Equipment needed

How to perform it

For strength, 3 to 5 sets of 4 to 6 reps with 2 to 3 minutes of rest are common. For hypertrophy, use 3 to 4 sets of 8 to 12 reps with 60 to 90 seconds of rest.

Execution and technique cues

• Stand tall on an elevated platform holding a dumbbell with extended arms in front of your thighs.
• Tuck your chin to your chest and begin curling your spine downward one vertebra at a time.
• Allow the weight of the dumbbell to pull you deeper into the stretch while keeping your knees fully locked.
• Reverse the movement by slowly unrolling your spine back to the upright position, starting from the lower back.

Common mistakes

• Bending the knees during the descent to make the movement easier.
• Rushing the movement or using momentum to pull the weight up.
• Using excessive weight before developing the necessary spinal articulation and flexibility.
