- Do not allow your elbows to excessively drift forward as you curl the weight up as this directs the tension off of the biceps and onto the front delts.
- Do not curl the weight so high up that the tension leaves the biceps. Simply curl the weight to the point where you feel a full contraction in your biceps and then stop there and let the weight back down.
- Keep your elbows pinned at your sides throughout the entire movement and do not allow them to flare outward.
- Keep your wrists aligned in a neutral or slightly extended position. If you flex your wrists during the curling movement it directs more stress onto the forearms.
- In order to get a full stretch in the biceps and utilize the largest range of motion possible, flex your triceps at the bottom of each rep.
- A small amount of natural body sway is fine as you curl the weight, but your back should still be kept relatively straight throughout the exercise to prevent lower back stress.
