The Tunturi Platinum Strength Bag is designed for functional strength training. Five different weights are available, allowing the training load to be increased gradually. Weight bags are suitable for dynamic exercises such as squats, lunges, presses, lifts and rotational exercises. The shifting weight inside the bag adds a stability challenge and activates several muscle groups at the same time. The load can be adjusted easily to suit the exercise and trainee without interrupting the pace or intensity of the workout. The bags are designed for professional use. The durable PVC and Kevlar construction is made for daily lifting, dragging and dynamic exercises. The bags retain their shape, grip and structural integrity in high-traffic gyms and during intensive training programmes.
