The 45 LB Ruck Weight Plate is constructed for the highest-level performance while increasing your resistance when walking, jogging, or running. This durable, heavy gauge cast iron weight plate features rounded ergonomic corners, smooth edges, and a single easy-to-grab wide-grip handle. Adding this rectangle ruck plate to your backpack for rucking excursions or tactical training improves your cardio by building strength and muscle mass and strengthening your hips and posture. With the backpack's weight pulling your shoulders and back into a proper alignment, your upper body becomes more comfortable and will maintain that posture in everyday life. In addition, the plate is an excellent alternative to traditional weight plates allowing you to perform multiple bodyweight exercises like squats, lunges, crunches, presses, and more.
