How to do cable one arm side triceps pushdown
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
By standing sideways to the cable machine, you change the angle of pull, which can help many lifters 'feel' their triceps better than a standard front-facing pushdown. This variation is excellent for isolating the lateral head of the triceps—the part that creates the 'horseshoe' look on the side of the arm.
Because you are using one arm at a time, you can use your free hand to feel the muscle working or provide stability, ensuring that every rep is high-quality and focused.
Why Use It
- Isolates the triceps with a unique angle of resistance.
- Allows for a stronger peak contraction at the bottom of the rep.
- Single-arm focus helps eliminate strength gaps between your left and right sides.
When to Use It
Use this as a secondary triceps movement after a heavy press. It’s a great way to 'polish' the muscle and get a deep burn without needing heavy loads.
Instructions for Proper Form
Setup
- The Pulley: Move the cable to the top of the rack.
- The Stance: Stand sideways to the machine. If you are training your right arm, your left shoulder should be facing the machine.
- The Grip: Grab the handle with an overhand grip. Pin your upper arm against your side.
Execution
- The Push: Drive your hand down toward your hip by straightening your elbow.
- The Squeeze: At the bottom, flex your triceps as hard as possible for one second.
- The Reset: Slowly let the handle come back up until your forearm is just above parallel to the floor.
Pro-Tip: Keep your wrist 'stiff.' If your wrist bends, you lose tension on the triceps and start using your forearm too much.
Common Mistakes
- Elbow Drift: Letting your elbow move forward and back like a pendulum. Keep it pinned!
- The Lean: Leaning your body weight into the handle to move the weight. Stay upright.
- Short-Changing: Not fully locking out the arm at the bottom.
Mistakes by Level
Beginner
- Letting the elbow travel away from the body.
- Using the shoulder to 'shove' the weight down.
Intermediate
- Moving too fast on the way up.
- Not reaching a full lockout.
Advanced
- Losing core tension and allowing the torso to twist.

Setup Requirements
- Set the pulley to the highest position.
- Use a D-handle or a single-rope attachment.
- Stand sideways to the machine.
Form Checklist
- Is your elbow staying still?
- Are you standing tall without leaning over the weight?
- Is your wrist staying straight?
Range of Motion
Start with your elbow bent at roughly 90 degrees and extend until your arm is fully locked out at your side.
Breathing Pattern
Exhale as you push down; inhale as you slowly return to the start.
Tempo Guidance
3-0-1-1: 3 seconds up, 1 second to push down, and a 1-second hard squeeze at the bottom.
Caution Notes
- Avoid letting the weight pull your elbow forward or upward during the reset.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Targeting the lateral head of the triceps.
- Mind-muscle connection for the arms.
- High-volume accessory work.
Goal Tags
Rep Ranges
- 12-15 reps for hypertrophy.
- 15-20 reps for endurance and pump.
Set Guidance
3 sets per arm.
Rest Guidance
45-60 seconds.
Frequency
2-3 times per week.
Pairings
- Pair with a bicep curl for an arm-focused superset.
- Use after a close-grip bench press.
Audience Notes
- Great for lifters who struggle to feel their triceps during standard pushdowns.
Substitution Targets
- Cable One Arm Tricep Pushdown
- Dumbbell Kickback
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Two-Arm Cable Pushdown
More stable and easier to manage heavier loads.
Best for: Building baseline triceps strength.
Progressions
Slow Eccentric Pushdowns
Increases time under tension.
Best for: Breaking through growth plateaus.
FAQ
Common Questions
Why do this instead of a regular pushdown?
The side angle allows for a slightly different line of pull that many find more comfortable for the elbow and better for isolating the outer part of the triceps.
