It doesn't take pumping iron or fancy weight machines to get your body in shape. An easy alternative to weight training is resistance bands. They're light weight exercise cords that resemble over sized rubber bands with handles on each end that allow you to perform muscle toning exercises. You tie or loop the band around a sturdy object like a doorknob or you simply stand on it, grab the handles and then perform many of the exercises you would do with dumbbells or fitness machines. The bands come in different strengths from 5 lbs. to 15 lbs. They're compact, lightweight and are easy to take with you if you travel. Invest in good quality bands to ensure they don't break or lose resistance over time.
