How Deep Should You Go on Dips for Chest

The Only Dip Depth That Matters (And It's Not 'As Low As Possible')

The answer to how deep should you go on dips for chest is simple: lower yourself until your upper arm is parallel to the floor, forming a 90-degree angle at the elbow. Going any deeper puts your shoulder joint at risk for zero extra chest growth. You've probably heard the gym-bro advice to go “ass to grass” on every exercise, and for dips, that translates to dropping until your shoulders are nearly touching your hands. This is not only unnecessary, it's the fastest way to get a shoulder impingement that will sideline your entire upper body routine for months. You're searching for this because you've either felt that dreaded pinch in the front of your shoulder, or you're doing endless reps and only feeling it in your triceps. You're not getting the chest development you want. The truth is, the point of maximum tension on your pectoral muscles occurs in the range just before and at that 90-degree mark. Every inch you go past that point transfers the load from your chest muscles to the delicate ligaments and tendons in your shoulder capsule. It's a classic case of diminishing returns, where the risk skyrockets while the reward flatlines. Forget what you've seen others do. The goal isn't to look extreme; it's to build your chest effectively and sustainably for years to come. That happens at 90 degrees, period.

Why the 90-Degree Rule Is Non-Negotiable for Shoulder Health

Going past a 90-degree elbow bend on dips is one of the most common mistakes in the gym, and it's rooted in a misunderstanding of how your shoulder works. Your shoulder (the glenohumeral joint) is a ball-and-socket joint designed for incredible mobility, but that mobility comes at the cost of stability. When you perform a dip, as you lower your body, your humerus (upper arm bone) moves within the socket. When you stop at 90 degrees, the tension is held by your chest and triceps, and the joint remains in a relatively stable and strong position. The moment you drop deeper, your shoulders roll forward and inward. This is called anterior humeral glide. The “ball” of the joint slides forward in the “socket,” stretching and stressing the anterior capsule and the long head of the biceps tendon. This is the sharp, pinching pain many people feel. You're literally grinding down the structures that hold your shoulder together. The #1 mistake isn't just going too deep; it's letting the shoulders slump forward at the bottom of the rep to get that extra depth. This completely removes tension from the chest and places it squarely on the joint. A perfect dip keeps the chest up and shoulders pulled back and down, even at the bottom. The 90-degree rule isn't about limiting your range of motion; it's about using the *effective* range of motion that builds muscle without wrecking your joints. The strongest powerlifters in the world protect their shoulders with this exact principle. You should too.

The 3-Step Protocol for Perfect Chest Dips

Knowing the rule is one thing; executing it is another. Follow these three steps to build a powerful dip that hammers your chest while keeping your shoulders safe. This isn't about ego-lifting; it's about precision. We're aiming for 3 sets of 8-12 perfect reps. If you can't hit 8 reps with this form, you need to start with an easier progression, which we'll cover.

Step 1: Master the Forward Lean

The biggest difference between a chest dip and a tricep dip is your torso angle. For chest activation, you must lean forward. Aim for a 15 to 30-degree forward lean throughout the entire movement. To achieve this, get on the parallel bars, lock out your arms, and then consciously push your hips back and allow your upper body to tilt forward. Tuck your chin slightly, as if you're looking at a spot on the floor about 3-4 feet in front of you. This angle pre-stretches the pectoral fibers and ensures they do the majority of the work. If you stay perfectly upright, your triceps will take over, no matter how deep you go. This lean is non-negotiable. If you find yourself becoming more upright as you get tired, the set is over. Reset and focus on maintaining the lean on the next set.

Step 2: Control the 3-Second Descent

Most people bomb the negative portion of the dip, dropping into the bottom position. This is where injuries happen and where you lose a massive opportunity for growth. The eccentric (lowering) phase is where you create the most muscle micro-damage, which is a key trigger for hypertrophy. From the top, locked-out position, take 3 full seconds to lower yourself. Count it in your head: “one-one-thousand, two-one-thousand, three-one-thousand.” Stop when your upper arm is parallel to the floor (that 90-degree elbow bend). Your shoulders should be level with or slightly above your elbows. Pause for a split second at this bottom position, feeling the deep stretch in your chest. Then, drive back up explosively. This controlled negative does two things: it forces you to use your muscles instead of momentum, and it builds the stability and control needed to own the movement and protect your joints.

