Hallo,
Ik gebruik zo'n rol tijdens het squattten. Nu las ik net het volgende tekstje:
'Question - Can I use a manta ray when squatting?
If you have had shoulder problems, the manta ray can be a pretty useful piece of equipment. It's use is certainly not advised unless absolutely necessary, because it lengthens the lever arm between the weight and the rotation point (i.e. the barbell and the hips), which can cause problems with the lower back. It can also "wobble around" atop the shoulders causing a load shift affect, which also can cause problems with the lower back.
However, if you are experienced enough with the weights to know you NEED a manta ray, then by all means, it is better to squat with one than to NOT squat without one.
If, however, you simply want to use a manta ray for comfort's sake, then don't bother squatting at all. The amount of pain tolerance from a hard, heavy set of squats will be too much for you if you can't take a little bar sitting across your shoulders. Perhaps you should take up a different hobby...knitting, for example.''
Uit het citaat kun je opmaken dat het problemen kan veroorzaken in je onderrug, mensen die hier ervaring mee hebben of dit kunnen bevestigen?
