How to Do Dips: Bench & Parallel Bar Form Guide

The dip is one of the most underrated upper-body exercises in any training program. Unlike the horizontal pushing pattern of a push-up, a dip is a vertical push — your body is suspended in space and your arms work to lock the elbows out against gravity. This shifts the loading dramatically toward the triceps and the lower fibers of the pectoralis major.

A 2014 EMG study published in the Journal of Strength and Conditioning Research measured muscle activation across several upper-body pressing exercises and found that parallel bar dips activate the triceps brachii at over 87% of maximum voluntary contraction (MVC) — making them one of the most effective bodyweight movements for arm development. By comparison, lying triceps extensions and standard push-ups produced significantly lower triceps activation in the same study.

Muscles Worked

• Primary mover: Triceps brachii (all three heads — long, lateral, and medial — driving elbow extension)
• Heavy assistance: Lower pectoralis major (sternal fibers, especially during the forward-lean variation), anterior deltoid (front of shoulder, controls shoulder flexion at the bottom)
• Stabilizers: Rhomboids and lower trapezius (hold the scapulae down and back), serratus anterior (prevents shoulder shrug), core musculature (keeps the legs from swinging)

Chest vs Triceps — How Torso Angle Shifts Emphasis

Torso Lean	Primary Target	Best For
Vertical (chest up)	Triceps (long head emphasized)	Arm size, lockout strength
15-30° forward lean	Mixed triceps + lower chest	Balanced upper-body development
45°+ forward lean (hips back)	Lower chest (sternal pec)	Lower-chest hypertrophy, fuller pec shape

This single lever — torso lean — is what makes dips so versatile. Bodybuilders who want to fill out the lower chest deliberately lean forward and keep the elbows flared slightly outward. Powerlifters and athletes who want raw lockout strength stay upright and tuck the elbows in tight to the body.

If you are brand new to dips, start with the bench dip and progress to parallel bars as soon as you can. Here is the exact sequence for both variations.

Bench Dip — Step by Step (Beginner)

Step 1 — Setup: Sit on the edge of a sturdy bench or chair. Place your hands next to your hips, fingers wrapping over the edge of the bench, pointing toward your feet. Slide your hips forward off the bench until your weight is supported by your arms.

Step 2 — Foot position: For the easiest version, keep your knees bent at 90 degrees with feet flat on the floor close to the bench. To progress, walk your feet further out so your legs are straighter. The hardest bench dip places the heels on an elevated platform (a second bench or low box) directly across from the support bench.

Step 3 — Descend: Keeping your chest up and your back close to the bench, bend your elbows straight back (not flared outward) and lower your hips toward the floor. Stop when your upper arms are parallel to the floor — going deeper stresses the front of the shoulder capsule.

Step 4 — Press up: Push through your palms and extend your elbows back to the starting position. Do not lock the elbows aggressively at the top; a soft lockout keeps tension on the triceps. Aim for 2 seconds down, 1 second pause at the bottom, 1 second up.

Parallel Bar Dip — Step by Step (Intermediate to Advanced)

Step 1 — Mount the bars: Grip a set of parallel dip bars (shoulder-width or slightly wider). Press up to the top position with arms straight, body suspended between the bars, shoulders packed down and away from your ears.

Step 2 — Set torso angle: For a tricep-focused dip, keep your torso as vertical as possible and bring your feet directly underneath your hips. For a chest-focused dip, lean your torso forward 30-45 degrees and let your feet drift slightly behind you. Decide your angle before you start the rep — switching mid-rep makes the movement sloppy.

Step 3 — Descend with control: Bend your elbows and lower your body. Keep your elbows tracking slightly back (for upright) or slightly out (for forward lean) — never let them flare straight to the sides. Lower until your shoulders are roughly level with your elbows, or stop slightly earlier if you feel pinching in the front of the shoulder. In my experience coaching dozens of trainees, the "parallel arms" cue (upper arm parallel to the floor) is the safest depth target.

Step 4 — Press to lockout: Drive through your palms and squeeze the triceps to extend the elbows. At the top, squeeze your chest if you are doing a chest-focused dip, or hold a slight bend at the top if you are doing the tricep-focused version. Breathe out on the way up.

For step-by-step structured progression markup, this guide follows the standard HowTo pattern — moving from setup through execution with measurable end states (parallel arms, full lockout).

One question I get constantly is "should I do chest dips or tricep dips?" The honest answer is: both, depending on your goal that day. The exercise is identical — the angle of your torso determines which muscle does the most work.

Torso Angle	Elbow Path	Primary Muscle (~%)	Secondary Muscle (~%)
Vertical (0° lean)	Tucked close to ribs	Triceps (~70%)	Anterior delt (~20%)
Slight lean (15°)	Tucked, slight back drift	Triceps (~55%)	Lower chest (~30%)
Moderate lean (30°)	Slight flare allowed	Lower chest (~50%)	Triceps (~35%)
Heavy lean (45°+)	Wider, flared outward	Lower chest (~65%)	Triceps (~25%)

Note: percentages are illustrative based on EMG literature and reflect the general loading pattern, not exact values for every individual.

Programming Both Variations

Within a single weekly training split, you can absolutely use both:

• Push day A (chest focus): Forward-lean parallel bar dips — 3-4 sets of 8-12 reps
• Push day B (arm focus): Upright parallel bar dips — 3-4 sets of 10-15 reps

If you are training each muscle group twice per week, alternating the lean angle gives you targeted stimulus for both muscles without repeating the exact same exercise. This is more efficient than treating "chest dip" and "tricep dip" as two completely separate moves.

For comparison with the horizontal pushing pattern, the standard push-up loads the chest with the body parallel to the floor and emphasizes scapular protraction — a fundamentally different stimulus than the suspended, vertical-push nature of dips.

Dips look simple, but most lifters I have coached make at least one of these five mistakes — and over months these errors compound into elbow tendinitis, anterior shoulder pain, or just stalled progress. Fix them before they cost you.

1. Elbow flare (wings spread): Letting your elbows shoot out 90 degrees to the sides — especially common when fatigued — places massive shear stress on the elbow joint and shoulder capsule. Fix: For tricep-focused dips, tuck the elbows tight to the ribs. For chest-focused dips, allow only a slight outward angle (about 30 degrees from the body). Never go fully horizontal.

2. Shoulder shrug (ears meeting shoulders): When you lose scapular control, your shoulders ride up toward your ears at the bottom of the rep, pinching the rotator cuff against the acromion. Fix: Before every set, actively pull your shoulder blades down and back as if tucking them into your back pockets. Keep that position throughout the rep — if you cannot maintain it, the weight (your bodyweight) is currently too heavy and you need an assisted variation.

3. Partial range of motion (half reps): Stopping with the elbows still well above 90 degrees of flexion shortcuts the triceps and chest stretch — you get a fraction of the benefit. Fix: Lower until your upper arms are parallel to the floor. Use a mirror or film yourself from the side to check depth honestly.

4. Going too deep (shoulders dropping below elbows): The opposite extreme — sinking until your shoulders are well below your elbows — overloads the anterior shoulder capsule. This is the single most common cause of dip-related shoulder pain. Fix: Stop at parallel. If your shoulder feels "pinched" at the bottom, you are going too deep.

5. Swinging and kipping: Using leg momentum to bounce yourself up turns a strength exercise into cardio. Fix: Cross your ankles and squeeze your glutes to lock your body into a rigid lever. The legs should hang dead still throughout the rep. If you cannot do a strict rep, do a slow eccentric (5-second lowering) instead — it builds strength faster than swinging through full reps.
