.."side step jacks"
It's like a jumping jack (which I think of as a star jump) but instead you step left or right with your arms up and then down again when you come back to the middle and again the other way backwards and forwards
I can do it slowly but tried to do a beginner's YouTube workout with fairly quick ones and I couldn't bloody do it at all! Arms and legs all over the place and practically fell over
I've always had bad coordination at certain things so it's not new but I feel like nobody else has trouble with this kind of thing! are there any brain exercises I can do?!
