If the thought of strength training makes you squeamish but you're ready to build some muscle, we have a plan for you. This beginner circuit workout will teach you basic exercises while toning you all over. Grab a set of dumbbells (we recommend 5 to 10 pounds) and get at it. If you don't have weights, you can use soup cans or full water bottles — seriously.
Directions: warm up with light cardio for five minutes (see our suggestions on the next slide), then repeat each three-exercise circuit two to three times, resting for 60 seconds between circuits as needed.
