- Don't allow your elbows to excessively drift forward or backward as you raise and lower the bar. A bit of movement is normal, but your forearms should be doing the majority of the movement.
- You don’t have to keep your elbows completely tucked in throughout the exercise, but don’t allow them to flare out excessively either. Find the position that feels most natural for you.
- As with all tricep extension exercises, focus on control by using a smooth and deliberate rep cadence. You shouldn't be heaving around very heavy weights or using explosive movements as this can easily lead to elbow injury in the long term.
