Symmetry Central has next generation patented exercise machines that address different parts of the muscular - skeletal framework. The Sky PressCycles exercise machines are premised on the Moschel Method® a scientifically sound and professionally endorsed principle of muscle rebalancing, recovery and strengthening based on Tetrahedron Biomechanics. By design humans are not perfectly symmetrical and in turn have a tendency to favor one side of the body over the other. Most obvious is the dominance of the right or left arm. However, that bias carries through to other appendices, the impact of which tends to strengthen internal muscles asymmetrically. While exercising, without a proper corrective mechanism, we tend to strengthen the favored muscles creating an even greater imbalance. When injured, this imbalance is exasperated since the injury tends to expand regionally by compensation and adaptation of then stronger areas of the body. Sky PressCycle is designed to target the middle of the Pectorals Major muscle, when used with shoulder width grip by symmetrically rotating the user’s legs through a peddle mechanism that causes the body to alternate evenly, instead of focusing on its natural bias towards one side over the other side of the body, while the user performs vertical weight lifts. This rebalancing causes an even strengthening of the Pectorals Major muscle.
