Your chest muscles, or pectoral muscles, can be developed through multiple varieties of resistance exercises. With dumbbells you can build your chest muscles at the gym or at home. A few simple exercises, with the appropriate weight and number of repetitions and sets can lead to larger chest muscles over time. Target your chest two to three times per week to maximize growth potential.
