Don't rely on just cardio or just weights! If you want to develop good muscle tone, you have to do both resistance and cardio training. Movements that engage multiple muscle groups at once are very effective. The Squat Curl-Press is one great exercise that will tone the legs, shoulders, core and biceps all in one move. I'm also a big fan of body weight exercises such as; pushups, pull ups and dips. Take a look at my Exercise Library for some strength training/toning ideas. For tone without mass; light but challenging weights and higher repetitions are best. If you want to bulk up and tone, use heavier weights and fewer reps. Cardio training is also necessary because it burns calories, sheds excess fat and helps develop muscle. Check out this link for some great cardio moves that will help you tone while you get your heart rate up. Don't forget, eating a healthy diet plays a large role in achieving your fitness goals.
