Does MedX® work better at strengthening the lower
back than other exercise devices?
Yes, much better. MedX® uses a patented method to immobilise
the pelvis and isolate the lumbar extensors. Research has
shown that pelvic stabilisation is indispensable when
strengthening the lumbar extensor muscles.
A study compared resistance training with and without pelvic
stabilisation in a group of 47 men and 30 women. The data
showed that post training isometric torque values describing
isolated lumbar extension strength improved only for the group
that trained with pelvic stabilisation and not at all
for the group without pelvic stabilisation (using systems
such as Cybex and Nautilus) when compared to the (no exercise)
control group.
