hey guys, new to the forums here. i'm a long time reader and first time poster. i found that the problem i used to have with biceps is that i used to pick up the heaviest weights i could curl and move them like there is no tomorrow. this didn't really get me anywhere. here is my new bicep workout that gives me the greatest pumps ever. i also noticed a difference in my biceps about two weeks after starting this.
-standing wide grip cable curls - start with a very low weight, say 30 pounds do 10 reps and without resting move the pin down to 40, do 10 reps and move the pin down to 50, repeat and keep going. you're going to move the pin down a total of 5 times, so you will be ending on 80. when you get to 80 do the same process in reverse and end on 30. if this is too much weight use a half plate.
-incline alternating dumbell curls - use light weight and perfect form. throwing heavy weights up in the air like a jackass just to show everybody how big your dick is never got anybody anywhere. 24,20,16
-dumbell preacher curls - make sure you fully extend your arm, this may force you to use embarassing amounts of weight. 12, 10, 8
-cable preacher curls - if you have a light preacher bench just carry it over to the crossover machine or what have you and do some close grip cable curls. i use these because they give me constant tension throughout the entire range of the curl. i also hate the curl machine at my gym. but, this is my favorite arm exercise because it gives me a crazy pump at the end of my workout. 12, 10, 8, drop, drop
when you go in to do biceps it's best to leave your ego at the door. good form and moderately high reps are what works best for me. some people may grow more with lower reps and higher weight, you just have to experiment and find out what works best for you. cheat reps have their place also, make sure to use them only when absolutely necessary.
