Make your beliefs a part of your workout (whether you do that through prayer, doing a daily devotion, or taking time to center yourself both physically and spiritually).
Surround yourself with common beliefs (that can be as complex as your religion or as simple as wanting to talk positively about others) it makes working out so much more enjoyable.
Know your limits (know how far you can reach down when stretching or that you have to take a quick break from squats) but...
Always push yourself (don't just go through the motions of a workout but really push yourself to make the workout worth it).
Yup, that's what I took away from Zumba yesterday. I'm really looking forward to tomorrow morning (especially since the sun is finally starting to show itself earlier) so I'll let ya'll know how that goes too. Until next time, live long and prosper!
