The best bicep pump workout to blow up your arms

The best bicep pump workout to blow up your arms

Understanding how the biceps function can help you to get a better workout by picking the optimal pump-inducing exercises. For example, movements that have you curl with your arms in front of your body train the biceps at a shorter muscle length and thus create a stronger pump (more on this later).

We’ve already created bicep workouts for mass and building muscle. But sometimes, you just want to get a good pump so that your arms look temporarily bigger and more vascular.

That’s precisely what our bicep pump workout is for.

This routine will certainly build size, but the primary focus is inducing the best bicep pump possible rather than maximizing muscle hypertrophy.

1. EZ spider curl — 3-4 sets of 10-12 reps

Performing the spider EZ bar curl will help you to get pumped biceps because the exercise trains your bis at a short muscle length, which is to say, when your shoulders are in flexion. As mentioned, curling with your arms in front of you like this intensifies the peak contraction and thus produces a skin-splitting pump.

The trick is to keep your elbows and shoulders as still as possible while you curl. You don’t want other muscles to become involved and then fatigue before your biceps; otherwise, your biceps won’t receive proper stimulation. Instead, think about moving the undersides of your forearms toward your biceps while keeping everything else locked in place.

Spider curls are helpful in this regard because you can’t swing the weight up with your legs or back because both of these body parts are braced against the bench.

  1. Load some weights onto either side of an EZ bar or use a preloaded curl bar for more convenience.
  2. Place the bar in front of the backrest-end of the weight bench.
  3. Sit on the bench in a reverse position with your torso pressed against the pad and your feet planted securely on the floor.
  4. Reach forward and grab the bar with a shoulder-width underhand grip.
  5. Curl the bar toward your chest while keeping your elbows and shoulders stationary.
  6. Keep lifting the weight until the undersides of your forearms press right up against your biceps.
  7. Squeeze your biceps at the top of the rep and hold the peak contraction for a moment.
  8. Lower the bar in a controlled manner until your elbows are almost (but not quite) locked out.

2. Cable preacher curl — 3-4 sets of 12-15 reps

Few exercises pump up your biceps as much as the one arm cable preacher curl does. This unilateral isolation exercise blasts your biceps with constant cable tension so that they have to work overtime at every point in the rep. That’s right; unlike with free weight preacher curls, you can’t rest at the bottom of a cable preacher curl because the pulley is always exerting some kind of force on your biceps.

The only downside is that you’ll need to wheel a weight bench over to a low pulley, which might not be feasible in all gyms. The good news, of course, is that you don’t need a preacher station for this exercise. So since weight benches are far more commonplace than preacher benches, there’s a good chance that you’ll be able to perform this bicep pump exercise in your gym.

  1. Wheel an adjustable bench up to a low pulley.
  2. Set the backrest to a 30 or 45-degree angle.
  3. Connect a single handle to the pulley.
  4. Grab the handle with an underhand grip, and then brace your arm against the bench’s pad.
  5. Let your elbow extend so that it’s locked out.
  6. Curl the handle toward your shoulder by flexing your biceps forcefully.
  7. Keep curling until you can’t lift the handle any further (when your forearm pushes right up against your biceps).
  8. Squeeze your biceps and hold the peak contraction for a moment.
  9. Release the handle under control until your elbow is almost fully extended.
  10. Repeat the movement with your other arm.

3. Behind the head cable curl — 3-4 sets of 12-15 reps

Behind the head cable curls will give you the best bicep pump of your life, certainly on paper and probably also in reality.

Here’s what I mean.

Training at shorter muscle lengths produces stronger pumps, whereas training at longer muscle lengths creates deeper stretches. Well, the fully shortened anatomical position for the biceps is when your shoulders are in maximum flexion, which is to say when your arm is behind your head (like in a front double biceps pose).

So, in theory, the behind the back cable curl is the absolute best exercise for pumping up your biceps because you couldn’t train your bis in a more shortened or contracted position even if you wanted to; you’ve reached perfection in the land of bicep pumps.

The only way that other movements could possibly produce a stronger pump is if you’re simply more used to them. In this case, you may have a better mind-muscle connection with your biceps on those familiar exercises rather than on this rarely-performed behind the head curl.

  1. Remove the bar from a lat pulldown station and attach a curl bar in its place. Alternatively, connect a bar to a regular high pulley and kneel on the floor.
  2. Grab the bar with a reverse grip.
  3. Curl the bar behind your head until your forearms press right up against your biceps.
  4. Squeeze your biceps as hard as you can once you’re unable to curl the bar any further.
  5. Hold the peak contraction for a second.
  6. Release the bar in a controlled manner until your elbows are almost at lockout.

4. Cable drag curl — 3-4 sets of 15-20 reps

You’ve probably noticed that there are a lot of cable exercises in this routine. Well, that’s simply because cables produce a more potent muscle pump than free weights due to the fact that they provide constant tension and thus give your biceps no opportunity to rest until the set is over.

