The often underappreciated yet extremely versatile and powerful classic sandbag is a multipurpose functional strength training tool with numerous benefits that are not possible to realize through traditional barbell training alone. The ZIVA Power Core Bag takes this dynamic, less easily controlled resistance that recruits more stabilizer muscles across the entire body, and updates it with heavy-duty nylon straps, a thick PVC skin, and large, easy identification weights numbers. This highly flexible tool allows users to enjoy a wide variety of compound lifts and combined compound lifts, a dream for full-body superset routines. The variable weight distribution of the classic sandbag is improved here with ZIVA engineering: plastic microbeads and a special sand-filled liner bag allow for more even yet still dynamic weight distribution during exercises while the bag’s airhole endcaps allow for safe compressed during intense exercise.
