How to Do the Cable Crunch
Beginner core exercise with machine.
The Cable Crunch is a beginner-level core exercise that puts focused tension on the abs, using machine. As an isolation movement it lets you target the abs directly with less full-body fatigue, so it pairs well as an accessory after your main lifts. It slots into most gym setups, and SSS Workout Assistant will program it automatically when it fits your goal and available equipment.

How to perform it
- 1Attach a rope to the high pulley of a cable machine and kneel facing it.
- 2Hold the rope ends beside your head with your hips high and back from the machine.
- 3Curl your torso down, bringing your elbows toward your thighs and rounding your spine.
- 4Keep your hips still so your abs, not your hips, do the work.
- 5Squeeze at the bottom for a second.
- 6Rise slowly back up until you feel a stretch in your abs.
How to program the Cable Crunch
- Use the Cable Crunch later in your workout as an accessory, after your main compound lifts.
- Warm up with one or two lighter sets before your working sets to prime the movement.
- As an isolation move, 3–4 sets of 10–15 reps works well, resting 45–75 seconds. Chase a strong contraction and controlled tempo over heavy weight.
- To progress, add a small amount of load only after you can hit the top of your rep range with clean form.

What to pair it with
For a balanced session, pair the Cable Crunch with a move for the opposing muscles — the Hyperextension (Back Extension) (lower back) or the Superman (lower back). Alternating the two as a superset saves time, because one side rests while the other works.
