Setup

How each one starts

Cable Fly — first steps

  1. Set both pulleys to chest height and choose a light to moderate weight.
  2. Hold a handle in each hand and step forward into a staggered stance.

Single Arm Push-Up — first steps

  1. Start in a push-up position with your hands shoulder-width apart and one hand placed slightly wider than the other.
  2. Engage your core and lower your body towards the ground by bending your elbows, keeping your back straight.

Decision

Which should you choose?

The Cable Fly keeps constant tension on the muscle through the whole range of motion. The Single Arm Push-Up needs no equipment and scales 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.

Answers

Common questions

Is the Cable Fly better than the Single Arm Push-Up?

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 Single Arm Push-Up needs no equipment and scales 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 Single Arm Push-Up 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 Single Arm Push-Up work the same muscles?

The primary muscle is the same: the pectorals. Supporting muscles differ slightly — minimal assistance for the Cable Fly versus triceps, shoulders and core for the Single Arm Push-Up.
