Increase Strength and Size with 5 Exercises

How to Build Dangerous Biceps

When “functional training” got popular, direct arm training took a hit. Even though your main focus should be on compound lifts and other more functional stuff, there’s no reason to totally eliminate direct arm training.

Aesthetically, the biceps are an important muscle group. Athletically, they play a big role as well. It’s not like elbow flexion is suddenly less important for human health and performance just because arm training is associated with bodybuilding and Arnold Schwarzenegger. That’s absurd.

So, if you need to breathe new life, strength, and size into your biceps, give these five lifts a try.


1. Wall Biceps Curl

The shoulders often get too involved during regular curls, but when your elbows are up against a wall, the biceps have to do all the work. This exercise simply targets the biceps in a more focused way (less “cheating” potential), than regular curls. You also teach yourself to stay in an upright posture.

  • Stand with your back against a wall and a pair of dumbbells in your hands.
  • Curl the dumbbells while your elbows are stabilized against the wall.
  • Some movement is fine, but limit forward elbow movement as much as possible.

2. Seated Hammer Curl

When you curl with your hands in a neutral position (hammer grip), you target the brachialis muscle to a higher degree. This muscle lies deeper below the biceps and is a prime mover of elbow flexion. It actually generates more power than the biceps. If you haven’t been training this muscle directly, you’ll likely give your biceps a nice boost with some hammer time.

  • Start seated on a bench with a pair of dumbbells in your hands.
  • Curl the weight up and lower back with control with a neutral (hammer) grip.
  • Make sure to keep an upright posture during the set.

3. Banded Barbell Curl

Regular barbell curls are great, but adding a band makes it even better. When you curl against a band, the tension obviously increases the higher you go. This means the biceps have to produce more tension to finish the curl. Expect a great pump and more arm gains.

  • Stand upright with a barbell in front of you and place one end of a band beneath your feet and the other end in your hands.
  • After you’ve made sure the band tension is evenly distributed in your hands, bend over and take a firm grip on the barbell before you start the curls.
  • Limit the momentum, especially on the last reps when your biceps start to fatigue.

4. Kettlebell Towel Curl

Build your grip while you build your biceps. Having a strong grip is good for being strong overall, but it’s also related to shoulder health. Grip strength is important for both health and performance.

  • Wrap a towel around the handle of a kettlebell.
  • Take a solid grip on the towel before you stand upright, then curl that kettlebell until your grip or biceps fatigue.

5. Dumbbell Concentration Curl

If you need a true isolation exercise, the concentration curl is the way to go. It literally let’s you concentrate on your biceps. Being a unilateral exercise, it’s also a great option for balancing potential left-to-right imbalances, or for post-injury work on the affected arm.

  • Sit on a bench with a dumbbell in your left hand. Place your elbow or lower part of the upper arm toward your left thigh.
  • From a fully extended elbow position, curl the dumbbell up and lower back with control to start position.

How to Add These To Your Training

1. Do 1-2 exercises after your main upper-body workouts.

Add direct biceps (or general arm training) to your current program. Do one or two arm exercises for 2-4 sets of 8-15 reps after you’ve done your main upper-body strength exercises. I recommend a superset with biceps and triceps.

2. Add a standalone arm-training workout to your current program.

Choose three exercises: one for biceps, one for triceps, and one for shoulders. Do them as a tri-set (basically a superset with three exercises) with 8-15 reps per exercise. Perform 3-4 rounds, either added to a regular workout, or as a standalone mini-workout.
