The Terra-Core is a culmination of everything we know about training and strengthening the human-machine. It’s a balance trainer that doubles as a fully functional bench. It partners seamlessly with dumbbells, kettlebells, medicine balls, TRX, and all other fitness accessories. The bottom side offers push-up handles and other exercises to help build balance and agility. It's optimal for doing crunches, planks, and building abdominal, shoulder, and leg muscles. Built to commercial standards, the Terra-Core is tough enough for any at-home gym.
