But what if there was a way to get more out of your standard dumbbell workout?! @Powertecfitness took the typical dumbbell design and flipped it upside down making it even better. This new off-center design brings a unique approach to training especially when it comes to these curls like you see above. Using these we’re able to create two different types of workouts and workloads with just one single dumbbell. The added grip and wrist strengthening factors gives us a totally new way to experience the pump!! Working harder and smarter at the same time can make all the difference in the world. Pick up a pair today and curl it, with just one rep you’ll notice and feel the difference! .. 🚨WANT TO LEARN MORE?! 👉🏾Just click the link in my bio or go to powertec.com」7月22日 7時29分
