What Is Emsculpt? The non-invasive HIFEM (high-intensity focused electromagnetic) technology induces 20,000 supramaximal muscle contractions in 30 minutes. What exactly does that mean? “This [technology] is able to affect the muscle in a way that you couldn’t do voluntarily,” said Frank. “When you do a crunch or a squat, you’re activating about 50 percent of that muscle group every three to five seconds. This is activating 100 percent of the muscle 20,000 times in a 30-minute period.”
