path to isolate the hamstrings and glutes through a deep eccentric stretch. By removing the stability requirement of a barbell, it allows for intense focus on the hip hinge and posterior chain engagement.

Setup
- Position the Smith machine bar at mid-thigh height and stand with your feet hip-width apart, toes pointing forward.
- Grip the bar with an overhand grip slightly wider than your legs.
- Unlock the bar and stand tall with your chest up, shoulders back, and a very slight bend in your knees.
- Ensure your mid-foot is directly under the bar so it remains close to your body during the descent.
How to do it
- Inhale and initiate the movement by pushing your hips back as far as possible, keeping your legs nearly straight but not locked out.
- Lower the bar slowly down the front of your legs until you feel a maximum stretch in your hamstrings, usually just below the knees.
- Exhale and drive your hips forward to return to the starting position, focusing on pulling with your hamstrings rather than your lower back.
- Maintain a controlled 3-0-1-0 tempo, emphasizing the three-second lowering phase.
Form checklist
- Keep your back flat and spine neutral from head to tailbone throughout the entire lift.
- Maintain the same slight bend in your knees; do not let them turn into a squat as you descend.
- Keep the bar in constant contact with or very close to your shins to protect your lower back.
- Stop the descent immediately if you feel your lower back beginning to round.
Pro tips
- Focus on the 'mind-muscle connection' by imagining your hamstrings are rubber bands stretching and then snapping back into place.
- Keep your weight distributed toward your heels to better load the posterior chain.
- Avoid fully locking out your hips at the top to maintain constant tension on the hamstrings.
Make it harder
- Stand on a weight plate or low box to perform a deficit deadlift, increasing the range of motion and the hamstring stretch.
- Add a 2-second pause at the bottom of the movement where the hamstrings are at their longest length.
