Spring has officially sprung, at least here in DC, which makes the possibilities for exercise infinitely greater! My advice to you all this week: get outside!!! You don't need to go to the gym to get a good workout in, there are plenty of activities you can do outdoors now that the weather is getting nicer.
Running, for starters, is a pretty obvious way to take advantage of the higher temperatures and get some great cardio. For people who aren't particular fans of running, you can still get your heart rate up outdoors with a brisk walk or bike ride. For strength training, you can do so many of the basics right in your own backyard, i.e. pushups, situps, planks, squats etc. If you want to branch out more, try looking up outdoor fitness classes in your area. Lots of major cities offer all kinds of great classes that you can enjoy in the fresh air instead of a stuffy old gym.
So get out there and move! After all, what could be better than getting fit AND getting tan at the same time?!
