General rule of thumb is that the back rest be at more or less a 90-degree angle.

Feet approx. 60 cm apart.

Lower weight so that knees are bent at approx. 90 degrees or slightly less.

Push back up to original position and repeat.

Apply resistance while lowering the weight as well, as most people lower the weight and then only apply resistance when pushing it back up.

- Stretch before, during and after the exercise

- Keep your back straight.

- Don't overload machine, as this exercise can add pressure to the abdominal and hip area.
