Query: Ouch, that hurts!!

This rubber band definitely has enough resistance, but the black part of the band, the part that's supposed to protect your ankles (if you're using it that way), shifts too much, so you're left with doing leg lifts with just the red part. And that hurts! It kind of pinches and leaves a red mark. If I were to need another rubber band, I would definitely search elsewhere.
