What should I do with my dog *before* we go to a dog training class so that she pays more attention?

We have a 7 month old beagle/coonhound mix and going to beginner classes for training.

The trainer said we should exercise her alot before going to class. We don’t want to tire her out too much…but will try more next week….see if it helps.

Are there any other suggestions besides tire the dog out?

Thanks