So if you want to get the best bicep pump workout possible, then make sure to implement constant tension training on all of your exercises—in other words, don’t lock your elbows out until the set is finished—not just on the cables ones.

Performing drag curls with cables targets the long head of the biceps and intensifies the peak contraction of this already pump-focused exercise.

  1. Connect a straight bar to a low pulley.
  2. Grab the bar with a supinated grip.
  3. Drag the bar straight up your body by contracting your biceps. Avoid shrugging the weight up with your traps.
  4. Keep dragging the bar until the undersides of your forearms make forceful contact with your biceps.
  5. Hold the contraction for a moment and then lower the bar under control until your elbows close in on full extension (avoid locking your elbows out completely).

5. Reverse concentration curls — 3-4 sets of 15-20 reps

Even though this routine is a bicep pump workout, you still need to train your brachioradialis and brachialis muscles if you want to achieve complete arm development.

To do this properly, however, you need to put your big strong biceps at a position of mechanical disadvantage so that they don’t dominate the movement. Curling with a reverse grip is the best way to accomplish this because it puts the brachioradialis and brachialis in powerful force-producing positions.

Moreover, because you’re doing reverse grip concentration curls, you’ll naturally get a more potent pump because bracing your arm against your leg helps you to better isolate the target muscles.

  1. Grab a dumbbell with an overhand grip and then sit on the edge of a weight bench.
  2. Brace the arm that’s holding the weight against the inside of your leg.
  3. Allow your elbow to extend so that the dumbbell is close to the floor.
  4. Curl the dumbbell toward your shoulder until the top of your forearm makes firm contact with your biceps.
  5. Hold the contraction for a moment and then lower the weight under control until your elbow is almost locked out.

How to pump up your biceps

To get the best bicep pump workout possible, there are a few training guidelines that you need to follow. While some coaches will recommend various supplements to help you get a biceps pump, these substances offer, at best, very minor benefits that likely won’t be noticeable.

Your best bet is to focus on optimizing your lifting technique for the pump.

That’s what this section is all about.

Perform high rep curls

To get a good pump, you need to place your biceps under sufficient tension. Since high repetition sets last longer than low rep repetition, performing a high rep biceps workout is one of the best ways to intensify your pump because they generate more time under tension.

Training closer to failure—and thus doing more reps per set—will also intensify your biceps pump by making your muscles contract harder.

However, there’s a sweet spot that you don’t want to overstep.

If you train to grinding failure, where you literally can’t complete another rep, then you’ll have to significantly lighten the weight and/or reduce your reps on your subsequent sets, which isn’t ideal for muscle growth.

Instead, you’re better off leaving 2-3 reps in the tank on each set. This way, you can still get a great pump without sabotaging your strength for the rest of the workout.

Train at short muscle lengths

When you train your biceps in their shortened anatomical position (which is to say when your shoulders are in flexion), the peak contraction feels more intense because your biceps are maximally contracted.

Conversely, when you curl with your arms behind your body, you’re placing a greater stretch on your biceps by training them in their lengthened anatomical position. This training style is great for building muscle (as is the other), but it doesn’t produce the same kind of pump because the muscle simply isn’t as contracted.

So if you want to get pumped biceps while you’re lifting, then make sure to prioritize exercises that have you curl with your arms in front of your body.

Or to say it another way, the more flexed your shoulders are when you curl, the stronger the peak contraction (and thereby the muscle pump). That’s why behind the head cable curls are so effective for pumping up your arms.

Use constant tension training

As a personal trainer, I always advise my clients to use a full range of motion so that they stimulate the broadest possible range of muscle fibers and maximize their bicep hypertrophy.

But sometimes, you just want to get the best biceps pump possible.

And for that, you need to stop your curls just shy of lockout so that the lactic acid doesn’t have a chance to escape from your biceps.

I’m not saying that you should perform half reps, although doing partials at the end of a set can certainly enhance your pump. Rather, you should still get a full contraction, but you don’t need to lower the weight all the way down.

Yes, you’ll probably be stimulating fewer muscle fibers by training with partial reps. But maximizing muscle hypertrophy and maximizing your pump are two different goals (although they’re not 100% mutually exclusive). You could always perform separate workouts within the week to cater to both goals optimally.

You could also do a bicep superset session if you’re short on time and want to get a massive pump.

In conclusion

Now that you know how to pump up your biceps as well as which exercises are best for the job, it’s down to you. Make sure to really focus on your biceps during every rep. This mental cue will improve your mind-muscle connection and thus enhance your ability to contract your biceps and get a better pump.

While you can definitely perform a specific bicep pump workout that’s focused on high reps and constant tension training, you can also get a great pump from regular workouts by improving your mind-muscle connection. Sometimes, when you’re struggling to get a pump, it’s not that you’re training incorrectly; it’s just that you need to focus more intensely on stretching and squeezing your biceps.
