Tough to answer without more client info. The answers provided already are wonderful but sometimes the clients are depressed and unmotivated, or mentally difficult to instruct.
If that’s the case I’d inject some fun with throwing a balloon in the air and traveling distances (think volleyball serve), outside on different safe surfaces. Ask if they used to play any sports and make up a game around that. Whatever you do, make it fun, interesting, positive and think outside the box! You are the highlight of their day.
