The heavy duty , solid steel, yet portable G-CORE “landmine” will challenge your core in ways you never imagined possible. You can perform 1- and 2-arm movements and other rotational exercises simply by inserting any Olympic or Standard bar into the appropriatly sized pivoting sleeve at the unit’s base. Use the included Ergonomic 26″ Wide Wishbone Handle attachment for a workout that targets the shoulders, core and hips. The landmine treads the line between free weights and a fixed-plane machine. It allows freedom to move outside pre-set action lines, but not enough that you lose control or overload the weight. Learn proper joint alignment, synchronization and coordination of movement patterns to properly manage external loads that transfer to sports or real life movements. It also provides a great way to vary your workouts and provide serious overload and stimulation for the target movement. It helps you avoid potentially painful ranges of motion. The position of the bar matters. Because the bar is partially supported on the ground, you will lift less than the entire amount of weight of the system (i.e., the bar and plates). The amount of weight you lift relative to the amount on the bar is reduced as you raise it to a higher angle because more weight shifts to the end supported on the ground. The closer the bar is to the floor, the more weight you will lift, for example, a kneeling overhead press is actually harder than a standing press at the same weight. Also since the bar moves in a curved path, you have to get used to moving outside a linear path. Most people progress through an exercise from point A to point B in a direct line, but a landmine uses curved pathways, and this requires some acclimation.
