According to leading orthopaedic specialists weak lumbar extensors muscles may be responsible for up to 80% of all back problems.

New Element Training is the right partner for anyone seeking to prevent or actively tackle back pain.

Our MedX medical Lumbar Extension (MedX LE) therapy machine allows us to accurately test the strength of your back. We measure the strength of back extensor muscles at various angles. We also measure spinal mobility and identify any muscular imbalances. We then compare the results with the norms for those with a healthy back and identify any muscle or functional weakness. The data from the back test is an excellent tool and helps us create an effective personal training program for you. We can repeat the test at regular intervals and this provides objective evidence of your progress.

How MedX LE works:

MedX LE with Theo Smith

When you have chronic low back pain, your back muscles typically are in spasm, preventing your back from moving smoothly. When you use the MedX LE machine, you are ‘forced’ to move your lower back. This movement can actually feel good, just like if you hurt your elbow or knee, you move it back and forth to help ‘work it out’.

The movement your low back goes through on the MedX LE machine helps increase your range of motion, the amount your back is able to move. This movement stimulates the pumping of fluids into your spinal discs and helps lubricate your joints. All of these factors can help your body naturally heal injured spinal tissue and relieve back pain.

The MedX LE machine isolates your lumbar extensor muscles by tightly holding your legs and pelvis in a position that eliminates them from the movement (Fig. 2).  This ultimately forces your deep back extensor muscles to do all the work. By isolating these muscles, they quickly regain lost strength and most people feel relieved of their low back pain.

The key in strengthening the deep back extensor muscles is eliminating the stronger gluteal (buttocks) and hamstring (rear thigh) muscles from the movement chain. This can be achieved through MedX’s proprietary pelvic stabilization system (Fig. 2).

When using a chain of muscles the body will use the stronger muscles first. Therefore any lower back exercises that rotate the pelvis (Fig. 1) are more of a gluteal and hamstring exercise and do nothing to strengthen the deep back extensor muscles.  However, when the pelvis is properly stabilized and neutralized from the movement, we can directly target the small muscles of the spinal column (Figs. 2-3).


On your first visit to New Element Training, you will be asked to complete a questionnaire so that we can assess your current condition. If there is no evidence of a significant health problem, this is followed by a careful introduction to strength training. Your instructor will create a personal program based on your specific training objectives.

You are also able to receive regular check-up sessions and program modifications. This will ensure that your training is successful.
