Gotta be moving the entire time, I thought 30 seconds was hard 🥵 ⠀⠀⠀⠀⠀⠀⠀⠀⠀ It did feel incredibly hard on my elbows so let’s be careful out there people! Recommend only trying this if you can do muscle ups pretty effortlessly, know the technique, and warm up properly 📛 ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀ @adidasterrex | @scarpana | @joerockheads | @verticalartclimbing | @flashedclimbing | @perfect_descent | @CANFund
