The Shake Weight® by Jacked Up Fitness

The Shake Weight® didn’t just go viral, it tapped into a muscle science most people still don’t understand: fast-twitch activation, time-under-tension, and explosive power—the foundations of real strength and speed. We knew we had to bring it back so we reached out to the OG founder Johann Verheem and came to an agreement to collaborate on an all-new Shake Weight. Today Jacked Up Fitness is reintroducing the Shake Weight® to a whole new generation. No gimmicks, just pure power and performance. With new streaming workouts, athlete-grade routines, and science that backs what once made people chuckle, this tool is now a weapon—for beginners, athletes, and lifters chasing peak performance. Introducing the Shake Weight® by Jacked Up Fitness. All new, dialed in, and ready to fire.
