TETSUCable Fly vs Isometric Wipers
The Cable Fly and the Isometric Wipers both train the pectorals as their primary muscle. The Cable Fly uses a cable while the Isometric Wipers are bodyweight-only. Here is how they compare and when to pick each.
Side-by-side comparison
| Cable Fly | Isometric Wipers | |
|---|---|---|
| Primary muscle | pectorals | pectorals |
| Body part | pectorals | chest |
| Supporting muscles | — | shoulders, triceps and core |
| Equipment | cable | bodyweight |
| Steps in our guide | 6 | 7 |
How each one starts
Cable Fly — first steps
- Set both pulleys to chest height and choose a light to moderate weight.
- Hold a handle in each hand and step forward into a staggered stance.
Isometric Wipers — first steps
- Start by lying flat on your back on a mat or bench.
- Extend your arms straight out to the sides, perpendicular to your body.

Which should you choose?
The Cable Fly keeps constant tension on the muscle through the whole range of motion. The Isometric Wipers need no equipment and scale through leverage, tempo and reps. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the pectorals adapting.

Common questions
Is the Cable Fly better than the Isometric Wipers?
Neither is universally better — both train the pectorals as the primary mover. The Cable Fly keeps constant tension on the muscle through the whole range of motion, while the Isometric Wipers need no equipment and scale through leverage, tempo and reps. Choose based on your equipment and which movement you can progress consistently.
Can I do both the Cable Fly and the Isometric Wipers in the same program?
Yes, but usually not in the same session — they overlap heavily on the pectorals. A common setup is one as your main movement and the other on a second training day, or alternating them block by block.
Do the Cable Fly and the Isometric Wipers work the same muscles?
The primary muscle is the same: the pectorals. Supporting muscles differ slightly — minimal assistance for the Cable Fly versus shoulders, triceps and core for the Isometric Wipers.
