Use playing cards for a creative, client-driven workout

How does it work?
What you are going to need to do is write down 6-10 exercises that will cover all major muscle groups. After that, you will need to decide on a set range [I typically use 3-5] and a rep range. For convenience sake using cards, I keep the rep range from 5-10 reps.

What you will do is have three different groups of cards that a client can choose from. Each group of cards represents exercises, sets, and reps. The client then chooses one card from each pile. The end result? Any combination of 6-10 exercises, 3-5 sets and 5-10 reps.

Tip: Prior to asking clients to choose one card from each section, I will divide each pile up, ensuring that each pile has the designed number ranges. Also, I remove all picture cards to avoid confusion. This is especially useful when training an older population. 

For example, I used this today with a large group I trained. I had three athletes choose from each pile- today their card numbers were 8, 3 and 10. Therefore, 8 pre-determined exercises were utilized, and the set and rep scheme was 3, 10 respectively.
