Robin's demonstrating a push-up to side plank now this can be done with or without hand weights Robin happens to be using five-pound weights for this demonstration what I want you to notice is she's doing her push-up and then as she brings this arm up it is stopping directly above the shoulder she's not letting it fall back behind her at all does it matter the position of the hands it's however you're comfortable and then straight up right above the shoulder and down this is a push-up to side plank
