The Marcy Inspire 4 home gym is completely iso-lateral giving the user greater freedom of movement. Each side of one’s body is responsible for exactly 50% of the load, which in turn improves muscle balance & coordination as well as develops the user’s core stabilizer muscles in the mid-section. The M4 gym is loaded with special features such as a lat tower that splits for a cable crossover exercise as well as a bench that rolls to the side to make the high pulley more accessible. The M4 also comes standard with a dual adjustable pulley column for important exercises like bicep curl & tricep extension. This pulley column has been designed to offer a quarter pulling ratio, so that each 4.53kg. weight plate offers 1.13kg of resistance. These smaller increments are important for smaller muscle groups. Undoubtedly the most well equipped home gym on the market today. Fully capable of turning any body into a hard body.
