The Terra-Core is a culmination of everything we know about training and strengthening the human machine. Moving from a hard surface to a soft dynamic surface, when working out yields more efficiency and more benefits, while performing the same movements. Exercises performed on a hard surface are two-dimensional by nature. The Terra-Core engages core stabilizer muscles, adding a third dimension to every movement. We have performed independent studies demonstrating 4 times as many muscles being engaged on the Terra-Cores dynamic surface than the same exercise does on a hard, flat two-dimensional surface.
