One of the most versatile tools you’re probably not using, a sandbag is great for when you want to work out but also don’t want to spend all day working out. With a sandbag, the centre of gravity is always shifting, because the sand moves back and forth, causing your core to engage in a different way than with a stable weight, even when you aren’t doing a core-focused exercise. What does all that mean? It means you’re getting more bang for your buck with every movement. ~ Berceste
