For some reason my biceps seem rather underdeveloped compared to the rest of my body. They also seem to get fatigued a lot faster during workouts. I usually do 2-3 exercises w/ 3-4 sets, pyramid style. Anyone have suggestions for improving performance for biceps?

What exercises are you doing? Post your bicep workout.

standing barbell curls
12 reps @ 50 lbs
10 reps @ 60 lbs
8 reps @ 65 (begin to fail around 5 reps)
6 reps @ 65 (begin to fail before I hit 4 reps)

standing alternating dumbell curls
12 reps @ 20 lbs for each arm
10 reps @ 25 lbs for each arm (left arm begins to fail at about 5 reps)
8 reps @ 25 lbs for each arm (same deal, arm begins to fail at 5 reps)

After these two exercises, my biceps feel ok but are totally shot when I try to perform another exercise. Today, I switched out the dumbell curls for preacher curls instead and was able to eak out 4 light sets.

I think part of the problem is that my left arm is noticeably weaker than the left. But my biceps seem to be affected more than my other arm muscles. I feel only slightly sore the days following my bicep workouts.

I'm taking in 150+ grams of protein daily along w/ at least 10g of glutamine.

Here are my stats:
29 yrs old
5'10"
174 lbs
14% BF

post your whole routine soe we can see the context of where biceps fit in...

but I suspect you are "trying too hard" to focus on biceps; and you are probably exhuasting them instead of really working them...

just as a note - I didn't give a rats ass about biceps when I started - my focus was core compound lifts for over all mass gain.
With all my heavy back work, I ended up getting huge gains in my biceps without even really trying (I gained 2 inches in 4 months)
so maybe take an other look at your back work...? :confused:

14% BFTry something like this and see how it works for you:

1 x 12 x 30
1 x 10 x 30
1 x 6 x 40
1 x 3 x 50
1 x 1 x 60
3 x 4-6 x 65

Do barbell or dumbbell curls like this, then do hammer curls using same weight if you can (reduce if needed). Let the weight down slowly (3 count), bring it up quickly (1 count). At the top of the rep, hold and give the bicep(s) a good strong squeeze. Focus on perfect form. Keep your torso straight and don't let your back or momentum help you make the lift. Rest 2 mins or so between sets.

After those two exercises do:

3 x 8 x body weight chin-ups.

See how that does for you...

Hope this helps. :flex:

ok - here ya go:
sunday: chest, triceps, shoulders
monday: abs & HIIT cardio
tuesday: legs
wednesday: HIIT cardio
thursday: back & biceps (backs come before biceps)
friday: abs & HIIT cardio
saturday: rest

on back & biceps days, this is what my routine looks like:
Back
4 sets seated upright rows - pyramid style, 12-10-8-6 (or until failure)
4 sets wide grip pull-downs - pryamid style, 12-10-8-6 (or until failure)

I then proceed to my biceps routine posted above. I typically rest 1 minute between sets and 2 minutes between exercises.

I was considering working biceps first to focus my strength on the weaker muscle group, but I've made such great gains on my back, I didnt want to break the routine.

Try something like this and see how it works for you:

1 x 12 x 30
1 x 10 x 30
1 x 6 x 40
1 x 3 x 50

Thanks! I'll definitely give that a try for my next biceps workout.

John's got the right idea, but he forgot to factor in the weight of the bar. The percentages he uses are from the MAX-OT warmup, which is what i use as well. They are:

50% @ 12
50% @ 10
67% @ 6
80% @ 3
90% at 1

followed by your 4-6 rep sets at maximum weight. However, the percentage isn't of the weight ON the bar, but the TOTAL weight. I assume you're using an olympic curl bar, which is 25lbs, bringing your total up to 90 lbs. So here's how you figure out how much added weight you need for the 50% sets.

(90 total max weight x 0.5 percentage) - 25 bar weight = 20 added weight.

Use this formula for all your workouts and warmup sets. Just remember to change the total weight including the bar (25/45lbs depending on bar) and the percentage. Here's what your bicep warmup should look like:

12 @ 20
10 @ 20
6 @ 35
3 @ 45
1 @ 55

No, the weights I suggested were total weight.
