Everyone has one of those days where you simply cannot propel yourself to the gym (or even onto the stability ball in your living room), but your exercise routine doesn't have to compete with your schedule or mood.

"Workouts should reflect our lives, and what we personally need on any given day," says fitness expert Cameron Shayne, creator of the Budokon exercise DVDs, which feature body-sculpting martial arts and soul-soothing yoga. "Our lives dance between two distinct energies -- the Yin and Yang -- and balancing and feeding these two energies is the key to exercise adherence and good health," says Shayne.

Based on Budokon training -- which has worked wonders for celeb clients such as Courteney Cox Arquette, Jennifer Aniston and Amber Valletta -- Shayne offers two distinct styles of workouts that either supercharge your stamina with dynamic martial arts sculpting (Yang), or target your strength and balance with static yoga poses and deep breathing (Yin).
The next time you pack your gym bag or yawn through a long commute, take a few deep breaths and ask yourself the questions below to pinpoint which routines will serve you best. "Pre-workout, do a fast head-to-toe scan to tune into how your body is feeling and your state of mind, and then you'll know which type of general workout your body and soul really needs," says Shayne. Check out his new Flow & Flexibility DVD ($20) to pick between these techniques, or choose from among other common "energy buzz" routines:
