I noticed that when some people do Jefferson Curls, they tend to lean their hips back, so that they could get their head closer to the knee, and also makes the exercise easier. Someone told me that my hips should lean forward more, so that my weight is on the top portion of my foot. It DOES feel alot tougher that way, so I just want to check if this is correct, since it wasn't mentioned in the Technique videos