Step 3: The Smart Progression Plan

Not everyone can jump on the bars and perform 10 perfect bodyweight dips. Here’s how you build up, no matter your starting point.

• If You Can't Do 5 Bodyweight Dips: Start with negative-only dips. Use a box or bench to jump to the top, locked-out position. Then, perform the 3-second controlled descent as described above. Do 3 sets of 5-8 negatives. Once you can do this easily, move to band-assisted dips. Loop a heavy resistance band over the bars and place your knees in it. This will give you a boost out of the bottom. Start with a heavy band and work your way to a lighter one.
• If You Can Do 8-15 Bodyweight Dips: You're in the sweet spot for growth. Continue focusing on perfect form, the forward lean, and the 3-second negative. Your goal is to master 3 sets of 12 reps. Once you can hit 12 reps on all three sets, it's time to add weight.
• Adding Weight: Don't jump to a 45-pound plate. Start by holding a 10 or 15-pound dumbbell between your ankles. Once that becomes too easy, invest in a dip belt. Add weight in small 5-10 pound increments. Your goal is to find a weight that challenges you in the 8-12 rep range. Adding weight is the primary driver of progressive overload for this exercise.

What to Expect: Your 60-Day Dip Timeline

Transforming your dip performance and chest development doesn't happen overnight. It requires patience and consistency. Here is a realistic timeline of what you should feel and see if you stick to the protocol.

• Weeks 1-2: The Awkward Phase. Your first few sessions will feel strange. Focusing on the 90-degree stop point and the forward lean will be mentally taxing. Your numbers will likely drop. If you were previously doing 15 sloppy reps, you might only manage 6-8 perfect ones. This is a win. Your stabilizer muscles, especially in your shoulders and core, will be sore. This is your body learning the new, safer movement pattern. Do not get discouraged. Film yourself to check your depth.
• Weeks 3-4: The 'Click'. Around the one-month mark, the movement will start to feel natural. You'll no longer have to think so hard about every component. You'll be able to feel the stretch in your lower chest at the bottom of the rep without any shoulder pinching. Your strength in the correct range of motion will increase, and you should be comfortably hitting 3 sets of 8-10 bodyweight reps or have successfully added a small amount of weight (10-15 lbs).
• Weeks 5-8 (Month 2): Seeing the Change. This is where the visual results begin to show. Your strength will have increased significantly. You might be adding 20-35 pounds on a dip belt for sets of 8-12. When you look in the mirror, you'll notice more fullness and definition in your lower and outer chest. The dip will feel like a power movement, and you'll have the confidence that you're building your physique without silently destroying your shoulders. This is the foundation for long-term progress.

Frequently Asked Questions

The Difference Between Chest Dips and Tricep Dips

The primary difference is torso angle. For chest dips, you lean your torso forward about 15-30 degrees. For tricep dips, you keep your torso as vertical as possible. The forward lean places more emphasis on the pectoral muscles, while the upright posture shifts the load to the triceps.

What to Do If You Feel Shoulder Pain

Stop immediately. Pain, especially a sharp pinch in the front of the shoulder, is a clear signal that something is wrong. The two most common causes are going deeper than 90 degrees or allowing your shoulders to roll forward. Regress to an easier variation like negatives or band-assistance and focus entirely on form.

Using Dip Machines vs. Parallel Bars

Parallel bars are superior because they are a free-moving bodyweight exercise, forcing you to engage numerous stabilizer muscles in your shoulders, chest, and core. A dip machine locks you into a fixed path, which can be less effective and may not fit your body's natural mechanics. However, machines are a good starting point if you lack the strength for even band-assisted dips.

How Often to Train Dips

For most people, training dips one or two times per week is optimal. As a heavy compound movement, it places significant stress on your muscles and central nervous system. You need at least 48-72 hours of recovery between sessions to repair and grow stronger. Never train them on consecutive days.

Alternatives If You Can't Do Dips

If dips cause pain regardless of form, or if you don't have access to the equipment, the best alternatives for targeting the lower chest are decline presses. The decline dumbbell press and decline barbell press mimic the angle and muscle activation pattern of a chest-focused dip.
