Upper body strength is harder to achieve than lower body strength because we use our legs more in everyday living. Have patience when trying to increase upper body strength: increase slowly–both resistance and duration. Using weights that are too heavy can cause injury and hinder your training objectives. If you try to take two or three steps forward, you may wind up four steps back.
Good old fashioned push-ups are a great way to obtain upper body strength. Start with just a couple, then as those get easy, add a couple more. Before you know it, you’ll be doing fifty and your upper body will be stronger than it’s been in years!
