I'm so grateful that I found this workout. Actually I also found it bc of the story on IG. I've been hoping to tone my arms but don't really enjoy toning them 😅 and I've developed a nasty shoulder issue, after having very good mobility (hypermobile 🙄😭)all my life. During about year the ROM of my shoulder(s) has become smaller and it somehow hurts and feels tense in my upper arm when lifting the arm above the shoulder level. Anyway... Every time I do this amazing exercise I feel a warm tingling in my arms and shoulders. Supposedly it loosens the tension and increses blood circulation 🥳😍👌🏼💯
