Dumbbells and kettlebells are a great way to amp up any routine, but they’re not the only weights at the gym. If you’ve never picked up a medicine ball, there’s no better time than now. This sandbag-meets-basketball is perfect for core training since it allows you to easily move and balance the weight in ways dumbbells may not. Best of all, medicine balls come in different weights and sizes, so even if you’re new to working out, there’s one to suit you.
