(1 customer review)

Unlike your average sandbagโ€”the one that comes in multiple sizes, takes up too much space, and ends up as a โ€œdecorativeโ€ doorstopโ€”our multi-functional sandbag gives you four weights in one. At-home gym clutter, be gone!

Complete with four pre-loaded 5kg inserts, adjusting the weight is as simple as unzipping a compartment to strip out or add weight in seconds for a custom workout, everytime. Whether you’re lifting, squatting, or carrying, this sandbag over delivers on all your functional fitness plans straight out of the boxโ€”no set-up needed.

Designed to tackle strength, balance, and endurance, the only limit is your imagination (but we have workout inspo for that tooโ€ฆ)
