@johnmoyerbass: 60 second dead hang 💪🤘 Grip strength is one of the strongest predictors of longevity. I keep reading that it correlates with how long you’ll live more closely than almost any other simple fitness marker. Most people fail in 20-30 seconds. This exercise is also great for decompressing the spine and for shoulder mobility. Try it today. See where you stand. Stay Metal. 🤘 #deadhang #gripstrength #longevity #Fitness #challenge
