@coreyjay.eyndhoven: I tried this VIRAL exercise by @gillett_fitness and this one really took bicep training to a whole new level! If your biceps have been lacking then you know you need to try this. This is a very advanced bicep movement and I would not recommend this unless you are very experienced in the gym. Nonetheless it was a challenge to say the least! Try it and let me know whether you gave it a pump 💪🏻 or dump 👎🏻 #biceps #gym #armday #gymtips #bicepworkout
