I saw a youtuber that would "clap out the crunch" gently instead of scrunching. Thought that was interesting.
I've had the same thing said to me about my hair, when it gets long the weight really weighs it down and my hair goes from coils (bra strap length/bit below shoulders) to waves and spirals (currently at just above my butt). Roots are usually not curly at that point without something to help a little like root clips but the ends get very curly. I remember people telling me during grade school years that my hair isn't naturally curly because the roots are flat. That I must be curling it with an iron. Wtf. People just like to gatekeep.
