@tylerpath: The standing barbell bicep curl is surprisingly a demanding exercise to perform without cheating. A very common way people cheat is by leaning back on the concentric. The cue I like to use to avoid this to keep your glutes squeezed and flex your core. A flexed core naturally will prevent you form wanting to hyperextend your back (or at the very least, make you aware of it) #fyp #Fitness #gym #bodybuilding
