Back in December, we took a look at some of the trends we were confident would take off in 2015. Now that we're almost half way through—yes, really—we want to check in on your resolutions and make sure you're also keeping your clients' routines fresh and effective for the spring and summer seasons. And if you were off to a great start this year, but you have fallen into a fitness rut, don't worry. It happens to everyone. We have just the thing to bring a little excitement back to each workout.
