Workout Sandbag for Fitness, Heavy-duty Weight Training Sand bag with Empty Filler Bags for Full Body Exercises

INSTABILITY BUILDS STRENGTH | The sandbag is a unique type of weightlifting tool in that its weight constantly shifts back and forth from the center of mass, challenging the user to adjust and stabilize the bag’s ever-changing shape as it’s raised and lowered. This new FASPUP Sandbag capitalizes on this key fundamental by allowing the internal sand/weight to move more freely as you train, whether its during load carries, sprints, squats, lunges, or presses.
QUALITY HEAVY DUTY CONSTRUCTION | FASPUP weighted bags feature a 1200D Military spec polyester construction (water-resistant and machine washable) with double-stitched, reinforced seams. Each heavy sand bag also has 6 exterior carrier handles made from two layers of webbing with reinforced stitching—strong enough to handle any and all swinging, pulling, and twisting. A heavy-duty zipper and reinforced double-sealed inner liners are made for unmatched containment.
ADJUSTABLE & SMART DESIGN | Whether you’re a newbie or a pro, you can adjust the weight of the tactical sandbags to match your fitness level. Simply add or remove insert filler sandbags to customize the weight from 8-48 lbs for reduced resistance, or add more for a greater training exercise challenge of your choice. Three filler modular bags are included. Each weight lifting bag is optimized with 6 handles for a range of high or low rep fitness options.
BURST-PROOF SANDBAG FILLER | All filler bags are fortified with ripstop stitching and a double-layered Velcrotape stopping point. This helps prevent bursting, creates an air-tight seal, and makes the addition or removal of filler bags quick and easy. The heavy zipper on the outer shell ensures all the contents remain in place. DOES NOT INCLUDE SAND. Do not throw/slam filler bags or outer shell during use.

Also ideal for a circuit and cardio conditioning.
