What to Do When Your Triceps Are Lagging Behind Chest and Shoulders

You're doing everything right. You're consistent with your push days, hitting bench press and overhead press with intensity. Your chest is growing, your shoulders are getting wider, but your arms look the same. This guide breaks down exactly why that happens and the precise plan to fix it.

Key Takeaways

• To fix lagging triceps, train them first in your workout, twice a week, before your compound presses.
• Your triceps are lagging because they are only a secondary mover in big presses; your chest and delts do most of the work.
• Aim for 12-20 total direct sets for triceps per week, with each set taken 1-2 reps from failure.
• You must train all three heads of the tricep (long, lateral, medial) with specific exercises for complete growth.
• Expect your pressing strength to drop by 5-10% for the first 2-3 weeks. This is a necessary trade-off for arm growth.
• Stop adding junk volume at the end of your workout. Prioritized, high-quality sets are the only solution.

Why Your Triceps Are Actually Lagging

The answer to what to do when your triceps are lagging behind chest and shoulders isn't more random pushdowns-it's understanding *why* they're being left behind in the first place. You feel that burn in your triceps after a heavy set of bench presses and assume they're getting enough work. They aren't.

Your body is an efficiency machine. When you perform a heavy compound movement like a bench press or an overhead press, your body will use its strongest muscles to move the weight. For 99% of people, that means the pectorals (chest) and deltoids (shoulders) are the prime movers. Your triceps are just assistants, or secondary movers. They help, but they don't do the majority of the work, especially at the bottom of the lift.

This gets worse with ego lifting. When you load the bar with more weight than you can handle with perfect form, your body compensates even more. Your form breaks down, your shoulders roll forward, and you turn the lift into a chest-dominant grind. Your triceps get even less stimulation, and the gap between your chest and arms grows wider.

Tacking on three sets of cable pushdowns at the end of a grueling 60-minute chest and shoulder workout is useless. At that point, your central nervous system is fatigued, your muscles are depleted of glycogen, and you're just going through the motions. This is junk volume. It adds fatigue without providing the powerful growth stimulus a fresh muscle needs.

Your triceps aren't growing because you've never truly prioritized them. You've treated them like an afterthought, and they've responded accordingly.

The Common "Fixes" That Keep You Stuck

When you search for a solution, you find the same recycled advice that sounds good but doesn't solve the core problem. These common "fixes" are why you're still frustrated.

Myth 1: "Just Do More Close-Grip Bench Press"

The close-grip bench press is a great compound exercise. It does shift more emphasis onto the triceps compared to a standard bench press. But it's not a magic bullet. It's still a heavy compound lift where your chest and shoulders can take over if your triceps are the weak link. Many people also experience wrist or shoulder pain from the awkward positioning.

It's a good tool, but it's not a true isolation movement. You can't use it to specifically target the parts of the tricep that are most underdeveloped. It's a B+ solution when you need an A+ plan.

Myth 2: "Just Add More Sets at the End"

If three sets of pushdowns at the end of your workout aren't working, the answer can't be five or six sets. As we covered, this is junk volume. Your triceps are already pre-fatigued from your presses. You can't generate the force or focus required for a true growth stimulus.

Think of it like this: would you try to set a new deadlift personal record *after* running a 5k? No. You'd do it first, when you're fresh. The same principle applies to bringing up a lagging muscle group. More low-quality work is not the answer.

Myth 3: "You Need a Separate Arm Day"

For professional bodybuilders, a dedicated arm day can make sense. For you, a person with a job and a life, it's probably overkill and inefficient. Hitting a muscle group once every seven days is not the optimal frequency for growth. Most research points to a 2x per week frequency being superior for natural lifters.

A dedicated arm day often leads to excessive volume in one session, causing more muscle damage than your body can recover from, and not enough frequency to keep the muscle protein synthesis signal elevated throughout the week. The solution is smarter programming, not just adding another day to your split.

The 3-Step Plan to Force Tricep Growth

This is the plan that works. It's not complicated, but it requires you to change your habits and let go of your ego for a few weeks. This is a specialization phase designed to shock your triceps into growing.

Step 1: Train Triceps First

This is the most important rule. On your push days (or upper body days), you will perform your tricep isolation exercises *before* your compound presses. Read that again. You are flipping your workout on its head.

By doing this, you attack your triceps when you are 100% fresh. You have maximum energy, focus, and strength. You can use challenging weights with perfect form and achieve a mind-muscle connection that's impossible at the end of a workout.

The trade-off: your bench press and overhead press will feel weaker. Expect your numbers to drop by 5-10% for the first 2-3 weeks. This is non-negotiable. You are pre-exhausting a key muscle used in those lifts. Accept it. This temporary dip in pressing strength is the price you pay for bigger arms.

Step 2: Hit All Three Heads of the Tricep

The tricep isn't one muscle; it's three. To get that full, thick look, you need to train all of them. Most people only do pushdowns, which primarily hit the lateral head.

