When selecting exercises to be added to routine, it's annoying to be a multi step process.

Purple (screenshot): currently. For selecting you must first select an item, then a pop up occurs and then you have to select it or view the video.

I suggest that selecting is to be by a tick boxes on the right, which would grey-out the button as currently.

Clicking the exercise thumbnail or the entire exercise button would open info with video. This is useful because when adding exercises to routine you first view it to be sure it's correct and having multiple step process it's annoying.
