In terms of how far to actually go back with the handles, just actively open your arms and pull your arms back behind you as far as you comfortably can, that will be your active range. Minimize any momentum and make sure to straighten arms as you fly forward/in. Control every rep and eccentric! - #gymtiktok #GymTok #chestworkout #chestday #chestdayworkout #gymtips | Petermiljak | Facebook
