A strong and toned upper body is important to improve the quality of your daily living and to improve your appearance, particularly in a wedding gown. Most women are very weak in these muscles because day-to-day activities require little upper body strength. By doing these weight training exercises regularly, you'll notice that you're more able to lift and carry things comfortably and that you'll have healthy looking, toned shoulders, arms, and a toned back to show off in your wedding dress.
