The BB back extension eliminates the struggle gripping weight plates / kettle bells for added resistance, when performing the hyperextension exercise.
The Selectorized Back Extension machine, allows you to conveniently hold onto a barebell for the added resistance, and avoids weights being dropped to the floor.
The multiple height adjustments is ideal for any user, it helps you target anywhere between hamstrings / glutes and lower back.
With dual usage, it can also be used for leg swing exercises with ankle strap attachment. You can adjust the height of the handle bars to suit the user for stability during the exercise.
Why do back extensions?
Back extensions maintains the tension throughout the entire range of motion.
Back extensions decompress the spine at the bottom.
To properly load the posterior chain you need only a small amount of weight, compared to many other exercises
Switch to unilateral back extensions and you need even less load.
