How to do cable triceps pushdown(SZ bar)
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The Cable Triceps Pushdown is the ultimate isolation move for the triceps. By using the SZ bar (the one with the zig-zag shape), you can use an angled grip that feels much more natural for your wrists than a flat straight bar.
This exercise is all about 'elbow extension.' When done right, it builds the strength and size of the triceps, which makes up about two-thirds of your upper arm. It’s a safe, effective way to push your arms to the limit without the risk of dropping a weight on your face.
Why Use It
- Directly targets all three heads of the triceps for maximum arm growth.
- The angled grip of the SZ bar reduces strain on the wrists and elbows.
- Constant cable tension keeps the muscle working through the entire rep.
When to Use It
Program this after your heavy pressing movements (like bench press or shoulder press) to finish off your triceps.
Instructions for Proper Form
Setup
- The Pulley: High position with the SZ bar attached.
- The Grip: Hold the angled parts of the bar with an overhand grip.
- The Stance: Stand close to the cable. Feet hip-width apart, slight bend in the knees.
Execution
- The Anchor: Tuck your elbows into your sides and keep them there like they are bolted in place.
- The Push: Use your triceps to push the bar down until your arms are locked out.
- The Squeeze: Flex your triceps hard at the bottom for a split second.
- The Control: Slowly bring the bar back up to chest height. Stop when your elbows are fully bent but before they start to pull away from your ribs.
Pro-Tip: Imagine there is a pin going through your elbows and into your ribs. Your forearms should be the only thing moving.
Common Mistakes
- The 'Chicken Wing': Letting your elbows flare out to the sides. Keep them tucked!
- Using Body Weight: Leaning over the bar and using your chest/shoulders to 'shove' it down. Stay upright.
- Moving the Elbows: Letting your elbows drift forward and back. This brings in the shoulders and takes away from the triceps.
Level-Specific Fixes
- Beginners: Use a lighter weight and focus on the 'lockout' at the bottom.
- Advanced: Try 'constant tension' reps—don't quite lock out at the bottom and don't quite stop at the top.
Mistakes by Level
Beginner
- Moving the upper arms instead of just the forearms.
- Standing too far away from the machine.
Intermediate
- Rounding the shoulders forward.
- Rushing the top half of the rep.
Advanced
- Using momentum to finish the set.
Mechanics
Use these setup and execution anchors to keep the rep organized, repeatable, and easier to progress.

Setup Requirements
- Set the pulley to the highest setting.
- Attach the SZ (angled) bar.
- Stand close to the machine so the cable is vertical.
Form Checklist
- Are your elbows staying still, or are they moving back and forth?
- Are you standing tall instead of leaning your whole body weight onto the bar?
- Is your grip firm but not white-knuckled?
Range of Motion
Start with your hands at chest height (elbows fully bent) and push down until your arms are completely straight.
Breathing Pattern
Exhale as you push down; inhale as you bring the bar back up.
Tempo Guidance
1 second down, a hard squeeze at the bottom, and 2 seconds on the way back up.
Caution Notes
- If your elbows start to flare out to the sides, lighten the weight.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Building arm size and strength.
- Finishing a 'push' or 'arm' workout.
- Beginners learning to isolate the triceps.
Goal Tags
Rep Ranges
- 8-12 reps for muscle size.
- 12-15+ reps for a metabolic pump.
Set Guidance
3-4 sets.
Rest Guidance
60 seconds.
Frequency
2-4 times per week.
Pairings
- Super-set with Bicep Curls for a complete arm pump.
- Pair with Overhead Extensions to hit the triceps from a different angle.
Audience Notes
- A great choice for anyone who finds straight-bar pushdowns painful on the wrists.
Substitution Targets
- Dumbbell Triceps Extension
- Rope Pushdown
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Single Arm Pushdown
Helps you focus on the squeeze without using your body weight.
Best for: Mind-muscle connection.
Progressions
Drop Sets
Perform a set to failure, drop the weight by 20%, and go again.
Best for: Maximum hypertrophy.
FAQ
Common Questions
Should I lean forward?
A very slight forward lean is okay for balance, but don't hunch over the bar. Your triceps should do the work, not your body weight.
