QUALITY CONSTRUCTION
Each sand filler is equipped with a double layer of Velcro, folding with outside binding reassuring you can throw them around without any sand leakage. Please avoid all sharp objects and any liquids. Sand is not included.
STABILITY & INSTABILITY IN ONE
Simply fill up the sand filler with play sand for compound workouts such as bicep curls.
Instability increases strength in our joints and core strength. Simply release sand some out, allowing the sand to shift side to side while you focus on maintaining the adjustable sand filler with minimal to no movement.
0-100LBS REAL QUICK

GET A GRIP
No excuses! We all are lacking motivation and determination. Each adjustable sand filler is equipped with a handle to use as a dumbbell / kettlebell.
BEFORE OR AFTER, YOU DECIDE!
