ARX was created based on scientifically-backed principles, ensuring that users receive the safest, most effective, and most efficient form of resistance exercise in the world. The machine uses motorized resistance and computer software to deliver the perfect workout every time, moving at a constant velocity that can be pre-set for any resistance training protocol. When you push, it provides you with the ideal amount of resistance at every moment during every repetition.

ARX delivers higher levels of mechanical tension, muscular damage, and metabolic stress to muscles compared to traditional weight training methods. As a result, an entire ARX workout can be completed in just 10-15 minutes, once per week. Several recent studies have concluded that achieving comparable results without ARX would require three 45-minute workouts per week using traditional weights.
In a recent study, the ARX Group achieved 2.5 times greater fat loss, 2 times greater muscle mass gain, 3.5 times greater cardiovascular fitness improvement, and 90% greater strength gains than the traditional weight lifting group over the course of 12 weeks, despite spending 72% less time exercising.

ARX is an incredibly safe form of resistance training, thanks to its advanced safety features that prevent users from accidentally injuring themselves by using too much weight. With computer-controlled resistance, the machine ensures that you are always in control – if you stop pushing, the machine stops resisting. This feature is especially crucial for those who are new to strength training, have a history of injuries, or as we age. With ARX, you are always acting on the machine, and the machine is never acting on you.

ARX’s advanced technology records every repetition and provides real-time data to users, allowing them to track their progress with precise accuracy. This feature eliminates the guesswork from training and motivates users to push themselves further toward achieving their fitness goals faster.
