Does the economy have you working extra hours? Two jobs? Has it left you unable to pay for your gym membership? There's no doubt the whole country is struggling right now. But in times of stress, it's as important as ever not to give up on exercise.

Forbes has several great tips for getting the most from your workout. Whether you have to shorten your workout due to lack of time or just can't exercise as many days as you'd like, there are still steps you can take to keep reaching toward your goals.

Interval training, for one, has been determined an excellent fat burner, and you only need to do it for 10 to 20 minutes at a time. Other strategies include shortening rest time between reps, or even replacing rep time with cardio (such as jumping rope). And, of course, if you find yourself sacrificing time with your partner or family for exercise, you could always combine the two with a long bike ride or hike.

These tough financial times may find you tweaking your workout schedule but if you're creative, you can still keep building your fitness every day.
