Machine Back Extension (Back)

The machine back extension is an isolation exercise for the erector spinae muscles which allow us to maintain an upright posture. The back muscles also help us to bend, twist and turn so it’s imperative that these muscles are strong enough to support our daily functions. Now, since the back is a large area of muscle, sufficient work volume is necessary to promote growth and develop maximum strength gains.

But, it’s best to use lighter to moderate weights with the back extension machine because the lower back is a sensitive area, and too much resistance can be dangerous. However, it’s a very effective isolation exercise if performed in the moderate rep range which promotes optimal safety.
