How Can I Get Nice Muscle Tone and Look Attractive?

Get yourself a personal trainer and work with him or her. If you can't afford one, join a gym and work with their people. You need to get decent professional advice on diet, aerobic exercise and strength training, but you may also still be growing, given your age. This is why I'm suggesting a pro instead of just some generic online advice.

The best way to gain muscle tone is not protein shakes and exaggerated weight lifting. The best way to gain muscle tone is to combine strength training and cardio! Lifting less weight will actually get you more toned than lifting a lot weight! The lighter the weight is the more toned it will get you (this is a fact). As time goes by you can increase your weight and get bigger and be toned! Cardio is essential for toning. Doing moderate cardio (60 to 70% of your max heart rate) is the best way to burn body fat. Burning body fat will cause your muscles to show more! Good luck and don't give up!
