FLEX attaches to the barbell with internal magnets and a locking ring.
Attach the FLEX device like an end cap to the barbell and you'll feel the magnets lock it into place.
If the device is on you'll see the lights flash which indicates it's now registered that it's on the bar.
If you’re going to be dropping the weights, dumping the bar from a snatch for example - it is recommended tightening the device by turning the locking ring.
We also suggest using FLEX on same side of the bar each time just to help minimise any variance that might be a result of biomechanic differences between your left and right sides.
