Why is proper placement so important?

The Pulse Device is meant to be placed on or near the muscle belly. An easy way to think about the muscle belly is that it’s the thickest part of a muscle where the most fibers are located. The muscle belly is what contracts and generates force, causing the movement of the muscle at the joint it crosses. By sticking your Pulse Device on or near the muscle belly, it ensures that the vibrations engage the maximal amount of muscle spindles, which are the key proprioceptors that allow our device to create better sensory feedback and prime your muscle(s) for deeper and stronger contractions.
