The pulling and pushing motion of your arms is generated by your biceps and triceps. Along with your shoulders, these 2 muscle groups are constantly being used on a daily basis to lift, push and pull. Our hands and arms are vital in everyday activities, and also help to strengthen other muscle groups. It would be pretty hard to work your back out by doing lat pull-downs with no bicep or tricep muscles. Simple bicep curls and tricep dumbbell extensions are an easy way to start getting these muscles groups into shape.
