Setup
- Adjust the hyperextension bench so the top of the pad sits just below your hip crease to allow for full hip flexion.
- Place one foot securely against the footplate and under the ankle pad, then lift the non-working leg off the support.
- Hold a dumbbell firmly against your chest (goblet style) or hanging straight down with a neutral grip.
- Engage your core and pull your shoulders back to establish a neutral spine.
How to do it
- Inhale and slowly hinge forward at the hips, lowering your torso until you feel a deep stretch in the hamstring of the working leg.
- Exhale and drive your hips hard into the pad to pull your torso back up to the starting position using only the working leg.
- Squeeze the glute of the working leg at the top of the movement without arching your lower back.
- Maintain a controlled tempo, taking 2-3 seconds on the descent and 1 second on the ascent.
Form checklist
- Keep your chin tucked to maintain a neutral cervical spine throughout the movement.
- Ensure the movement occurs at the hip joint, not by rounding or arching the lumbar spine.
- Keep the non-working leg tucked or slightly behind you to avoid using it for momentum.
- Stop the ascent once your torso is in a straight line with your working leg; do not hyperextend.
Pro tips
- Turn the toe of your working foot slightly outward to increase the recruitment of the gluteus medius and external rotators.
- Focus on 'pushing' your heel into the footplate to maximize hamstring tension during the concentric phase.
- Keep the dumbbell glued to your sternum to prevent the weight from shifting your center of gravity and pulling you out of alignment.
Make it harder
- Hold the dumbbell at arm's length toward the floor to create a longer lever arm, increasing the demand on the hamstrings.
- Perform a 3-second isometric hold at the top of each rep to maximize peak muscle fiber recruitment.
Frequently asked
- What muscles does the dumbbell single leg hyperextension work?
- The dumbbell single leg hyperextension primarily targets the glutes and hamstrings, and also works the erector spinae as secondary muscles.
- What equipment do you need for the dumbbell single leg hyperextension?
- The dumbbell single leg hyperextension uses dumbbell.
- Is the dumbbell single leg hyperextension good for beginners?
- The dumbbell single leg hyperextension is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
