Exercising biceps is simple but you have to have good form to keep from injuring your joints and tendons. The motion is simple bring the weight to your chest back down to rest position. My program is for all ages but focused on 40 and up. Start with about 80% of your max lift to failure then drop 20 lbs and lift to failure and so on try to do at least 3 sets. With biceps there are 3 main exercises which I focus on they are concentration curls, preacher curls and standing curls but I only focus on 2 because other exercises are working the biceps too. Going to failure is more important than reps if you are building strength, reps are more important if building size. To build a peak on your biceps when you return to rest position go slowly down. Like I said there are other exercises that incorporate bicep curls.
