Jefferson Curls Form Check

First attempt on these. Recently recovered from a lumbar strain, so hoping to get the okay on form before progressing in weight. Thanks!

Hello Jeffrey, thank you for the video - you're in the right place. One correction only - try not to let your hips shoot backwards at the bottom of the JC, and really focus on rounding your lumbar spine as much as possible. Otherwise it looks pretty darn solid to me so far.
