Neutral Grip vs Underhand Grip Chin Ups

Why Your Chin-Up Grip Is Limiting Your Gains

When debating neutral grip vs underhand grip chin ups, know this: the underhand grip provides roughly 15% more bicep activation, but the neutral grip is the superior overall back-builder and the safer choice for your shoulders. You're likely stuck wondering which one to use because you've felt it yourself-the underhand grip feels like an arm exercise, while the neutral grip feels more powerful and natural. The truth is, one isn't universally "better," but one is almost certainly better for *you* right now. If your goal is raw bicep size and you have healthy, resilient joints, the underhand grip is a great tool. But for everyone else, especially those looking to build a wider, stronger back or simply get more reps, the neutral grip is your answer. It places the shoulder in a more stable, externally rotated position, reducing the risk of impingement and allowing your lats-the biggest muscles in your back-to do the heavy lifting. Most people who stall on chin-ups do so because their arms give out before their back does. The neutral grip helps fix this imbalance by making it a true back exercise first and an arm exercise second.

The Hidden Mechanics: What's Really Happening to Your Muscles

To understand the difference, you don't need a biology degree. Just hold your arms out. An underhand grip (palms facing you) is called a supinated grip. A neutral grip (palms facing each other) is a semi-supinated grip. This small change in hand position creates a cascade of mechanical shifts up your arm and into your back. With an underhand grip, your biceps are placed in their strongest line of pull. Think of it like doing a standard dumbbell curl. This is why it feels like an arm-dominant movement-it is. You get massive bicep and brachialis activation. The trade-off? This supinated position can put more stress on the wrist, elbow, and shoulder joints, especially under heavy load or high volume. The number one mistake people make is forcing underhand chin-ups when their joints aren't prepared, leading to nagging elbow pain that kills their progress. The neutral grip, however, is the great equalizer. By turning your palms to face each other, you take some of the emphasis off the biceps and shift it directly onto the lats and teres major. It’s a more natural and powerful position for your shoulder to pull from. This allows you to lift more weight or do more reps, which ultimately leads to more back growth. It's not that it doesn't work your arms-it absolutely does-but it allows your massive back muscles to be the primary driver, which is the entire point of a vertical pulling exercise.

The 8-Week Protocol to Double Your Chin-Up Strength

Stop randomly switching between grips. If you want to see a real increase in strength-like going from 3 reps to 6, or 5 to 10-you need a structured plan. This protocol is designed to build a powerful back foundation first, then layer on arm-specific strength. This is for you if you can do at least 1-2 chin-ups but are stalled under 10.

Step 1: Weeks 1-4: The Foundation Phase (Neutral Grip Focus)

Your only goal for the next 30 days is to get brutally strong with the neutral grip. This will build the back strength that is currently holding you back. Forget the underhand grip exists for now.

• Frequency: Perform this workout 2 times per week, with at least 48 hours of rest in between (e.g., Monday and Thursday).
• The Workout: 5 sets of neutral grip chin-ups.
• Reps: On each set, go to technical failure. This means you stop 1 rep *before* your form breaks down. If you can only do 3 perfect reps, your set is 3 reps. Don't cheat.
• Rest: Take a full 2-3 minutes of rest between sets. This is for strength, not cardio. You need your muscles fully recovered to give maximum effort on the next set.
• Progression: Your goal is to add one total rep to your workout each week. If you did 5, 4, 3, 3, 2 reps in week 1 (total 17), you aim for a total of 18+ reps in week 2.

Step 2: Weeks 5-8: The Specialization Phase (Integrating Underhand)

Now that you've built a stronger back, you can introduce the underhand grip as a targeted tool for your biceps without it hijacking the entire movement.

• Frequency: Continue with 2 pulling workouts per week.
• Workout A (Strength Day): Your first workout of the week is your Neutral Grip day. Stick with the 5-set structure from Phase 1. Keep pushing to add reps or, if you can do more than 8 reps per set, add weight using a dip belt (start with 5-10 lbs).
• Workout B (Volume/Hypertrophy Day): Your second workout is your mixed-grip day.
• Exercise 1: Neutral Grip Chin-Ups - 3 sets of max reps.
• Exercise 2: Underhand Grip Chin-Ups - 3 sets of max reps. You will be weaker here, and that's expected. Focus on a full range of motion and feeling the squeeze in your biceps at the top.

Step 3: What If You Can't Do a Single Chin-Up?

If you're starting from zero, your path is different. Your goal is to build the foundational strength to perform that first rep. Do this 2-3 times per week.

• Exercise 1: Eccentric Negatives: Jump up to the top position of a neutral grip chin-up. Hold it for 2 seconds. Then, as slowly as you possibly can, lower yourself down. Aim for a 5-second descent. Do 4 sets of 3-5 reps. Once you can control the descent for 10 seconds, you are ready to attempt a full rep.
• Exercise 2: Inverted Rows: Set a barbell in a squat rack at waist height. Lie underneath it and pull your chest to the bar. This mimics the pulling motion but with less bodyweight. Do 3 sets of 8-12 reps. As you get stronger, lower the bar to increase the difficulty.

Your 60-Day Chin-Up Timeline: What Progress Actually Looks Like

Progress isn't a straight line, and knowing what to expect will keep you from quitting. Following the 8-week protocol, here is a realistic timeline for someone who starts out able to do 3-4 neutral grip chin-ups.

• Week 1-2: You will feel sore, especially in your lats and forearms. The neutral grip will feel more natural by the end of week 2. Your rep count might not jump immediately; your body is adapting. A 1-rep total increase across all sets is a huge win.
• Month 1 (End of Week 4): You should feel a distinct increase in power. Your starting 3-4 reps should now be a solid 5-6 reps on your first set. You've successfully completed the Foundation Phase and built a stronger mind-muscle connection with your back.
• Month 2 (End of Week 8): You're now in the Specialization Phase. Your neutral grip chin-up should be approaching 7-8 reps on the first set. You'll notice that while you can do fewer underhand chin-ups (maybe 4-5 reps), the quality of those reps is much higher because your back is now strong enough to assist properly. You're no longer just using your arms. This is the point where you've broken the plateau. The warning sign to watch for is sharp pain. Muscle burn is good; sharp, localized pain in your elbow, wrist, or shoulder joint is a signal to stop and reassess your form.

Frequently Asked Questions

Grip Width for Neutral and Underhand Grips

For both neutral and underhand grips, a shoulder-width position is optimal. Going too wide with an underhand grip puts extreme stress on the wrists. Going too narrow can limit your range of motion. Place your hands directly in line with your shoulders for the best balance of safety and effectiveness.

Alternating Grips Within a Workout

Yes, but do it with purpose. A great strategy is to start your workout with the grip that aligns with your primary goal for that day. If it's a back-focused day, begin with 3-4 sets of neutral grip chin-ups. Then, finish with 2 sets of underhand chin-ups to target the biceps.

The Role of Overhand (Pronated) Pull-Ups

Overhand pull-ups are a third, distinct variation. They are the most difficult for most people and heavily target the lats and teres major for back width. They are an advanced movement. Master the neutral grip first to build foundational back strength before focusing heavily on wide-grip overhand pull-ups.

Managing Wrist or Elbow Discomfort

If you feel pain (not soreness) with the underhand grip, stop using it for 2-3 weeks. Focus exclusively on the neutral grip, which is much kinder to the joints. Also, incorporate wrist stretches and forearm foam rolling to improve mobility and reduce tension that can lead to elbow pain.
