where can I find workout programs to change up things for my clients.

Look through fitness magazines and books at your local bookstore/library, check out acefitness.org which has links for the general population to create their own workouts based on body part, time etc – www.acefitness.org/acefit/, YouTube – but use videos from reliable sources and of course Facebook. I “like” Dailyburn and Girls Gone Strong which both post workouts and up-to-date fitness information.
