Thanks, but I'm looking for more. Book with a lot of exercises, preferably without a lot of text but with many exercises. The quantity is important here
A good book with lots of exercises is Basics in Rhythm, by Garwood Whaley, Meredith Music Publications.
Could you describe a bit what kind of exercises there are and why you think it's could? I could use improving my sense of rhythm, I can be a bit unsteady at times.
