If you, like me, feel like dropping several F-bombs over the course of a workout, consider letting them fly. Research tells us that it can actually make your workout better, and Beachbody is testing that theory with its brand new program, 6 Weeks of the Work [1], which comes with — yes — an explicit language warning.

"I call it primitive vocalization," said Amoila Cesar, the Beachbody supertrainer who created 6 Weeks of the Work. Amoila, who has also trained pro athletes, describes his style of training as a hybrid cross of strength and conditioning with the goal of transforming you both physically and spiritually. Judging by the intense preview video [2], that combination creates an extremely challenging program, so it's no wonder Amoila and the crew behind him let off steam with a few choice words here and there. "My training is intense," he told POPSUGAR. "Clients [and me] express what we feel, and sometimes it comes with a word or two, and those words usually are explicit, but only in a motivating way!"

The research backs him up. Although no one quite knows why, multiple studies have shown a link between swearing and increased power [3], both in grip strength [4] and on an exercise bike, and pain tolerance [5]. According to psychologist Richard Stephens, who led both studies, swearing may trigger the sympathetic nervous system [6], aka the "fight or flight" response, which increases your heart rate and pumps your body with adrenaline. A simultaneous analgesic response can dull your perception of pain, making it easier to fight through the difficult parts of a workout.

So if you've ever thought that it just feels good to swear during that last burpee, you're not wrong. A vocal response is natural, whether you're grunting, yelling, or dropping an F-bomb. As Amoila told POPSUGAR, "It's a way to release and find strength in times of need."
