Biceps BLAST!
1) Barbell Curls for 3 sets
Use a weight at which you'll reach positive failure around 10 reps
(Upon positive failure have your spot give you three forced reps and immediately drop the weight to a weight that allow for 5-6 more reps. Again get three forced reps from your spot. Drop the weight one more time and repeat the same method. Be sure to focus on the negative of each forced rep.)
2) Dumbbell Concentration Curls for 2-3 sets
Use a weight at which you'll reach positive failure around 10 reps at this point
(Upon positive failure give yourself a spot with your off hand for three forced reps and immediately drop the weight to a weight that allow for 5-6 more reps. Again do three forced reps. Drop the weight one more time and repeat the same method. Be sure to focus on the negative of each forced rep.)
OR
Run the Rack twice
(Start with a light weight and work your way up to the weight you'd normally get 10 soild reps at. Do 10 reps on the assent for as long as possible but don't worry when you fall short of that mark. Increase 10 pounds with each new set of dumbbells. Five if your not building to a large set. You certainly won't get ten at the weight you normally would. Once you've gotten to the dumbbells you'd usually get ten reps at Stop the assent. Now that your there work your way back down...)
EXAMPLE: 10 for 10, 20 for 10, 30 for 10, 40 for 10, 50 for 8, 60, for 6, 50 for 6, 40 for 5, 30 for 5, 20 for 5, 10 for 5
That's just an example of what it may look like. Your weights and the reps will vary according to what you can do. That's not my workout but simply an example to see.
MERRY CHRISTMAS!!! To your biceps...
