A long drink and a thorough foam rolling session. What else could you need after a workout? And Big Bertha is a tool for both: It’s a forty-ounce water bottle made of recycled stainless steel and wrapped in high-density, nontoxic EVA foam. The lumps and grooves hit hard-to-get spots and provide extra depth to your roll. And it can take 350 pounds of pressure, so you can really lean in.
