F3/F3.1 Lower Back Machine

Meet the F3/F3.1, also known as the lower back machine. The purpose of this machine is to isolate and strengthen your lower back muscles. 

Why back strength is important 

Back strength plays an important role to play in long-term health, independence and longevity.  Strong back muscles help support the spine, reduce discomfort and enable you to move confidently in daily life. At Kieser, we use the F3/F3.1 machine to help build functional strength that can support how you move, work and live. 

Your lower back muscles help keep your body stable and balanced and are used in everyday movements, like standing, walking, lifting and twisting. Strengthening these muscles helps you to move better, improve your posture, and balance and to help manage lower back pain. Having weak lower back muscles may increase the risk of back pain or injury.   

How the F3/F3.1 works 

The F3/F3.1 is designed to support your lower back and strengthen your core safely. When you are using the machine, it keeps your hips almost completely still while being gentle on your knees, making it a safe and effective way for you to build lower back strength. 

How the F3/F3.1 helps 

Adding the F3/F3.1 to your training program will help strengthen your lower back muscles, making everyday activities easier, such as:  

  • gardening

  • loading things in and out of the car 

  • carrying your luggage, shopping or grandchildren 

  • recreational and sporting activities (such as golf) 

  • maintaining your balance (such as standing on public transport).

Technique Tips

  1. Make sure you're engaging your lower back in this exercise and that you aren’t pressing down with your legs or lifting your buttocks from the seat. 

  2. Keep your head neutral. Tilting your head back will make the exercise less effective and may cause neck tension. 

  3. Grip the handles loosely and keep your shoulders low. 

If you’d like to include the F3/F3.1 in your training program, arrange a review session with one of our exercise scientists. They can add it to your program, show you how to set up the machine and make sure you’re using it correctly.