• The Long Head: This is the biggest part of the tricep, located on the back of your arm. It's what gives your arm thickness from the side. To train it, you must do exercises where your arm is overhead, putting the long head on stretch.
• Best Exercises: Overhead Cable Extensions, Dumbbell Overhead Extensions, Skull Crushers (with an EZ bar to save your elbows).
• The Lateral Head: This is the visible "horseshoe" shape on the side of your arm. It gets hit well with movements where your arms are at your sides.
• Best Exercises: Rope Pushdowns, Straight Bar Pushdowns, Dips.
• The Medial Head: This smaller head sits underneath the other two and is crucial for lockout strength. It's activated in most tricep movements, especially those with a reverse grip.
• Best Exercises: Reverse-Grip Cable Pushdowns, Close-Grip Bench Press.

Your program must include at least one overhead movement and one pushdown-style movement each week.

Step 3: Get the Volume and Intensity Right

Volume drives hypertrophy. For a specialization phase, you need to increase your direct tricep volume significantly. Aim for a total of 12-20 hard sets per week. A "hard set" is a set taken to 1-2 reps shy of absolute failure.

Spread this volume across two workouts per week. Here is a sample 8-week specialization plan:

Push Day 1 (e.g., Monday):

1. Skull Crushers (EZ Bar): 4 sets of 8-12 reps
2. Rope Pushdowns: 3 sets of 10-15 reps
3. Bench Press: 3 sets of 6-8 reps (with the reduced weight)
4. Incline Dumbbell Press: 3 sets of 8-12 reps
5. Lateral Raises: 4 sets of 12-15 reps

Push Day 2 (e.g., Thursday):

1. Overhead Cable Extension (with rope): 4 sets of 10-15 reps
2. Dips (bodyweight or assisted): 3 sets to failure
3. Overhead Press: 3 sets of 6-8 reps (with the reduced weight)
4. Machine Chest Press: 3 sets of 10-15 reps
5. Lateral Raises: 4 sets of 12-15 reps

This structure provides 14 direct sets for the triceps, hitting all three heads, and places them at the beginning of the workout for maximum impact.

What to Expect: A Realistic 8-Week Timeline

Change doesn't happen overnight. Following the 3-step plan requires patience. Here’s what the first two months will look and feel like.

Weeks 1-2: The Ego Check

This is the hardest part mentally. Your triceps will be incredibly sore after the first few workouts. Your bench press and OHP numbers will drop. A weight that used to be a warm-up will feel heavy. Do not give in to the temptation to move triceps back to the end of the workout. Trust the process. Focus on perfect form and feeling the contraction in your triceps during the isolation work.

Weeks 3-4: The Connection Forms

The extreme soreness will subside. You'll start to feel a powerful mind-muscle connection. When you do an overhead extension, you will feel the long head stretching and contracting. Your pressing strength will begin to stabilize and may even start to creep back up to your old numbers. You're building the foundation.

Weeks 5-8: Visible Changes Appear

This is when you'll start to see the payoff. Your arms will look fuller in the mirror. The sleeves of your shirts will feel tighter. Your lockout on presses will feel noticeably stronger and more stable. Friends might start asking if you're doing something different for your arms. By the end of week 8, your triceps will no longer be a lagging body part.

After 8 Weeks: The New Normal

After completing the 8-week specialization phase, you have a choice. You can move your tricep exercises back to after your compound presses, confident that they can now handle the work. Or, if you want to continue prioritizing them, you can keep them at the start of your workout. You are now in control.

Frequently Asked Questions

Should I have a separate arm day?

No, it's not necessary for most people. Hitting your triceps twice a week with focused intensity, as part of your push or upper body days, provides a better stimulus for growth than one high-volume arm day every seven days. This approach is more efficient and better for recovery.

How heavy should I go on tricep exercises?

Focus on the 8-15 rep range with perfect form. The weight should be heavy enough that the last 1-2 reps are a real struggle, but not so heavy that you have to use momentum or body English to move it. The contraction is more important than the number on the dumbbell.

What if I feel elbow pain during skull crushers?

Elbow pain is common with straight bars. Switch to an EZ-curl bar, which allows for a more natural wrist position. You can also use dumbbells with a neutral (palms facing each other) grip. If pain persists, substitute the exercise with overhead cable extensions, which are much easier on the joints.

Will my bench press suffer forever if I train triceps first?

No. It will drop for 2-3 weeks, but as your triceps get significantly stronger, they will no longer be the weak link in the lift. After the 8-week cycle, your bench press will likely be stronger than it was before because you've eliminated a major weakness.

Conclusion

Fixing lagging triceps isn't about finding a secret exercise or a magic supplement. It's about strategic, intelligent programming. By prioritizing them, training them first, hitting all three heads, and applying enough volume, you force them to grow. Stop treating them like an afterthought and start training them with purpose.
