It’s a potluck, so bring your favorite brunch dish to share. We’ll have a sign-up sheet at the gym so we don’t end up with all the same food.

Multiple studies show a strong link between grip strength and longevity. Good grip strength reflects overall health, muscle mass, neuromuscular function, and better cardiovascular health. It’s also tied to slower biological decline and plays a role in reducing the risk of falls and fractures by reflecting overall strength and stability.

Heavy Farmer’s Carries are one of the best ways to build grip strength, while also improving bone density and developing serious core stability through dynamic movement. Pair them with rowing and you’ve got a killer combination 😅

We don’t just train to look good, we train for health and longevity 💪 (but the hard work definitely looks good on you 😉)
